Asphalt Fatigue Endurance Limit

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.…

Guide to Pavement Technology Part 6: Unsealed Pavements
Part 6 of the Guide to Pavement Technology addresses unsealed pavements including operational demands of unsealed road surfaces, pavement configurations, floodways, cuts, fills and mine haul roads, the identification of suitable pavement materials…
Review of stone mastic asphalt design concepts

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…

Asphalt Properties and Mix Design Procedures Report from the Brisbane City Council Trial

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…

Preparation of Asphalt Samples for Testing

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…

Review of Relationship to Predict Subgrade Modulus from CBR (California Bearing Ratio)

The Austroads Guide to the Structural Design of Road Pavements: Pavement Design (now the Guide to Pavement Technology: Part 2 – Pavement Structural Design) has been used throughout Australia for over 20 years. Progressive development of the Guide is…

Gisborne Sprayed Seal Binder Trial
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…
First National Survey of Australian Bitumens
Little data is available to allow trends in bitumen properties to be determined or to compare the properties of bitumens used in different jurisdictions. Such information will become important as more imported, non-traditional bitumens are used in…
