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 outlines the direct and indirect benefits of High Productivity Vehicles (HPV) in Australia. Direct benefits examined include safety, productivity, fuel and environmental savings. An attempt has also been made to estimate indirect…

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.

This report reviews the use of auxiliary brakes by drivers of heavy vehicles on long and steep descents. The research was in response to a number of serious incidents involving runaway trucks on long, steep grades and continued noise complaints from…

Passive control railway level crossings within the road network pose a significant safety issue, both for trains and multi-combination vehicles (MCVs) and restricted access vehicles (RAVs0. In order to have provision for the larger MCVs and RAVs,…

Stabilisation may be defined as a process by which the intrinsic properties of a pavement material are altered by the addition of a stabilisation binder to meet performance expectations in its operating, geological and climatic environment. Part 4L…

Road safety in rural and remote areas of Australia and New Zealand continues to be a major area of concern. Analysis of crash data also shows that a substantial proportion of crashes in these areas involve heavy vehicles. On average there have been…

A road trial was established at Gisborne on the Calder Highway. The aim of the trial was to review the performance of sprayed seals constructed from a number of binder types. Class 170 is typically used in Victoria for sprayed seals and a section…
