Viability of Using Recycled Plastics in Asphalt and Sprayed Sealing Applications
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…
Properties of General-purpose Cement with Increased Percentages of Limestone
This report presents the results of a research project commissioned by Austroads to investigate whether the currently used Australian general-purpose (GP) cement which complies with AS 3972, and which may contain up to 7.5% limestone as a mineral…
Improved Methods of Using Pavement Deflection Data in the Design of Rehabilitation Treatments
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…
Infrastructure Changes to Support Automated Vehicles on Rural and Metropolitan Highways and Freeways: Audit Specification (Module 1)
By 2025, it is predicted that most new vehicles will be equipped with systems that can read traffic lines and signs. The purpose of this project (FSP6088) is to identify areas of current physical and digital road infrastructure on key highways and…
Infrastructure Changes to Support Automated Vehicles on Rural and Metropolitan Highways and Freeways: Road Audit (Module 2)
This project undertook an extensive field audit of Australian and New Zealand freeways and highways to inform the assessment of their readiness for active safety systems and automated driving.The road audit included more than 8 million individual…
Accelerated Long-term Ageing Methods for Sprayed Sealing Binders: A Field Validation Study
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…

  • AP-T262-19 Edition: 2.0
  • 12 Sep 2019
  • Pavement

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…

Performance of Asphalt and Spray Grade PMBs in Sprayed Seals
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/…
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…
Fire Incident and Fire Safety Operational Data for Major Australian Road Tunnels
This report sets out the process though which fire incident and fire safety operational information was collected for eleven major road tunnels in Australia. This tunnel data set are the major tunnels in Australia as defined by physical…
