This report presents the findings of Austroads Project AT1540 Understanding the impact on pavement surfaces from next generation freight vehicles and developing practical network prediction models and responses. The main purpose of the project was…

This report provides a summary of activities completed during 2015–16 for the Austroads long term pavement performance monitoring project.

Austroads has funded the long-term pavement performance study since late 1994. The project monitors the…

This study sought to extend the understanding of pavement works effects (WE) by extending the scope of WE treatments and evaluation measures previously used.

The study was based on data extracted from Austroads long?term pavement performance (LTPP)…

This report details the experimental program, analysis and findings of the assessment of the impacts of axle mass increases on road deterioration for sprayed seal surfaced unbound granular pavements. Load-damage exponents ranged between two and four…

This document describes the results of field trials held in Christchurch, New Zealand in May 2005. The objective of the trials was to gain further understanding of the complex relationship between the various test devices currently utilised to…

Selection of maintenance techniques is always a balance between the administering authority costs and social and environmental costs and outcomes. This project provides practical information and a methodology (including a worked example) for…

A general literature survey and a user survey was conducted to obtain information on existing data aggregation methods and their status in Australia and New Zealand. The responses to the survey indicated that all agencies use or are close to…

An existing model predicted binder life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters, binder durability (resistance to hardening) and seal…

An existing model predicted maximum seal life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters and binder durability (resistance to hardening).…

This report documents research undertaken to develop a methodology for refining existing road deterioration models for Australasian sealed granular pavements. A review of performance data obtained from accelerated load testing of sealed granular…
