Webinar: Technical Basis of Changes to Guide to Pavement Technology
Austroads has published two technical reports drawing together the research underpinning changes made to key components of the Guide to Pavement Technology. The reports detail the technical basis for changes made to 
Sprayed Sealing – Surface Enrichment
This Pavement Work Tip provides a guide to the light application of bituminous binder to an existing asphalt or spray seal surface to increase the binder level on the surface and prevent aggregate loss.
Technical Basis of Austroads Guide to Pavement Technology Part 2: Pavement Structural Design
This report documents the technical basis of the 2010, 2012 and 2017 editions of Austroads&rsquo
Webinar: Outcomes from the Long-Term Monitoring of Austroads Sprayed Seal Trials
Flexible granular pavements protected by sprayed seal surfacings are the backbone of the Australian and New Zealand road networks. Road agencies in Australia and New Zealand have therefore been focused on producing quality, long-lasting sprayed seal…
Webinar: Harmonisation of Measurement and Mass Assessment Procedures for Special Purpose Vehicles in Australasia
Within Australia and New Zealand, the processes, procedures and reporting of mass and dimensions of Special Purpose Vehicles (SPVs) differs significantly depending on the jurisdiction where the measurements take place. Austroads&rsquo
Inspections of Polymer Modified Binder Trial Sites and Ageing Properties of Binders
This report presents the findings of site inspections and binder ageing performance studies associated with two Austroads sprayed seal trial sites constructed near Coober Pedy, South Australia and Cooma, New South Wales. These trials were…
Harmonisation of Measurement and Mass Assessment Procedures for Special Purpose Vehicles in Australasia
Within Australasia Special Purpose Vehicles (SPVs), also known as mobile plant in New Zealand, are routinely measured and weighed differently depending on the jurisdiction completing the measuring and weighing. The objective of this research is to…
Webinar: Standards Australia – Bitumen and Related Materials for Roads
This webinar, presented by Robert Urquhart on 11 August 2020, gives an overview of an Austroads project which provided expert technical input into the update of four Australian standards which were revised by the Standards Australia Technical…
Bituminous Surface Retexturing
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
Relationships Between Cutter Oil Properties and Sprayed Seal Performance
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…
