Abstract
The Indiana DOT is significantly revising asphalt binder specifications that will impact all contracts as early as 2024. The base asphalt binder grade in Indiana is changing from PG 64-22 to PG 58-28 and the testing requirements for all asphalt binders will change from PG binder testing to MSCR and percent recovery. This session will provide the background, overview, and expectations needed for pavement designers, consultants, contractors, DOT, and local agency personnel to understand.
