Flexible granular pavements protected by sprayed seal surfacings are the backbone of the Australian and New Zealand road networks. Road agencies in Australia and New Zealand have therefore been focused on producing quality, long-lasting sprayed seal…

This report presents the findings of site inspections and binder ageing performance studies associated with two Austroads sprayed seal trial sites constructed near Coober Pedy, South Australia and Cooma, New South Wales. These trials were…

Austroads Technical Specification ATS 5310 sets out the requirements for the supply, fabrication, handling and placement of steel used for the reinforcement of concrete (&lsquo

Austroads Technical Specification ATS 5420 sets out the requirements for the supply of bolts, nuts, screws, washers, studbolts and threaded rods for steelwork. It also includes requirements for the supply of stainless steel fasteners. This…

This test method sets out the procedure for determining the rubber content of a crumb rubber modified binder using a Soxhlet extraction apparatus. This test method is applicable to crumb rubber modified binders used in constructing and maintaining…

Austroads Technical Specification 5340 sets out the requirements for the patch repair of defective concrete using cementitious materials. The process of restoring existing concrete typically includes: breaking back to sound and dense concrete to…

The New Zealand Transport Agency (Transport Agency) has recently published ‘Protective Coatings for Steel Bridges: A Guide for Bridge and Maintenance Engineers’. This was prepared by the authors to optimise the long-term capital and maintenance…

Australian steel standards have stringent requirements in regard to product conformity. According to Australian structural steel standards, the acceptance of steel is conditional on the evidence of compliance provided in rigorous mill test reports/…

This paper describes the changes made to two of the Australian Standards, AS/NZS 2312:2002 – ‘Guide to the protection of structural steel against atmospheric corrosion by the use of protective coatings’ and AS 2832.1:2004 – ‘Cathodic protection of…

Polymer modified binders (PMBs) are increasingly used in road construction as they provide enhanced performance properties compared with conventional bitumen. Even though PMBs show enhanced service properties, they may show degradation or changes in…
