This report presents the summary of project activities conducted during the 2011/12 season, including a summary of the LTPP/LTPPM pavement condition survey results, a brief summary of the development of probabilistic road deterioration (RD) models…
This report details the data collected during the performance assessment of a typical unbound granular pavement under accelerated loading, using the Accelerated Loading Facility (ALF) with single, tandem and triaxle axle group loads.
As part of the…
This report presents details of a Warm Mix Asphalt (WMA) Evaluation Protocol. The Protocol guides the evaluation of specific WMA technologies and processes such as additives, surfactants and foamed bitumen, and sets out the conduct of appropriate…
This report presents the results of the laboratory testing program conducted in support of the validation trial of warm mix asphalt (WMA) and hotmix asphalt (HMA) conducted in Melbourne, Australia, between 2010 and 2012. Although the intention was…
The 2011 Austroads Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design includes an interim procedure for the thickness design of foamed bitumen stabilised (FBS) pavements. This project aimed to validate the interim…
This report presents the results of a laboratory study to investigate development of a new durability test method that is acceptable for use in Australia. The study aimed to develop a more robust long-term ageing test method and resolve the issues…
Stone mastic asphalt (SMA) is a superior asphalt mix with proven performance. As a consequence of the aggregate skeleton, SMA has an open surface. The experience of some road agency and industry members indicates that the open surface of the SMA…
Stone Mastic Asphalt is coarser in gradation than dense graded asphalt and in emphasising the coarseness of the mix it tends to become difficult to compact in the laboratory. Five compaction methods were investigated to determine how these affected…
