Austroads Review Report: Traffic Noise/Long-life Surfacings

This report provides a review on surface characteristics in relation to traffic noise and long-life surfacings. For the conventional asphalt surfacings in general road construction practice, the selection of mix type and size would define two most…

Austroads LTPP and LTPPM Study - Summary Report 2009-10

Austroads Project AT1064 Long Term Performance Monitoring and Model Development was initiated in 1994/95. The project was reviewed in 2003 and later in 2007 by GP Youdale Consulting Engineers to assess the project’s program and progress and, if…

Elastometer Upgrade and Commissioning

The Elastometer is the key testing instrument for PMB specifications in Australia. The Elastometer operating software and data acquisition system were developed in the 1980s, originally to run under DOS and later upgraded to Windows 3.1. This…

Predicting Structural Deterioration of Pavements at a Network Level: Interim Models

Pavement performance data, in terms of Falling Weight Deflectometer (FWD) deflection, was collected from 71 test sections available from the LTPP/LTPPM sites and used to develop structural deterioration models for flexible asphalt and sealed unbound…

Interim Network Level Functional Road Deterioration Models

This report documents the development of interim network level road deterioration (RD) models for the roughness, rutting and cracking of sealed granular pavements.

These RD models can be used at the network level for the strategic analysis of the…

Towards the Revision of Austroads Procedures for the Design of Pavements Containing Cemented Materials

The laboratory characterisation of cemented materials for road pavements has recently been completed in Austroads Project TT1359 Cost-Effective Structural Treatments for Rural Highways. This project concluded there is a need for a substantial…

A Method to Correlate Weigh-in-Motion and Classification Data

This report looks at low-cost vehicle classifiers to provide some indication of pavement loading or gross vehicle mass (GVM). WIM equipment is relatively expensive to install and calibrate, and may not be easily installed anywhere in a road network.…

Measurement of Changes in PMBs during Transport and Storage: A Pilot Study.

Polymer modified binders (PMBs) can provide improved service performance over normal bitumens in demanding situations. However, a number of field problems have been experienced with PMBs and some of these have been attributed to property changes…

Laboratory Study on Relationships Between Binder Properties and Asphalt Rutting
A major study was undertaken to determine relationships between binder rheological properties and the rut resistance of asphalt mixes, as indicated by the laboratory wheel tracking test. Twelve binders, including three bitumens, a Multigrade binder…
Treatment of Flushed or Bleeding Surfaces
This Pavement Work Tip provides practical remedial treatments for restoring texture to flushed or bleeding surfaces.
