Details

Intermediate temperature tests for modified binders may help capture the cracking resistance of these materials better than traditional methods. TRB hosted a webinar on Wednesday, May 25, 2022 from 2:30 PM to 4:00 PM Eastern that explored findings from these innovative tests, which use common asphalt binder laboratory equipment. Factors that can significantly affect the fatigue performance of asphalt pavements include the binder content, binder aging, and the chemical and physical characteristics of the asphalt binders used in the asphalt pavement layers. Continued funding for research in this area was also discussed.

This webinar was sponsored by the TRB Standing Technical Committee on Binders for Flexible Pavement.

The slides and recording are available. 

 

Webinar agenda and presenters

  • Measuring cracking resistance of modified and unmodified asphalt binders with a poker chip – Ramez Hajj, University of Illinois
  • A DSR-based extensional deformation (or force ductility) test to characterize modified binders at intermediate temperatures – N. “Wasi” Wasiuddin, Louisiana Tech University
  • State perspective on cracking resistance of modified binders – Enad Mahmoud, Texas Department of Transportation
  • Question and answer session – Amy Epps Martin, Texas A&M University

The first 60 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions.

 

Learning Objectives

At the end of this webinar, participants will be able to:

  • Use and apply emerging intermediate temperature tests to characterize the benefits of modified binders using existing laboratory equipment
