Austroads Technical Specification ATS 3480 sets out the requirements for the following treatments to the surface of bituminous pavements: improving the surface texture of sprayed seals by removing excess binder (&lsquo

The improved use of locally available materials in road construction and maintenance can significantly reduce costs, particularly in rural and remote areas and for low-volume traffic roads. This webinar provides an overview of the key components…

This report documents the findings of an Austroads project which aims to encourage sustainable roads through fit-for-purpose use of available materials. The research addressed the use of marginal and non-standard materials in both sealed and…

This webinar, presented on 17 February 2020, provides an overview of the life cycle management of local sealed and unsealed  roads. It highlights the Austroads Guides and the AUS-SPEC national local government specification system which assist local…

This study investigated the relationship between cutter oil properties and sprayed seal performance so that this information could be used as a basis for updating Australian Standard 3568. AS 3568 specifies the properties of four different types of…

Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design provides advice for the investigation of existing sealed road pavements and the selection and design of pavement strategies/treatments. It covers pavement investigation,…

This report examines the viability of using recycled plastics in asphalt and sprayed seals by Australian and New Zealand road authorities. The report presents the findings of a literature review, including case studies of local and overseas road…

New methods of using pavement deflection data were developed in the context of pavement structural rehabilitation treatment design. The project focused on two main components. The first was to assess the potential use of traffic speed deflectometer…

This report presents the results of a field validation study conducted as part of the development of a new long term ageing test for polymer modified binders used in sprayed seals in Australia. Unaged samples of binders were collected during the…

This document sets out the performance requirements expected of bitumen sprayers operating in Australia and New Zealand.

For a consistent and high quality of sprayed sealing work to be undertaken, and for sprayed sealing to remain a viable surfacing…
