Analytical Study of Performance Models for Unbound Granular Pavements

This report presents an analytical and parametric study to assess the relevance of rutting performance models for unbound granular pavements.

The rutting performance relationship used in the Austroads Guide to Pavement Technology Part 2 – Pavement…

Review of Definition of Modified Granular Materials and Bound Materials

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…

Improved Rut Resistance Characterisation of Granular Bases - Manufacture and Commissioning of a Wheel-tracking Device

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…

Development of a Wheel Tracking Test for Rut Resistance Characterisation on Unbound Granular Materials

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…

The Influence of Multiple Axle Loads on the Performance of an Unbound Granular Pavement under Accelerated Loading: Interim Data Report

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…

Guide to Pavement Technology Part 4A: Granular Base and Subbase Materials
This Guide contains advice on the selection, testing and specification of crushed rock and naturally occurring granular materials for use in pavement base and subbase construction.
Guide to Pavement Technology Part 4J: Aggregate and Source Rock
Part 4J of the Guide to Pavement Technology provides information and guidance on: the classification and description of source rocks
Relative Pavement Wear of an Unbound Granular Pavement due to Dual Tyres and Single Tyres
This report presents the results of testing conducted on an unbound granular pavement with a thin bituminous surfacing using a variety of tyre types and half-axle loads applied using the Accelerated Loading Facility. It was found that the reference…
Development of HDM-4 Road Deterioration (RD) Model Calibrations for Sealed Granular and Asphalt Roads

Improved RD models for sealed granular and asphalt pavements are needed. Pavement performance history data from state road authorities and New Zealand (SRAs) were used for calibrating RD models. The calibration and refinement of RD models is…

Optimum Use of Granular Bases: Construction of Test Pavements

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…
