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…

This Pavement Work Tip is a practical guide to sprayed sealing in areas where a pavement may be affected by drought or salt content in its construction.

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…

This report presents an extensive literature review of pavement surface texture measurement methods with a specific interest in how they affect operator safety and delays to traffic. The literature review shows that there are a number of methods in…

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…

In 1993, Austroads performed an extensive trial of foamed bitumen sprayed sealing in Australia, as a part of environmental and energy effective sealing technology development program. The trials were conducted in various states and reported to be…

A review of bleeding or flushed seals was undertaken to determine what physical changes had taken place within the seal that had resulted in the binder lying at or close to the surface. The evaluation process used a visual appraisal and a digital…

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…

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

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…
