This report presented a summary of three pilot studies completed on bitumen emulsions, foam bitumen sprayed sealing and warm mix asphalt.Increasing awareness of environmental issues and energy conservation have led to identifying alternative binder…

This summary report describes a measurement technology with the capacity to provide estimates of the vehicle pavement interaction through measurements of the horizontal stresses resulting from vehicle movements. A transducer specifically designed to…

The establishment of an asphalt field trial requires considerable planning and usually involves significant resources. The selection of a trial site can significantly affect the likelihood of a clear outcome. The information provided will assist in…

This publication describes the development of the flexible overlay design procedures included in the Austroads Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design. The origins of two procedures are detailed: a design chart…

This document provides advice for users designing asphalt mixes using the Austroads mix design procedures. The advice given should enable users to produce repeatable and valid results. The tests covered in this document are

Improved RD models for sealed granular and asphalt pavements are needed. Pavement performance history data from state road authorities and New Zealand (SRAs) were used for calibrating RD models. The calibration and refinement of RD models is…

Work associated with the gyratory compaction procedure, which is part of the performance based Austroads asphalt mix design procedure, was reviewed. Studies included determination of the design cycles for different traffic levels, the effect of…

This report compares the deterioration of two pavement groups in the US-LTPP program (GPS1 and GPS2) with that of the Australian LTPP GPS1 and GPS2 pavement groups. For the non-freezing group of the GPS1 pavements, the US sections had similar…
