This report investigates the origins of the current Unconfined Compressive Strength (UCS) criteria that differentiates modified granular materials from bound materials. Based on the review, a number of changes to the UCS design criteria are…

To assess permanent deformation of granular materials repeated triaxial tests are currently used. A previous research project highlighted interest in using a wheel-tracking test to obtain a better agreement with field performance.

A new wheel-tracker…

To assess permanent deformation of granular materials, repeated triaxial tests are currently used in Australia. A previous research project highlighted interest in using a wheel-tracking test to obtain a better agreement with field performance. A…

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…

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…

Recognising the importance to pavement designers, asset managers and policy makers of an improved understanding of the relationship between different multiple axle group loads (single, tandem, triaxles, etc.) and road pavement performance, Austroads…

This Pavement Work Tip provides guidelines for the preparation of granular pavements prior to priming or primersealing.

Over the last decade a considerable amount of research effort has been focussed on the development of a repeated load triaxial (RLT) test procedure to assist practitioners in the use of natural and marginal unbound base/subbase materials in road…

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…

Part 4J of the Guide to Pavement Technology provides information and guidance on: the classification and description of source rocks
