TRB Webinar: Laboratory Methods and Specifications for Testing Tack Coat Materials

December 17, 2024

1:00 PM - 2:30 PM (EST)

Past

Topics

Tack coat specifications can promote long-term pavement performance and reduce issues like slippage and delamination between layers. TRB will host a webinar on Tuesday, December 17, 2024 from 1:00 PM to 2:30 PM Eastern that provided an overview of NCHRP Web-Only Document 381: Developing Laboratory Methods and Specification Language to Test Tack Coat Materials, highlighting key findings from the study, including recommended changes to tack coat material specifications. Presenters covered the evaluation plan for tack coat materials and a field experiment designed to validate the proposed specifications.

This webinar was sponsored by TRB’s National Cooperative Highway Research Program and the Standing Technical Committees on Production and Use of Asphalt Mixtures and Asphalt Pavement Construction and Rehabilitation.

The slides are available. Please contact trbwebinar@nas.edu for a link to the recording. There may be a $90 fee.
