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…

Development of Performance-Based Specifications for Unbound Granular Materials: Part A: Issues and Recommendations
The Austroads Member Authorities (AMAs) are developing a Performance Based Specification (PBS) approach to the specification of unbound granular materials in Australia and New Zealand. There has been general agreement to adopt the engineering…
Development of Performance-based Specifications for Unbound Granular Materials Part B: Use of RLT Test to Predict Performance
The Austroads Member Authorities (AMAs) are developing a Performance Based Specification (PBS) approach to the specification of unbound granular materials in Australia and New Zealand. There has been general agreement to adopt the engineering…
Pavement Strength in Network Analysis of Sealed Granular Roads: Basis for Austroads Guidelines
This technical report resulted from a study to develop Austroads guidelines on network level assessment and analysis of data on pavement structural condition. This report outlines the benefits of network level assessment of the structural condition,…
Dust Laying with Bitumen Emulsions
This Pavement Work Tip describes the use of bitumen emulsion for dust laying on unsealed granular pavements to reduce dust nuisance, maintenance costs and loss of pavement material.
