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 will provide 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 will cover the evaluation plan for tack coat materials and a field experiment designed to validate the proposed specifications.
This webinar is 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.
Registration is free for employees of TRB sponsors as well as Titanium and Cobalt Global Affiliates. The registration rate for all other attendees is $100.
