Advancements in materials and application methods have affected tack coat bonding, durability, and performance over time. To help members of the asphalt industry select the right tack coat for a particular pavement, the National Highway Cooperative Research Program (NCHRP) published NCHRP Web-Only Document 381: Developing Laboratory Methods and Specification Language to Test Tack Coat Materials.
To discuss the publication’s findings, the Transportation Research Board will host a webinar on December 17 from 1 p.m. – 2:30 p.m. Eastern.
