The Asphalt Institute and the Association of Asphalt Paving Technologists are teaming up to present a series of webinars addressing fatigue cracking of asphalt pavements.

Registration is open now for the three webinar sessions. The first session is Thursday, October 20th at noon E.S.T. The second session is Thursday, October 27th at noon E.S.T. The final session is Thursday, November 3rd at noon E.S.T. Each session will last one hour.

The instructors for the sessions are Dr. Andrew Braham, PhD, P.E. of the University of Arkansas and Dr Shane Underwood, PhD of Arizona State University. R. Michael Anderson, P.E. of the Asphalt Institute will serve as moderator for these sessions. The series is intended for user agency, asphalt industry and academia professionals interested in asphalt technology who want a better understanding about the characterization of fatigue cracking of asphalt materials using laboratory tests and analyses.

“Understanding how material selection and properties impact an asphalt mixture’s performance is a great first step towards minimizing the incidence of asphalt pavement cracking in service,” said Anderson.

The first session is an introduction that will cover theories on crack process as well as fracture mechanics, energy methods and healing. The second session deals with asphalt binder and mixture fatigue cracking tests. The third session will explore energy-inspired, continuum damage and fracture technique fatigue analysis.

Space is limited, so advanced registrations are encouraged. Visit for more information.
