TRB will conduct a webinar on Monday, October 19, 2015, from 1:00PM-2:30PM ET about a study to assess the impact of new-generation wide-base tires (WBT) on pavements. This study was sponsored by the Federal Highway Administration, led by the University of Illinois, and presented at the 2012 TRB Annual Meeting. It will discuss a comprehensive approach, including experimental measurements, numerical modeling, and development of prediction tools. This webinar will summarize the methodology, results, and implementation of the study through suggested modification for the AASHTOWare Pavement ME Design software. In addition, the life-cycle assessment of wide-base tires will be presented.
