As of 2008, 33% of roads in the U.S. are unpaved or unsurfaced, and evaluating these roads requires a different perspective than evaluating asphalt or concrete roads. TRB will host a webinar on Wednesday, August 25, 2021 from 1:00-2:30 PM Eastern that will present two methodologies for unsurfaced road evaluation and rating. One is the unsurfaced road condition index (URCI) developed by the U.S. Army Corps of Engineers. The other is the gravel pavement surface evaluation and rating (PASER) method developed by the Transportation Information Center at the University of Wisconsin. The webinar can help municipalities and other agencies rate their roads to help establish budgets, make timely repairs, and set up cost effective maintenance procedures.

This webinar was organized by TRB's Standing Technical Committee on Aggregates.

Some registrants will need to pay $55 to attend this webinar. Sign into to view registration information.
