Standard Kerb Types and Installation Details

Foreword

SHEET 1 of 1


Foreword

The City of Perth has adopted an approach for street enhancement projects to

introduce more resilient granite kerbs to city centre streets; maintaining exposed

aggregate concrete footpaths for the majority of situations; and identifying high

profile locations for granite footpaths. This approach provides for a staged

transition towards full granite footpaths in the future.

The kerb material required for street enhancement projects varies depending on

the level of amenity proposed, as addressed in Book 300 - Standard Footpath

Design and Installation Details. The various levels of amenity call for three types

of kerb material to be used in street enhancement projects and can be found in

the following chapters:

Chapter 410 - Standard Granite Kerbs

Chapter 420 - Standard Precast Concrete Kerbs

Chapter 430 - Standard In-situ Concrete Kerbs

These chapters set out the standard dimensions and installation details for the

different kerb types.

In-situ Concrete Kerbs

General Specification

SHEET 1 of 1

In-situ Concrete Kerbs

1) Use of In-situ Concrete Kerbs

In-situ concrete kerbs is the preferred method of construction for semi-mountable and

mountable kerbs in areas where concrete kerbs are to be used.

Generally, in-situ kerbs have a limited life and are high maintenance. For this reason in-situ

concrete kerbs shall only be used in locations which require barrier and flush kerbs when

there is no possibility of using standard precast kerbs; for reasons such as precast radius

pieces do not fit (and cannot be altered to fit) for on-site requirements.

2) Concrete

All concrete used in the manufacture of in-situ kerbing shall have a minimum compressive

strength of 32MPa at 28 days. It shall have a maximum aggregate size of 14mm.

3) Bedding and Keying In

In-situ concrete kerbs shall be layed directly on to the base course material.

In situations where this cannot be achieved, in-situ concrete kerbs are to be keyed in at

1500mm centres. To key in kerbs, the asphalt surface shall be cut to a depth of 50mm,

prior to laying the kerbs.

4) Tolerances

The kerb shall have no deviation exceeding 5mm, measured from a 3m long straight edge.

5) Shrinkage Joints

Shrinkage joints shall be provided at 1000mm intervals, sawn at right angles to the

longitudinal line of the kerb.

6) Expansion Joints

Expansion joints shall be provided at 2000mm intervals and are to be sawn with a diamond

saw, not less than 12 hours after the kerbing has been initially placed. The width of the

joint shall be 7mm, extending the full section of the kerb except at gully pits and tangent

points, where the expansion joints should be formed to be 13mm wide.

All expansion joints shall be sealed with a strip of 'Sarmprene' foam to a depth of 25mm

and top sealed with 'Butyle' mastic seal. The seal shall finish 3mm below the face and top

of the kerb.

6) Curing

After initial set, Concrete surfaces shall be cured for a minimum period of 7 days with a

sprayed application of CALCURE CR or approved equivalent, applied by the method and

rate specified by the manufacturer. Curing compound is to be applied not less than two

hours after surface finishing of the concrete.

For more information about kerbing design refer to www.mainroads.wa.gov.au
