TRB conducted a webinar on Thursday, October 6, 2016 from 2:00PM to 3:30PM ET that discusses the performance grading system for hot-poured crack sealants. Crack sealants can be a cost-effective preventative maintenance method for pavements. When properly installed, crack sealants can extend pavement service life for as many as five years. This webinar discussed research from two U.S. Federal Highway Administration (FHWA) pooled fund studies on the development and validation of performance-based sealant guidelines. Preliminary results are documented and published in the Transportation Research Record: Journal of the Transportation Research Board. The results of the first study were the focus of a
TRB webinar on October 23, 2012. Contact Reggie Gillum at
RGillum@nas.edu for instructions on receiving a copy of the recorded webinar.
This webinar was requested by the TRB Standing Committee on Sealants and Fillers for Joints and Cracks. A certificate for 1.5 Professional Development Hours (PDHs) was provided to attendees who register and attend the webinar as an individual.
