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 report considers the issues and possibilities of a data framework, incorporating road use data and network performance data, that could apply for all road authorities and provides guidance on a way forward, taking into account the current…

The report considers the issues of pricing, partnerships and accessibility in relation to road use data, traffic and network performance data. The aim of this report is to provide information on industry practices and inform the discussion on…

This report addresses the issue of calculating ESA-km in the road maintenance funding formula of AusLink This study recommends the use of an average ESA per heavy vehicle class in the funding formula This requires each jurisdiction to prepare from…

This document reports the results of an Austroads scoping study to formulate an approach to improve the collection, transformation and sharing freight data between jurisdictions, agencies and companies. The study is designed to inform development of…

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).…
