This report investigates policy options for reducing the harmful effects of the oldest trucks operating on Australian and New Zealand roads. Aged trucks impose a financial burden on the community through their effects on human health and the…

This report investigates the origins of the current Unconfined Compressive Strength (UCS) criteria that differentiates modified granular materials from bound materials. Based on the review, a number of changes to the UCS design criteria are…

Over the last decade a considerable amount of research effort has been focussed on the development of a repeated load triaxial (RLT) test procedure to assist practitioners in the use of natural and marginal unbound base/subbase materials in road…

This report describes the perceived impact of heavy freight vehicles using major freight routes on people living or working close to such routes. The literature obtained, and the experience of relevant stakeholders, suggested that noise and…

It is predicted that the Australian road freight task will more than double between 2000 and 2020. The Australian heavy vehicle industry estimates that the increased road freight task will result in the addition of approximately 50,000 trucks to the…

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…

The Austroads project T+E.E.531 was undertaken to determine to the state of the art in regional and local air quality modelling within Australia as applied to road transport projects and to provide recommendations for the way forward to address…

This technical report resulted from a study to develop Austroads guidelines on network level assessment and analysis of data on pavement structural condition. This report outlines the benefits of network level assessment of the structural condition,…

The principle objective of air quality impact assessment is to give the community an acceptable assessment of the air quality changes brought about through a significant road project. The initial in-house scoping of a significant road project,…

The Review of Vertical Exhausts report concludes that vertical exhaust stacks on heavy vehicles result in dramatically improved air quality and only slightly higher noise levels compared to conventional low exit exhaust systems in an urban…
