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.…

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 Innovative Binder Delivery Systems (Pilot Study)
This report presented a summary of three pilot studies completed on bitumen emulsions, foam bitumen sprayed sealing and warm mix asphalt.Increasing awareness of environmental issues and energy conservation have led to identifying alternative binder…
Horizontal Stresses: Their Measurement in the Field and Assessment in the Laboratory: Project Summary Report
This summary report describes a measurement technology with the capacity to provide estimates of the vehicle pavement interaction through measurements of the horizontal stresses resulting from vehicle movements. A transducer specifically designed to…
Management of an Asphalt Road Trial
The establishment of an asphalt field trial requires considerable planning and usually involves significant resources. The selection of a trial site can significantly affect the likelihood of a clear outcome. The information provided will assist in…
Technical Basis of the Austroads Design Procedures for Flexible Overlays on Flexible Pavements
This publication describes the development of the flexible overlay design procedures included in the Austroads Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design. The origins of two procedures are detailed: a design chart…
Testing Asphalt in Accordance with the Austroads Mix Design Procedures
This document provides advice for users designing asphalt mixes using the Austroads mix design procedures. The advice given should enable users to produce repeatable and valid results. The tests covered in this document are
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…
