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…

These guidelines are designed to support nationally consistent implementation of the national model legislative provisions of the Road Transport Reform (Compliance and Enforcement) Bill approved by Australian Transport Ministers in November 2003.…

The purpose of this document is to provide administrative guidelines that are consistent with the national model Road Transport Reform (Compliance and Enforcement) Bill (the

This project had its origins in an earlier project which showed that crash rates increased at extremes of horizontal and vertical geometry, and were lowest with narrow sealed shoulders. This paper reports an investigation based on the original…

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…
