TRB Webinar: Guide Specifications—Constructing Slurry Seals, Scrub Seals, and Tack Coats

April 19, 2023

2:30 PM - 4:00 PM (EDT)

Past

Topics

Slurry seals, scrub seals, and tack coats are a means to pavement preservation, extending service life, and overall performance. However, there is no nationally accepted guidance on their construction. TRB hosted a webinar on Wednesday, April 19, 2023 from 2:30 PM to 4:00 PM Eastern that presented findings from a recent study and construction guide specifications that have been developed to help agencies fill gaps in existing construction specifications. The construction guides shared by the presenters are currently in review by the AASHTO Committee on Materials and Pavements at the time of this webinar.

This webinar is based on NCHRP Project 14-44: Guide Specifications for the Construction of Slurry Seals, Scrub Seals, and Tack Coats.

This webinar was sponsored by TRB’s National Cooperative Highway Research Program and the Standing Technical Committee on Pavement Preservation.

The slides are linked in the meeting materials. View the recorded webinar below.
