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…

This report presents the results of a laboratory study that was conducted as part of the development of a new-long term ageing (durability) test for bituminous binders used in sprayed seals in Australia.

Among the number of test methods reviewed and…

This report documents the research undertaken for Austroads on bicycle lanes at roundabouts. An extensive literature review informed empirical data gathering.The literature review revealed strong evidence that bicycle lanes on the approach and…

This Pavement Work Tip provides a handy summary of the Austroads AP-T235-13 Guide to the Selection and use of Polymer Modified Binders and Multigrade Bitumens.

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 aim of this project is to investigate intersection crashes with a view to determining suitable intersection approach treatments, and opportunities for better managing speeds through intersections, so as to reduce the severity of intersection…

This Pavement Work Tip outlines the influence of temperature and binder viscosity on handling properties of asphalt using different binders.

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 a handy reference to the recommended practice for cutting sprayed sealing binders.
