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 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…
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…
A weigh-in-motion (WIM) workshop held in Hobart in March 2008 identified a knowledge gap in regard to the management and operation of WIM equipment and associated data. Austroads Project AT1482 aims to fill this gap through establishing national…
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…
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…
Digital road images have many applications for the management of road networks. With the rapid advancements in technology and the wide range of applications of digital images currently available, it is useful to create a set of standard…
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…
This report describes the preparation, testing and results from project TT1358: Cost-effective structural treatments for rural highways: Cemented Materials. Ten granular materials, with a variety of different characteristics such as normal to high…
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.…
