Aggregate Wetting Experiments and Effects on Recommended Polymer Modified Binder Cutter Levels

The work described in this report determines updated cutter level recommendations for S10E and S20E binders. Studies were also conducted to investigate the relationship between the contact angle of water on films of bitumen and PMB binders, and…

The Effects of Heavy Vehicle Single, Tandem and Triaxle Groupings on Sprayed Seal Wear - Stage 1

The majority of sprayed seal design methods around the world are based on the work of Hanson, published in 1935. However, there are growing weaknesses in current sprayed seal design models. Traffic loads have increased, particularly in both the…

Application of New Technologies to Improve Risk Management (Stage 1): Scoping of Potential Technologies

The purpose of this report is to identify new technologies that are potentially useful for asset managers and develop guidelines for the application of selected new technologies for asset/risk management. This report covers the first stage of the…

Investigation into the Properties of Alternative Surfacing Binders and Bitumen Extending Binders

Bitumen is a major component used in the construction of roads in Australia and New Zealand. As it can only be manufactured from a small number of the crude oils in the world, the future supply and cost of bitumen will be directly linked to the…

Segregation and Degradation in Commercial SBS Binders

This study obtained an indication of the proportion of Australian commercially manufactured polymer modified binders (PMBs) liable to segregate, identifed suitable tests to measure segregation propensity and proposes measures to help prevent or…

Review of AASHTO Pavement Design Guide Performance Relationships

This report is an investigation on the development of the performance relationships used in the 2002 AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG). The primary objective of this investigation was to see if these relationships could be…

Bridge Design Guidelines for Earthquakes

Despite the fact that the occurrence of large earthquakes in Australia is rare, the consequences can be fatal and costly. The performance of bridges during and after earthquake events is critical in ensuring that road networks remain operational and…

The Scoping and Development of Probabilistic Road Deterioration (RD) Models

This report is a scoping document aimed at establishing how road deterioration (RD) models can be developed on a probabilistic basis. Deterministic RD models provide an average estimate to a future condition which is not necessarily likely to be…

Austroads LTPP and LTPPM Study - Summary Report 2010-11

Austroads Project AT1064 Long Term Performance Monitoring to Develop Consistent Performance Models has been running since 1994-95. A review of the analysis of US long term pavement performance (US LTPP) data used to validate the performance…

Development of a Nonlinear Finite Element Pavement Response to Load Model

This report presents, improvements implemented for pavement response to load models performed during the Austroads project Developments of Pavement Design Models. There is a large diversity of local materials and significant demand for using…
