Development of the Dynamic Shear Rheometer Consistency 6% Test Method for Polymer Modified Binders
This report describes research work into the development of a new test method utilising the dynamic shear rheometer (DSR) to conduct consistency 6% at 60 
Accelerated Long-term Ageing Methods for Sprayed Sealing Binders: A Field Validation Study
This report presents the results of a field validation study conducted as part of the development of a new long term ageing test for polymer modified binders used in sprayed seals in Australia. Unaged samples of binders were collected during the…
Performance of Asphalt and Spray Grade PMBs in Sprayed Seals
The Australian polymer modified binder (PMB) specification (AGPT/T190) currently requires different binder grades to be used in sprayed sealing and asphalt applications. This study compared the sprayed seal performance of PMBs representing four AGPT/…
Accelerated Evaluation of the Effectiveness of Supplementary Cementitious Materials to Suppress Damaging AAR Expansion in Concrete Structures

This report provides the results of testing of three potentially reactive aggregates by the accelerated mortar bar test (AMBT) and the concrete prism test (CPT).

The tests were conducted using reference mixes, which contained plain Portland cement as…

Realising 100-year Bridge Design Life in an Aggressive Environment: Review of the Literature

This report details a literature review on durability issues that affect the service life of reinforced concrete structures.

The review focused on information from sources within Australia and overseas, including published literature, standards,…

Bridge Design Guidelines for Earthquakes

Despite the fact that the occurrence of large earthquakes in Australia is rare, the consequences can be fatal and costly. The performance of bridges during and after earthquake events is critical in ensuring that road networks remain operational and…

Guidelines for Design, Construction, Monitoring and Rehabilitation of Buried Corrugated Metal Structures

These guidelines provide essential information regarding Buried corrugated metal structures (BCMS) from the design process, installation, in-service monitoring, through to maintenance and repair procedures. BCMS have been used in Australia as an…

Guidelines for Ensuring Specified Quality Performance in Bridge Construction
Road networks represent a significant asset to governments in Australia and New Zealand. In Queensland the state controlled road network consists of some 33 000 km of road which contains around 2850 bridges and many thousands of culverts. The…
Service Life Prediction of Reinforced Concrete Structures
Concrete is the dominant material of construction in the more than 12,000 bridges and major culverts managed by road authorities in Australia and New Zealand. With an ageing asset, concrete durability is becoming an increasingly significant issue…
Monitoring of Steel Corrosion in Concrete
Concrete is the dominant material of construction in the more than 12,000 bridges and major culverts managed by road authorities in Australia and New Zealand. With an ageing asset, concrete durability is becoming an increasingly significant issue…
