This report presents a review of field trials of WMA technologies conducted in various countries in the world, with the emphasis on performance differences between WMA and conventional HMA and the identification of field performance data that could…
This report describes the planning and conduct of a validation trial of three warm mix asphalt surfacings (chemical additive, polymer additive, foaming) and a hotmix asphalt ‘control’ surfacing at a site in Melbourne, Australia. Issues addressed…
The Austroads asphalt pavement design process set out in Guide to Pavement Technology – Part 2: Pavement Structural Design (Austroads 2008) utilises a mechanistic procedure to predict the allowable traffic repetitions until asphalt fatigue occurs.…
A study of published information regarding the design and development of stone mastic asphalt (SMA) was undertaken. The main focus was upon obtaining information that had resulted in successful SMA mixes. In most instances the design of SMA had used…
This test was conducted to determine the relationship between wheel tracking characteristics found in a laboratory and rutting in real-world scenarios. A road trial was established in Brisbane at the Mount Coot-tha quarry. The site was chosen as it…
This document provides a guide to preparing samples for asphalt mix design to conform to Austroads design processes. It covers splitting of the raw components as well as compacting cylindrical and prismatic samples. The loose asphalt conditioning…
