Cracking is a primary distress mode of asphalt pavements that creates the need for their rehabilitation. Laboratory testing is designed to evaluate cracking; however, an NCHRP report recommends revisions to all cracking test methods evaluated. TRB hosted a webinar on Monday, December 5, 2022 from 12:00 PM to 1:30 PM Eastern that presented the results of ruggedness testing of for the cracking resistance of asphalt mixes. Presenters highlighted eight laboratory tests and revisions to the test methods. The webinar is of interest to engineers in state and local transportation agencies and in industry with responsibility for evaluating the performance of asphalt mixes. Testing methods for all types of asphalt pavement cracking—thermal, reflection, fatigue, and topdown— were explored.

This webinar is based on NCHRP Report 987 Ruggedness of Laboratory Tests for Asphalt Mixture Cracking Resistance.

This webinar was sponsored by TRB’s National Cooperative Highway Research Program.

The slides are available. Please contact for a link to the recording. There may be a $90 fee.


Webinar agenda and presenters

  • Ruggedness of laboratory tests for asphalt mixture cracking resistance – Fujie Zhou, Texas A&M Transportation
  • Cracking tests and balanced mix design – Casey Nash, Maine Department of Transportation 
  • Question and answer session moderated by Tom Bennert, Rutgers 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:

  • Make informed decisions about implementing new research to ruggedness issues of cracking tests
