The fatigue performance of asphalt pavements is commonly blamed on structural design. TRB will host a webinar on Thursday, July 8, 2021 from 1:00-2:30 PM Eastern that will discuss research findings related to asphalt fatigue, durability, and aging. Presenters will also explore other factors, including the binder content, binder aging, and the chemical and physical characteristics of the asphalt binders used in the asphalt pavement layers. They will discuss cover asphalt binder aging during mixture production and the service life of the pavement. Changes to the current performance-graded asphalt binder specifications, tests, and practices may address issues related to the premature loss of asphalt pavement durability in the form of cracking and raveling. Active research shows that identifying, characterizing, and effectively specifying the properties may specify a binder that can improve the fatigue properties of the mixture. This webinar was organized by the TRB Standing Technical Committee on Binders for Flexible Pavement. It also features research from NCHRP Research Report 967: Asphalt Binder Aging Methods to Accurately Reflect Mixture Aging. Some registrants will need to pay $95 to attend this webinar.
