Development of a Sprayed Seal Binder Cracking Test

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.
