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,…

Guide to Pavement Technology Part 4K: Selection and Design of Sprayed Seals is a guide to the procedures for the selection and design of sprayed seals. This is an update of previous Austroads procedures based on the philosophy of filling up voids in…

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 webinar, presented on 22 August 2019, provides an overview of the key changes to the Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design and the significant advances in the thickness design of structural treatments for…

The Australian polymer modified binder (PMB) specification (AGPT/T190) currently requires different binder grades to be used in sprayed sealing and asphalt applications. This study compared the sprayed seal performance of PMBs representing four AGPT/…

The use of stabilisation technology for stabilising and recycling materials for pavement construction and maintenance is widely accepted as a cost-effective method of improving long‑term performance and reducing whole-of-life costs of modern,…

This webinar, presented on 11 April 2019, gives an overview of the key changes to the Guide and the significant advances in the areas of stabilisation or road pavements.

This Pavement Work Tip details the profiling or cold planning of asphalt pavements, a process that removes uneven areas of pavement to allow the placement of  new, uniform surface.
