AI and PRI debut new state binder specification database

The Asphalt Institute and PRI Asphalt Technologies have collaborated to develop a new state binder specification database. Each individual specifications document (available as a downloadable PDF file) summarizes the respective asphalt binder specifications for each of the 50 state highway agencies. A few additional agencies are also provided.

A standardized format is used to list specification methods and criteria, PG-plus tests and requirements, typical grades, exclusions, and the agency?s website where specifications can be found.

AI and PRI will periodically contact the Binder or Materials Engineer listed on each document to review the agency’s information for accuracy. Corrections or comments may be e-mailed to AI by using the form provided at the link below. Changes will only be made after confirmation by the individual listed for that agency.
