Concrete overlays of asphalt (COA) pavements are a widely accepted rehabilitation strategy used to extend the life of asphalt pavements. However, there are still design and construction challenges, and COA features often differ between states. TRB will host a webinar on Thursday, March 11, 2021 from 2:00-3:30 PM Eastern that will provide an overview of recently completed COA research and field implementations. Presenters will identify research from Accelerated Pavement Testing and long-term performance studies. They will also discuss case studies to highlight essential factors for states looking to implement or improve upon this strategy.

This webinar is sponsored by the TRB Standing Committee on Pavement Structural Testing and Evaluation.

Some registrants will need to pay $95 to attend this webinar. Sign into MyTRB.org to view registration information.
