This new National Prequalification System (NPS) documentation is made available to road agencies and industry to enable the new specialist category for precast concrete to be formally introduced into the NPS.

This report details the experimental phase of an Austroads project to review the specifications and use of geopolymer concrete. The findings indicate that acceptable grades of structural geopolymer concrete can be made for field applications.

This report details investigations that were conducted to verify the new Austroads sprayed seal design guidelines.

To verify the appropriateness of the proposed basic voids factor (Vf), and the initial sealing design approach (and also to validate…

This report describes research into development of a laboratory sprayed seal binder cracking test which can be used to measure the relative fatigue cracking resistance of thin binder films which have thicknesses comparable to the thicknesses of the…

Durability assessment is increasingly becoming an integral part of infrastructure design projects in Australia. One of the key drivers for this is the requirement by asset owners for optimum whole of life cost, minimum construction period and…

The near-surface mounted (NSM) FRP technique has received attention worldwide over the externally bonded FRP strengthening technique. Strengthening of a concrete girders using fiber reinforced polymer (FRP) composites to flexural and shear…

The Huntly Section is a new NZ$415M section of the Waikato Expressway running between Hamilton and Auckland. It will connect the recently completed Ngaruawahia and Ohinewai sections on a route that traverses the Taupiri Ranges within a deep cutting…

In recent years the circumferential wrapping with externally-bonded carbon fibre-reinforced polymer (CFRP) composites has proven to be a promising method for strengthening concrete structures. This is particularly valuable when repairing concrete…

Prestressed concrete I girder bridges constructed in the 1960s and 70s have the potential to restrict transport productivity because their AS 5100.7 assessments can be poor despite satisfactory inservice performance. The primary issue is the shear…

A new steel/concrete composite girder was proposed and applied to continuous girder bridges. The area surrounded by the upper and lower flanges and the web are filled with concrete (CFIG: Concrete filled I-section Girder) at the intermediate support.…
