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 is an update of earlier Austroads sprayed seal design procedures based on the philosophy of filling voids in the aggregate matrix with binder to a depth of about one half to two thirds the height of the aggregate when laying on its least…

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…

Austroads has produced a series of test methods developed from various technical projects, principally in the bituminous materials area (asphalt, binders, slurry and sprayed seals). The Austroads system of managing the test methods has enabled…

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…

An Austroads national workshop on sprayed sealing was held to assist development of a research program and identify challenges to the future use of seals. Delegates identified key issues under the themes of: safety and traffic management

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).…
