Development of a Sprayed Seal Binder Cracking Test

Watch Now:

This webinar provides an overview of an Austroads project that developed a new sprayed seal binder cracking test and compared the performance of polymer modified binders (PMBs).

It covers:

  • background of the project
  • sprayed seal binder cracking test
  • comparisons of the performance of S20E/A20E and S25E/A15E grade PMBs in asphalt and sprayed seals
  • proposed changes to AGPT/T190 based on the results of the project.

The webinar was presented on 8 August 2019 by Robert Urquhart.

Road Risk Assessment, Case Studies and Engagement Guidance for Speed Management

Watch Now:

This webinar provides an overview of Infrastructure Risk Rating - a simple road assessment methodology designed to assess road safety risk at a network level, primarily as an input to the speed limit setting process.

It covers:

  • case studies demonstrating speed management interventions that were successfully applied in Australia and New Zealand
  • good practice guidance for engagement and consultation to effectively implement speed management interventions
  • the Infrastructure Risk Rating Tool which allows Infrastructure Risk Rating to be calculated for a road segment by selecting key road and roadside attributes
  • recommendations towards the implementation of the findings of the project.

The webinar was presented on 26 March 2019 by Haris Zia and Dale Harris.
