TfNSW QA SPECIFICATION B310

COMPRESSION SEAL EXPANSION JOINTS

1 GENERAL

1.1 SCOPE

This Specification sets out the requirements for the design, supply and installation of preformed

elastomeric compression seals of the open-cell type and the adhesive lubricant used for their insertion

into concrete or steel faced bridge deck joints.

The seal must have multiple webs and accommodate compression by folding inwards at the top.

1.2 STRUCTURE OF THE SPECIFICATION

This Specification includes a series of annexures that detail additional requirements.

1.2.1 Schedule of Identified Records

The records listed in Annexure B310/C are Identified Records for the purposes of Specification

TfNSW Q Annexure Q/E.

1.2.2 Referenced Documents

Unless specified otherwise or is specifically supplied by the Principal, the applicable issue of a

referenced document must be the issue current at the date one week before the closing date for tenders,

or where no issue is current at that date, the most recent issue.

Standards, specifications and test methods are referred to in abbreviated form (e.g. AS 1234). For

convenience, the full titles are given in Annexure B310/M.

1.3 APPROVED BRIDGE COMPONENTS AND SYSTEMS

Unless approved otherwise by the Principal, use only TfNSW approved compression seal expansion

joints. Details of TfNSW approved bridge proprietary products can be found at:

http://www.rms.nsw.gov.au/business-industry/partners-suppliers/documents/tenders-

contracts/listofapprovedbridgecomponentssystems.pdf

1.4 WARRANTY

The supply of each proprietary compression seal expansion joint must be accompanied with a

warranty from the joint supplier in the name of Transport for NSW on the serviceability of the joint for

a minimum period of five years from the date of installation. Any joint that becomes defective within

this period must be rectified by the supplier at no cost to the Principal.

2 MATERIALS

Make the seal from vulcanised compound having polymerized chloroprene as the only base polymer.

The material of the seal, as manufactured, must conform to Table B310.1. Cut or buff all test

specimens from a length of preformed seal.

Table B310.1 - Material Properties

Property Requirement Test Method

Tensile Strength 13.8 MPa minimum AS 1683.11 (Dumb-bell test pieces)

Elongation at Break 250% minimum AS 1683.11 (Dumb-bell test pieces)

Compression Set 40% maximum AS1683.13 (72 hrs at 100°C)

Ageing: AS 1683.26 (Method A for 72 hours

at 100°C)

Change in Tensile Strength –20% to 0 AS 1683.11 (Dumb-bell test pieces)

Change in Elongation at Break –20% to 0 AS 1683.11 (Dumb-bell test pieces)

Change in Hardness IRHD 0 to +10 AS 1683.15.1

Resistance to Ozone No visible cracking AS 1683.24 (Ozone concentration

100 pphm in air, 20% strain,

100 hours at 40°C)

Low Temperature Stiffening

(Change in Hardness)

IRHD 0 to +15 AS 1683.15.1 (After 7 days

at –10°C)

Change in Volume in Oil +70% maximum AS 1683.23 (Using Oil No. 3, after

72 hours at 100°C)

Note: The Principal may waive the requirement for testing as above provided that:

(a) The elastomer for the manufacture of the seal is supplied by a company which has a third party

certified quality management system to AS/NZS ISO 9001 for the manufacture and supply of

elastomer;

(b) Test certificates are supplied to prove that the elastomer meets the properties specified in Table

B310.1 in Type Tests not more than six months old;

(c) Day to day batch quality control on the manufacture of the elastomer is exercised by performing

a test which accurately measures the cure characteristics of the elastomer and highlights

variations resulting from incorrect ingredients or levels thereof; and

(d) The manufacturer establishes control points and limits on batches which have been Type Tested

and uses these control points and limits for subsequent quality control purposes.

Obtain a Certificate of Compliance from a laboratory with appropriate registration from NATA, or

from an organisation mutually recognised by NATA, to verify the conformity of the seal upon

delivery, with the seal identified by a specific batch number. Provide a Certificate of Compliance not

more than one year old with each size of each seal type/configuration delivered. Provide with the

Certificate a statement that the raw material and manufacturing process detailed in the Certificate have

not changed. When the supply of raw material or the manufacturing process changes, a new

Certificate will be required.



Ed 5 / Rev 2 3

3 DESIGN

The design of the joint must conform to Clause 7.3 of AS/NZS ISO 9001, AS 5100.4 and this Clause.

The compression seal selected must accommodate the specified range of movement on the Drawings.

The actual joint gap, as confirmed from site measurements, and the selected size of compression seal

must:

(a) Permit the compression seal to be inserted;

(b) Allow the seal to compress within the seal’s design movement range to the minimum gap width

at ultimate maximum bridge temperature;

(c) Allow the seal to expand within the seal’s design movement range to the maximum gap width at

ultimate minimum bridge temperature after allowing for ultimate remaining concrete shrinkage

and creep effects and live load rotations.

The joint gap must be configured to prevent the compression seal from being pushed down further into

joint gap than the depth specified for the selected size of compression seal.

4 MANUFACTURE

The seal must conform to Table B310.2.

Following manufacture, each seal must be completely uniform and homogeneous throughout. Reject

any seal showing imperfections, surface splits or indentations.

The permissible tolerances for the seal cross-section are:

Tolerance (mm) = 0.05 x dimension

where “dimension” is the relaxed width or overall depth of the seal in millimetres.

The longitudinal profile of the seal must match the bridge cross section, and be obtained either by

removing a portion of the seal to bend it to the required angle or by joining straight lengths using an

adhesive recommended by the seal manufacturer. The seal must not be field spliced except when

permitted specifically by the Principal.

Table B310.2 – Seal Properties


Recovery of compression seal: ASTM D 3542, Clause 8.2

High temperature recovery

after 72 hours at 100°C

80% minimum

Low temperature recovery

after 72 hours at –10 °C

88% minimum

Notes: (a) Two test samples must be tested simultaneously for each recovery test. The recovery value must

be the average result of the pair of samples, provided that the lowest result does not exceed a

tolerance of 0 to –3% of the minimum specified recovery.

(b) If, after a recovery test, any test sample exhibits adhesion between any internal faces, cracking in

any walls or splitting, reject the batch of seal represented by the sample.



4 Ed 5 / Rev 2

5 ADHESIVE LUBRICANT

The adhesive lubricant must provide sufficient lubrication for insertion of the seal into the joint gap at

ambient temperatures. It must be a moisture cured or chemically cured single or multi component

compound compatible with the seal and substrate and not be affected by moisture. It must bond the

seal to the face of the joint gap and seal the joint against infiltration of moisture.

Use only a lubricant that conforms to Table B310.3 and is recommended by the seal manufacturer.

Verify compliance of the lubricant by submission of a test report issued by the manufacturer or, if

required by the Principal, by a NATA accredited test report.

Table B310.3 – Adhesive Lubricant Properties


Solids content 60% minimum ASTM D 4070, Clause 9.1

Viscosity 20,000 to 300,000 cP ASTM D 4070, Clause 9.2

Lubricating life 2 hours minimum ASTM D 4070, Clause 9.3

Sag No sagging ASTM D 4070, Clause 9.4

Peeling strength test:

500 g load

1000 g load

zero

12 mm

ASTM D 4070, Clause 9.5

6 INSTALLATION

Verify that the joint gap and selected size of compression seal conform to Clause 3.

The compression seal must not be inserted into the joint gap until all deck concrete work in adjacent

spans or abutments is complete, except in the case of seals which are pre-compressed between

permanent steel sections with the assembly fixed in position prior to placing the concrete.

Install the seal in accordance with the manufacturer’s instructions.

The sides of the joint gap must be sound, dry and blast cleaned of all grit and loose particles before

installation of the seal unless required otherwise by the Principal.

Insert the seal into the joint gap using the adhesive lubricant and an insertion tool recommended by the

seal manufacturer.
