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…

Weigh-in-motion Management and Operational Manual

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…

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…

Review of Specifications for the Collection of Digital Road Imaging

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…

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.…

Asphalt and Seal Life Prediction Models based on Bitumen Hardening
This report documents the surface life prediction models that have evolved from the long term sampling of the bitumen in sprayed seals and thin asphalt surfaces. The estimation of surface life is predicated on the basis of the mechanism of bitumen…
Impact of Climate Change on Road Performance: Updating Climate Information for Australia
Climatic conditions play a significant role in the performance of road infrastructure. Models which have been developed to describe road performance can benefit from accurate knowledge of climatic trends. Without access to complete historical data,…
Future Asset Management Issues No. 2: Impacts of Peak Oil with Increases in Bitumen and Fuel Costs on Road Use and Asset Management Funding
This discussion paper examines the consequences of 'peak oil' for road asset management and identified several key issues as the potential subject of future research to assist asset managers in managing the consequences of 'peak oil'. This paper is…
Future Asset management Issues No. 1: Impacts of Greenhouse Gas Emissions on Asset management
This discussion paper is aimed to identify the issues relevant to the future operations of road network asset managers, arising from the consequences of greenhouse gas (GHG) emission reduction in the context of reducing the impact of climate change.…
