Intermediate temperature tests for modified binders may help capture the cracking resistance of these materials better than traditional methods. TRB will host a webinar on Wednesday, May 25, 2022 from 2:30PM-4:00 PM Eastern that will explore 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 will also be discussed.


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


Registration is free for employees of TRB sponsors as well as Titanium and Cobalt Global Affiliates. The registration rate for all other attendees is $100. Sign into to view registration information. Contact Patrice Davenport to inquire about becoming a TRB sponsor or global affiliate organization.


A recording will be sent to all registrants after the webinar.


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


Professional Development Hour Information


Professional engineers (PEs) who register and attend the entire webinar as an individual will be awarded 1.5 Professional Development Hours (PDHs). TRB’s webinar program awards PDH credits only to the registered individual, and not to other members of a group that view the webinar together. To be eligible for the credits, individuals must remain signed in for the entire webinar, including for any question and answer session following the presentations.


Please check with your licensing board to ensure that TRB webinar PDHs are approved by your board.


TRB will report credits earned to the Registered Continuing Education Program (RCEP). Complaints about registered providers may be sent to RCEP, 1015 15th Street, NW, 8th Floor, Washington, D.C., 20005.


Pre-registration is required. Once the webinar starts, you will be unable to register. Individuals that are registered for a webinar but do not receive their confirmation emails due to their organization’s internal firewalls should contact the TRB Helpdesk for assistance in signing in.
