This report provides a review on surface characteristics in relation to traffic noise and long-life surfacings. For the conventional asphalt surfacings in general road construction practice, the selection of mix type and size would define two most…

The Elastometer is the key testing instrument for PMB specifications in Australia. The Elastometer operating software and data acquisition system were developed in the 1980s, originally to run under DOS and later upgraded to Windows 3.1. This…

The laboratory characterisation of cemented materials for road pavements has recently been completed in Austroads Project TT1359 Cost-Effective Structural Treatments for Rural Highways. This project concluded there is a need for a substantial…

Polymer modified binders (PMBs) can provide improved service performance over normal bitumens in demanding situations. However, a number of field problems have been experienced with PMBs and some of these have been attributed to property changes…

A major study was undertaken to determine relationships between binder rheological properties and the rut resistance of asphalt mixes, as indicated by the laboratory wheel tracking test. Twelve binders, including three bitumens, a Multigrade binder…

This Pavement Work Tip provides practical remedial treatments for restoring texture to flushed or bleeding surfaces.

This Pavement Work Tip provides practical guidelines for the design of primerseals.

Effective performance of bituminous binders in sprayed seals is a vital element in contributing to the overall performance of the sealed road network in Australia. To this end, Austroads has identified the maintenance of a minimum level of technical…

Over the last decade a considerable amount of research effort has been focussed on the development of a repeated load triaxial (RLT) test procedure to assist practitioners in the use of natural and marginal unbound base/subbase materials in road…

The use of warm mix asphalt (WMA) appears to be increasing throughout the developed world in place of conventional hot mix asphalt (HMA). Acceptance depends upon confirmation of the environmental benefits and that on-road performance is at least…
