TRB Webinar: Open Graded Pavements: A Primer with Emphasis on Water Quality Benefits

Pavement designers are invited to a TRB webinar on Thursday, September 19, 2019, from 2:00 PM to 3:30 PM ET. This webinar will describe open graded pavement designs for highways, including Permeable Friction Course (PFC) overlays. These overlays are thin-lift open-graded pavement sections placed over a conventional highway pavement section that are used to reduce noise, enhance traction during wet weather, and improve visibility. PFCs also have the potential to improve runoff water quality from highways....
