The work documented in this report demonstrates the use of existing Austroads deterministic road deterioration (RD) models in a probabilistic approach to estimate the possible predictions for the dependent variables of these models. This approach…
This report is the first progress report of a four year project which aims to improve the Austroads procedures for the mix and structural design of foamed bitumen stabilised materials.
The report summarises the test methods drafted to date and…
This report provides a brief state-of-the-art review of current traffic speed deflectometer (TSD) practice based on information gained from attending the deflection at road traffic speed workshop held in the UK in June 2012.
The current state of…
Bitumen, an important component used in road construction in Australia and New Zealand, is manufactured from a finite, non-renewable crude oil resource. A number of commercially available alternative binders and bitumen extended binders have been…
This document provides a guide to the selection of modified binders including multigrade bitumens for different treatments and service conditions, and to assist in the use and interpretation of the Austroads Specification Framework for Polymer…
This report provides a worked example for developing skid resistance investigatory level guidelines.
The worked example is sourced from Main Roads Western Australia (MRWA) and relates to texture measurement as a surrogate for skid resistance. A…
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…
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 details the work undertaken in the first year of the three year Austroads project Improving the Estimation of the Cost of Accelerated Road Wear due to Possible Increases in Axle Mass Limits. In 2011-12 the project identified road sites…
