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…
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…
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.…
This project achieved the objective of consolidating the available research on the impacts of lower speed limits on network operations. It extended this knowledge to bridge an identified knowledge gap regarding urban arterial roads by modelling the…
The objective of this project was to provide advice to jurisdictions on appropriate speed limit setting policy in light of harm minimisation (the Safe System approach). This advice was based on the improved understanding of the relationships between…
