Austroads LTPP and LTPPM Study: Summary Report for 2006/07
This report presents the summary of project activities conducted in 2006/07. A number of suitable sealed granular pavement sites were identified across Australia for inclusion in the LTPP study. An improved revised method was used to calibrate HDM-4…
Impact of Rising Watertables and Salinity in Pavement Performance
Austroads sponsored a technical research project Managing the Impacts of Rising Watertables and Salinity on Pavement Performance . The overall desirable deliverables were tools to assist road authorities to identify those sections of road that are…
Review of Surface Texture Measurement Method for Seal Design Input
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…
Review of Foamed Bitumen Sealing in Australia
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…
Bitumen Emulsions
This report reviewed overseas and Australian experience in using bitumen emulsions. Increasing economic and environmental pressures have induced an increase in demand for the use of bitumen emulsions overseas. However, emulsion sprayed seals are…
Seal Distress Mechanisms: An Initial Study into Flushing
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…
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…
The Development and Evaluation of Protocols for the Laboratory Characterisation of Cemented Materials
The study involved a laboratory assessment of two cemented materials to assess their strength, modulus and fatigue properties. The cemented materials consisted of a hornfels crushed rock and a quartzite siltstone bound with general purpose cement at…
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…
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
