Roundabouts are increasingly popular due to their enhanced traffic flow and safety characteristics. TRB hosted a webinar on Wednesday, November 17, 2021 that will address the pavement aspects of designing and constructing roundabouts. Presenters will discuss designing roundabouts with conventional pavement types, such as hot-mixed asphalt (HMAP) and jointed concrete pavements (JCP).

This webinar is sponsored by the TRB Standing Technical Committees on Roundabouts and Other Intersection Design and Control Strategies, as well as Design and Rehabilitation of Concrete Pavements, and Project Delivery Methods.

The slides and recording are available.
