1 GENERAL SPECIFICATION OF WORKS
1.1 GENERAL
1.1.1 This Specification, which is the accompanying document to Council's
Engineering Guide for Development, has been compiled to outline Council's
general procedures and practices in respect of all the associated construction
requirements for drainage, roads, erosion control, and ancillary details within
the City of Blacktown.
1.1.2 Council's basic objective is to preserve, enhance and develop the amenity of
the City with specific reference to safety, convenience and long term cost
effectiveness. This Specification has been prepared to assist the Applicant to
proceed with development by fully informing him of Council's requirements
with respect to the construction of assets which will eventually be vested in,
and maintained by Council, to ensure that such works are constructed to a
high standard.
1.1.3 The Documents referred to in this Specification shall include but not be
limited to Engineering Plans, approved by the Council, Blacktown City
Council's, "Engineering Guide for Development", Australian Standards,
"Australian Rainfall and Runoff, Institution of Engineers, 1998" and the
Statutes, Acts and By-Laws of the Governments of New South Wales and
Australia. All of these documents compliment each other and shall be
referenced in conjunction with this Specification.
1.1.4 In this specification, whenever the term "Engineering Plan" is used, this is
deemed to also be a reference to engineering plans associated with
Construction Certificates issued by Council or Private Accredited Certifiers
under the EP&A Act 1979, and Engineering Approvals issued by Council
under the Roads Act 1993 and Local Government Act 1993.
1.1.5 This Document is the Specification defining Construction Details and the
Obligations of Council and the Applicant.
It provides details relevant to the Development and is binding on all works
carried out. Obligations between Council and the Applicant are inherent and
binding once the Engineering Plans have been approved and issued by
Council.
1.1.6 Council's "Engineering Guide for Development", gives guidance to defining
the Engineering Design details required by Council and which must be
followed by the Applicant or his Representative in order to obtain approval of
Engineering Plans.
BLACKTOWN CITY COUNCIL WORKS SPECIFICATION CIVIL – 2005
ENGSPEC Revision 1 - February 2005 1 - 2
1.1.7 No departure or change will be permitted from approved Engineering Plans
during construction except by written consent from Council, or as may be
approved by Council's Representative in the field.
1.1.8 Variations to this specification may only be authorised by Council employees.
Persons accredited or acting under the Environmental Planning and
Assessment Act as private accredited certifiers are specifically excluded from
altering, adjusting or changing this specification in any way.
1.1.9 The Documents, including any written directions issued by Council to the
Applicant, are binding on the Applicant. Council neither accepts
responsibility nor implies or guarantees any directions given to the Applicant
for any subsequent physical or contractual damages received by the
Applicant.
1.1.10 Where in the Documents reference is made to testing and/or sampling by a
NATA registered laboratory, it shall be understood that the laboratory must
be registered by NATA to undertake the specific tests being referred to.
1.1.11 Non Council Specifications
Where within this specification reference is made to a specification from an external
source such as the RTA and there arises conflict between some part of councils
specification and the external referenced specification then councils specification shall
have priority insofar as the resolution of the point of conflict is concerned.
Where this specification makes reference to an Australian Standard that has been
superseded by a new or updated version, then the new current version shall be deemed to
apply.
1.2 RESPONSIBILITIES OF THE PARTIES
1.2.1 Council's Responsibilities
1.2.1.1 Council Inspections
Council will provide Supervisors to progressively review the work of the Applicant. The
provision of Supervisors in no way limits the Applicant's full responsibility for
completing the works in accordance with sound Engineering Practice and Principles and in
accordance with the intent and purpose of the Documents. Nor does the provision of such
supervisors and the various inspections carried out by them relieve the applicant of any
responsibility to comply with all OH&S responsibilities encumberant upon them by such
works.
BLACKTOWN CITY COUNCIL WORKS SPECIFICATION CIVIL – 2005
ENGSPEC Revision 1 - February 2005 1 - 3
1.2.1.2 Final Approval
Final approval of the works will be issued by Council after inspections and receipt of
relevant documents from the Applicant showing compliance of the Works with the
Documents and once all Bonds, Fees, Contributions and other Monies required by Council
have been paid.
1.2.1.3 Notices to be in Writing
All notices, applications and requests given to the Applicant by Council during the Works
will be given in writing. The Applicant will not be entitled to rely upon any verbal notice,
application or request, notwithstanding any arrangement to the contrary at any time.
1.2.2 Applicant's Responsibilities
1.2.2.1 The Documents
The Works shall be completed in accordance with the intent and purpose of the
Documents. The approved copies of the Documents must be kept on-site at all times and
be available for inspection by Council.
1.2.2.2 Access by Council
The Applicant must allow complete and unhindered access of Council to the site of works
for the purpose of inspecting materials and the Works in Progress.
1.2.2.3 Work by Service Supply Authorities and/or other Contractors
The applicant must permit and maintain trafficable access for Service supply authorities,
their workers and subcontractors at all times. The applicant must not do anything to
hinder such access or to endanger the works being undertaken or the workers undertaking
such works.

received from Council.
BLACKTOWN CITY COUNCIL WORKS SPECIFICATION CIVIL – 2005
ENGSPEC Revision 1 - February 2005 1 - 4
1.2.2.5 Completion of Works
It is the Applicant's responsibility to complete or to cause the completion of the Works in
accordance with the Documents and in a workmanlike manner. Inspection by Council
does not relieve the Applicant of his responsibility to supervise or to arrange the
supervision of the Works. Inspections are for the purpose of enabling Council to satisfy
itself that the Works are being carried out in accordance with the Documents and that the
Works are in a suitable state for Council's acceptance. Consequently, any defects that
develop before the Works are accepted by Council will be required to be made good even
though the defective work may have previously been approved.
1.2.2.6 Cleaning of Gutters and Gully Pits
All gutters and gully pits located within the boundaries of the work shall be cleaned and
kept clean during the period of contract, including the maintenance period, of all silt,
debris, rubbish and surplus aggregate arising out of the execution of the works of the
contract. All requirements of the P&EO Act shall be complied with.
1.2.2.7 Maintenance
All works undertaken within the road reserve shall be fully maintained by the applicant for
the duration of the specified maintenance period.
1.2.3 Private Accredited Certifiers' Responsibilities
Private Accredited Certifiers may issue Construction and Compliance Certificates for
subdivision and development works in accordance with the requirements of the EP&A Act
1979.
Private Accredited Certificates do not have any authority to issue Engineering Approvals
or carry out inspections for works on Public Roads under the Roads Act 1993.
1.3 PRIOR TO COMMENCEMENT
1.3.1 General
1.3.1.1 Council must approve for construction all Documents prepared for the Works.
The Applicant must obtain consents from all relevant Statutory Authorities as
required by Council prior to any works being commenced.

excavation or other work within the footway or carriageway of a public road (road reserve).
Work must not be carried out in a public road unless consent has been granted by the Council (or
other relevant roads authority such as the Roads and Traffic Authority) under the Roads Act 1993.
A person wishing to undertake such work must:
1.15.1 Obtain a Road Opening Permit from the Roads Authority, usually Council,
for routine works such as connection to a kerb and gutter across a nature strip
for a single domestic drainage connection; or
1.15.2 Make special application to Council to obtain stamped approved plans issued
by Council under the Roads Act 1993 for more involved works such as
extension to or creation of new piped street drainage systems, or half width
road construction.
Note 1: Accredited certifiers do not have authority to grant consent under
the Roads Act 1993.
Note 2: Approval for carrying out works in a public road or footway is
granted separately to development consent or a complying
development certificate.
Note 3: The conditions of consent imposed on a DA approval will
generally specify what form of approval is required.

2 TRAFFIC CONTROL FOR WORKS IN PUBLIC ROADS
2.1 DESCRIPTION A "Traffic Control Plan" must be prepared by a suitably qualified RTA accredited work site traffic
designer for all works that are carried out in or adjacent to a public road. This Plan must satisfy
all the requirements of AS 1742.3-2002.
It is the sole responsibility of the Applicant to have in place and maintain traffic facilities, i.e.
barricades, signs, lights, etc, at all times, day and night, seven (7) days a week for the duration of
the works in accordance with the Plan.
These traffic facilities must be installed and maintained by appropriately qualified RTA accredited
work site traffic controllers.
All and any responsibility will rest with the Applicant who shall absolve Council and its
Employees from any suit of law which may result from the failure of the Applicant to comply
with the above requirements.
If it comes to the attention of Council that Traffic Control Devices are insufficient or inoperational
(particularly in an after-hours situation), then Council may arrange to reinstate the Traffic Control
Devices and recoup the costs from the Applicant.
Any changes to the approved Traffic Control Plan must be approved by Council before
implementation.
2.2 ROAD OCCUPANCY LICENCE
The applicant shall ensure that a Traffic Control Plan is submitted to Council for approval at least
10 working days before any works are undertaken on any existing public assets owned,
maintained or controlled by Council. No works shall be commenced until such Traffic Control
Plan has been approved by a Council officer authorised to approve such plans for implementation.
In addition, no work shall commence on any Council assets until such time as the appropriate
occupancy permission has been obtained and the appropriate fees and charges pertinent to such
occupancy paid.

Design" guidelines, or "Managing Urban Stormwater - Soil and Construction - Volume 1" 4th
Edition produced by Landcom (2004).
3.2 GENERAL
Perimeter control measures shall be placed prior to or in conjunction with the first phase of
earthworks. Construction shall be phased if directed by Council so that land disturbance is
confined to areas of workable size. This limits the duration for which disturbed areas are exposed
to erosion. Stabilisation measures shall be applied on the first disturbed section before the next
section is opened up if possible.
Topsoil stockpiles shall be located outside hazard areas such as drainage depressions.
Where site regrading or filling is to be undertaken, surface water shall be directed away from the

Two coat seal
1st application 1 cu.m per 90sq.m. (14mm nominal size)
2nd application 1 cu.m per 120 sq.m. (10mm nominal size)
Council may order variations in the specified rate(s) of application at any stage of the work. In all
cases the following procedure shall be adopted.
Sufficient material shall be at the site to provide the full aggregate cover required for the quantity
of binder to be sprayed at that time. Aggregate at site shall be sufficient to re-run or hand cover
bare or insufficiently covered places left after the first spreading.
The application of aggregate shall commence immediately after the spraying of the binder and
shall be completed within twenty minutes of spraying. Bare or insufficiently covered places shall
be re-run with the mechanical spreader or covered by hand as may be directed. Aggregate in
excess of the rate of application specified or ordered shall be scattered and evenly distributed on
the road.

ENGSPEC Revision 1 - February 2005 9 - 9
In two coat work, before the second course of binder is applied, the first course of aggregate shall
be incorporated thoroughly into the binder by rolling, and if there are any surplus loose particles
on any portions of the sealed area, such portions shall be swept lightly, so as to remove the loose
particles, but not disturb the aggregate bedded in the binder.
This work shall proceed as soon as the first course of aggregate is firmly held by the binder. After
the second application of binder and aggregate, rolling and any necessary drag brooming shall
proceed as specified.
9.15 COMPACTION
After the aggregate has been applied it shall be rolled with an approved pneumatic tyred roller
followed by a steel drum roller.
Rolling of each section of the work shall commence immediately after the application of the
aggregate thereto and shall continue until the aggregate is firmly embedded in the binder. Where
required to ensure an even distribution of aggregate, the surface shall be traversed with a light
drag broom after the initial rolling. If the broom has any tendency to dislodge aggregate particles
bedded in the binder, drag brooming shall be deferred or eliminated and light hand brooming be
substituted. The drag broom shall be in accordance with Section 9.6. Rolling shall be continued
up to a maximum period of 24 hours after the aggregate is applied.
9.16 TRAFFIC
Traffic shall not be permitted to travel on the new work until approved by Council. Traffic shall

mixing plant, capable of uniformly mixing coarse and fine aggregate, filler and binder to
meet the specified requirements at all times.
10.8.2 Temperatures
Thermometer elements of a suitable type, shall be placed in the flow of materials, and
shall be accurate within plus or minus 2%.
Bitumen shall be at a temperature not exceeding 1650C when introduced to the mix.
Aggregates shall be heated to such a temperature that, when filler and binder are added,
the temperature of the mixed asphaltic concrete shall not exceed 1650C.
The mix shall leave the pugmill, drum and/or the hot storage bin(s) at a temperature
between 1400C and 165
0C but in no circumstances shall the temperature of the mix at the
time of laying be less than the minimum value specified in Table 10.1 for the appropriate
road surface temperature and layer thickness.
10.8.3 Mixing Time
Mixing time shall be such that all particles of mineral aggregate are uniformly coated with
binder.
10.8.4 Testing and Acceptance of Mix
Council reserves the right to test the mix at any time to determine its compliance with the
Specification. The Applicant shall be responsible for taking the samples and shall supply
all facilities, equipment and labour for that purpose. The samples shall be taken by the
Applicant's representative at the point of production, along with control samples. The
Council will arrange for the testing of the samples, and the results shall be made available
to the Applicant in due time.
Control testing carried out by a NATA registered laboratory shall be considered as
acceptance testing.
10.9 TRANSPORT
The asphaltic concrete shall be transported by trucks, the bodies of which shall be kept thoroughly
cleaned and coated with a thin film of a suitable release agent to prevent mix sticking to the truck
body.
BLACKTOWN CITY COUNCIL WORKS SPECIFICATION CIVIL – 2005
ENGSPEC Revision 1 - February 2005 10 - 5
During transport the asphaltic concrete shall be covered with a canvas or other suitable cover
which is held down.
Delivery of the mix shall be at a uniform rate within the capacity of the spreading and compacting
equipment. Transport shall be as expeditious as possible to minimise cooling of the asphaltic
concrete.
The mass of all truck-loads of mix shall be measured on a weighbridge certified by the
Department of Consumer Affairs.
10.10 PREPARATION OF PAVEMENT
The pavement shall be dry and free from surface water and shall be thoroughly broomed
immediately prior to commencement. Existing bituminous surfaced pavements shall be groomed
by mechanical means to remove all foreign matter. Any areas significantly affected by oil
contamination shall be cleaned with a suitable cleaning agent.
Under no circumstances shall swept or waste material be placed on the footway or verge at any
time.
Any correction course shall be laid and compacted in accordance with Sections 10.12 and 10.13 to
the general level of the existing surface.
10.11 TACK COAT
The whole of the area to be sheeted shall be lightly and evenly coated with rapid setting bitumen
emulsion (cationic) by mechanical applicator. Unless otherwise approved by Council, such work
shall meet the requirements of current RTA Form 305, "Specification for Supply and Delivery of
Bitumen Emulsion". The application rate of residual bitumen shall be 0.15 to 0.30 litres per
square metre. For bitumen emulsion complying with current RTA Form 305, the application rate
of undiluted bitumen emulsion shall be between 0.25 and 0.50 litres per square metre. If the
bitumen emulsion is diluted, the application rate shall be adjusted to obtain the undiluted rate.
The tack coat shall be allowed to "break" (water separating from the bitumen) and resist picking
up by tyres before the asphaltic concrete is laid. Any over application shall be removed or
dispersed by brushing.
All surfaces to be in contact with AC shall be sprayed with a thin uniform application of tack coat.
Care shall be taken to ensure that the tack coat is not oversprayed, sprayed, or allowed to coat any
other surfaces adjacent to the pavement. Any material so sprayed shall be removed or cleaned to
the satisfaction of Council. The Applicant shall be held responsible for any damage to adjacent
property, vehicles or persons sprayed with tack coating material.

10.12 SPREADING
10.12.1 Paver
Spreading shall be by an approved self propelled paving machine, having an effective
spreading capacity of not less than 50 tonnes of mix per hour and shall be capable of
laying the asphaltic concrete to a true and even finish.
10.12.2 Paving Procedures
Before commencing paving operations the work shall be set out with the order of runs,
position of joints and levels clearly defined.
The paver shall operate at a uniform speed and its output shall match the rate of delivery
of asphaltic concrete such that, as far as practicable, continuous spreading of the mix is
achieved.
Unless otherwise approved by Council, asphaltic concrete shall not be spread by hand
behind the paver. Workmen shall not stand or walk on hot asphaltic concrete except
where necessary for correction of the surface.
Council may approve spreading asphaltic concrete by hand for the correction of minor
irregularities and in areas inaccessible to mechanical pavers. Asphaltic concrete, so
placed, shall be spread so as to produce a smooth even surface with uniform density to the
correct level.
10.12.3 Laying Temperature
The temperature of asphaltic concrete at the time of laying shall be as shown in table 10.1:

BLACKTOWN CITY COUNCIL WORKS SPECIFICATION CIVIL – 2005
ENGSPEC Revision 1 - February 2005 10 - 7
Under no circumstances will AC be allowed to be laid where the pavement temperature is
less than 5ºC or when the surface of the road is wet. Where in the opinion of Council the
spreading and compaction of the mix will be adversely affected by the prevailing weather
conditions, AC will not be permitted to be laid.
Council may reject any part of any truck load which contains lumps of cooled asphaltic
concrete which are liable to affect the quality of the finished surface.
The temperature of the mix shall be measured in the truck just prior to discharging into the
power hopper. A suitable type thermometer readable and accurate to within 20C with a
range from at least 00C to 200
0C shall be used. The temperature shall be measured at a
minimum depth of 200mm and at a location of a minimum of 300mm from the side of the
truck body. An average of at least two readings shall be adopted as a temperature of the
mix.
10.12.4 Layer Thickness and Level
The minimum compacted thickness of the mix shall be 2.5 times the aggregate size and a
maximum of 4 times the aggregate size. The first layer of asphalt (which shall be laid by
the applicant) shall be finished true to line and level and flush with the lip of the gutter on
both sides for the full length of the works.
10.13 JOINTS
Work shall be so arranged that the number of joints, both longitudinal and transverse be kept to a
minimum and the daily laying pattern shall be subject to approval by Council before work
commences.
The density and surface finish at joints shall be similar to those of the remainder of the layer.
10.13.1 Longitudinal Joints
Care shall be taken to provide positive bond between adjoining runs.
Longitudinal joints shall be continuous and parallel. They shall coincide within 150mm
with lines of change of crossfall where such occur. Joints in successive layers shall be
offset by at least 150mm.
Hot joints shall be constructed by leaving an uncompacted strip approximately 150mm
wide along the edge of the first run, and after the adjoining run has been spread, both sides
of the joint shall be rolled simultaneously.
BLACKTOWN CITY COUNCIL WORKS SPECIFICATION CIVIL – 2005
ENGSPEC Revision 1 - February 2005 10 - 8
In the case of cold longitudinal joints, the edge of the first run shall be butted and slightly
elevated while hot using hand lutes. If the edge is left exposed overnight or longer,
Council may direct that the edge be trimmed to a straight vertical face and lightly coated
with tack coat material by brushing. The adjoining run shall be placed against the
prepared edge with an overlap of 25mm to 50mm. The overlap shall be pushed back using
lutes, immediately after placing, to form a slight ridge along the joint which the roller shall
compress adjacent to the edge of the previously placed run. Any excess, overlapping or
segregated material shall be discarded.
The compaction of the mix at a longitudinal joint shall be carried out immediately behind
the paver using either a static steel wheeled roller or a vibratory steel wheeled roller
operated in a static mode.
When thin layers are to be compacted, Council may allow the use of a vibratory steel
wheeled roller operated in the vibratory mode. In this instance, the first forward and
reverse pass shall be made with the roller travelling on the hot lane and with a 150mm
overlap on the cold lane.
Rolling shall continue until the joint is smooth and dense.
10.13.2 Transverse Joints
When the end of the spread material has cooled due to disruption of the work, or when
resuming work on the next day, a transverse joint shall be formed.
Transverse joints shall be at right angles to the direction of paving. They shall be
staggered by at least one metre between successive layers and between adjacent runs.
Runs shall be ended either against a timber bulkhead to ensure a straight vertical, well
compacted edge or by feathering out and compacting. In the latter case, the feathered
material shall be cut back to a line where the full thickness exists. The surface shape of
the end of the run shall be checked by a straight edge to locate the line of cut.
The end of the previous run shall be lightly tack coated before the paving of the next run
proceeds.
The joint shall be rolled with a steel roller transversely for several passes, with the roller
projecting about 150mm further onto the fresh mix in each pass. If a vibratory roller is
used, it shall be operated in the static mode.
Boards shall be used for off pavement movement of the roller to prevent rounding the
edge of the mat. The joint shall then be rolled longitudinally.
When the asphaltic concrete layer is required to join and match the level of an existing
pavement surface, sufficient of the existing material shall be removed to achieve the
minimum specified layer thickness.

when the roller is coming to a halt or changing direction.
10.14.1.3 Pneumatic rollers shall have a mass of ten (10) tonnes to twenty (20) tonnes
ballasted and tyre inflation pressures variable up to 700kPa. Numbers of
wheels may vary from seven to eleven. The tyres shall have wide, flat smooth
rolling surfaces.
For compaction in confined areas or patching works a small vibrating roller,
or hand operated vibrating compactor acceptable to Council, shall be used.
10.14.2 Compaction Procedures
Rollers shall travel at a uniform speed not exceeding 5km/h for steel rollers and 10km/h
for vibratory steel and pneumatic tyred rollers. They shall not remain stationary on
recently compacted mix.
Lateral changes in the direction of rolling shall be made on previously compacted mix.
Vibrating rollers shall not be stopped or reversed while in the vibrating mode.
Vibratory steel rollers shall not be permitted to travel when operating in the vibratory
mode on cement concrete or previously compacted asphaltic concrete.
Compaction shall be considered in three stages, initial, secondary and final rolling:
10.14.2.1 Initial rolling
Initial rolling shall be carried out using steel rollers. Vibratory steel rollers may be used,
but they shall be operated in the static mode for the initial passes. On deep lift asphaltic
concrete, pneumatic tyred rollers may be used. When compacting thin layers, Council
may permit vibratory steel rollers to be operated initially in the vibratory mode.
BLACKTOWN CITY COUNCIL WORKS SPECIFICATION CIVIL – 2005
ENGSPEC Revision 1 - February 2005 10 - 10
Initial rolling shall commence as soon as possible after laying has commenced. Rollers
shall be operated as close as possible to the paver, with their driving wheels closest to the
paver.
The transverse and longitudinal joints and edges shall be compacted first as specified in
Section 10.13. Rolling shall then proceed longitudinally with the roller moving parallel to
the run and reversing along the same track.
The roller shall gradually progress from the lower to the higher edge of the new mat. Each
tract shall overlap the preceding one by about 150mm and shall terminate beyond the end
of the preceding track by at least one metre.
Initial rolling shall be completed before the mix temperature falls below 1050C.
10.14.2.2 Secondary Rolling
Secondary rolling shall immediately follow initial rolling. Either vibratory steel rollers,
static steel rollers or pneumatic tyred rollers shall be used. The tyre pressures of
pneumatic tyred rollers shall be between 500kPa and 600kPa. Rolling shall commence at
the longitudinal joint side of the run, with the roller reversing along the same track on
each pass and shifting across the run in full roller widths to the opposite side.
Secondary rolling shall be completed before the mix temperature falls below 800C.
10.14.2.3 Final Rolling
Final rolling shall be carried out by a pneumatic tyred roller with tyre pressures between
600kPa and 700kPa to eliminate all roller marks and to produce a uniform finish. If any
tyre marks exist after final rolling, Council may direct that they be removed with a steel
roller operated in a static mode.
If secondary rolling has been carried out with a pneumatic tyred roller, a steel roller may
be used for final rolling.
Final rolling shall be completed before the mix temperature falls below 600C.
10.14.2.4 Compaction Requirement
The minimum Characteristic Value of Relative Compaction of a sample core when tested
in accordance with the RTA Form 612 shall be 95% for a layer of thickness less than
50mm or 96% for a layer of thickness of 50mm or greater.
Mix with an actual Characteristic Value of Relative Compaction of less than 90% shall be
removed from the site. (RTA Form 612, Table 11 refers).

ENGSPEC Revision 1 - February 2005 11 - 3
11.7 PLACEMENT OF PAVING UNITS IN ROADS AND FOOTWAYS
11.7.1 Placement of Paving Units in Roads
Paving units shall be placed on the screeded sand bed in the predetermined laying pattern,
care being taken to maintain the specified pattern throughout the job. Paving units shall be
placed to achieve nominal 2 to 4mm (max) wide gaps between adjacent units to correctly
align all joints.
The initial row shall abut an edge restraint and shall be laid at the required angle to
achieve the visual orientation of paving units in the completed pavement. (See standard
drawings A(BS)112M).
In each row all full units shall be laid first. Closure units shall be cut and fitted
subsequently. Units shall be cut by power sawing.
To infill spaces between 25 and 50mm wide a concrete having a 1:2:4
(cement:sand:coarse aggregate) mix and having a colour similar to the paving units may
be used. The nominal aggregate size should not exceed one third the smallest dimension
of the infill space. For smaller spaces dry packed mortar may be used.
Except where it is necessary to correct any minor variations occurring in the laying bond
the paving units shall not be hammered into position. Where adjustment of position is
necessary care shall be taken to avoid premature compaction of the sand bedding.
Any foot or barrow traffic shall use boards overlaying paving to prevent disturbance of
units prior to mechanical compaction. No other construction traffic shall be allowed on
the pavement during the construction process.
Paving units shall be laid in a herringbone pattern unless otherwise specified or directed
and to design levels and grades.
As soon as practical after compaction, and prior to the termination of the work on that day
and prior to the acceptance of construction traffic, sand for joint filling shall be spread
over the pavement. The sand shall pass a 1.18mm sieve and have some 10% of silty
material but be free of all soluble salts or contaminants likely to cause efflorescence or
staining.
The filling sand shall be broomed to fill the joints. At least one pass of the plate vibrator
is required to achieve compaction of joint filling sand.
BLACKTOWN CITY COUNCIL WORKS SPECIFICATION CIVIL – 2005
ENGSPEC Revision 1 - February 2005 11 - 4
As soon as possible after the filling of joints, construction traffic shall be encouraged to
use the pavement to assist in the development of 'lock up'. Such traffic shall traverse the
greatest possible area of the pavement.
Council may direct that, where a pavement is not to be subject to traffic loads for some
time after completion, the Applicant maintain a sand surcharge over the pavement to
inhibit moisture ingress.
Excess surface sand shall be removed by brooming at the end of the Defects and Liability
Period unless otherwise directed by Council.
11.7.2 Placement of Paving Units in Residential Crossing
Paving units shall be placed in accordance with Council’s “Residential Vehicle Crossings”
Specification or as otherwise directed by Council’s Engineer.
11.7.3 Damaged Units
Any units which are structurally damaged during compaction or which are otherwise
damaged on the wearing surface or edges shall be removed and replaced with undamaged
units.
11.7.4 Laying of Paving Units in Footways
The subgrade where paving unit shall be laid shall be prepared to grades and cross-fall
indicated on the documents.
A layer of 75mm thick concrete of a strength of 20 MPa shall be placed upon this prepared
subgrade.
A layer of fine, non-adhesive sand, 25 - 50mm thick when screeded, shall be placed on the
concrete base, screeded and trimmed to level and grade.
Pavers shall then be laid in herringbone pattern, in accordance with Section 11.7.1 in this
Specification.
Damaged units shall be taken up and replaced with new units.
11.7.5 Maintenance
All pavements shall be maintained by the Applicant during the Maintenance Period.
