This emulsion specification database was developed by the Asphalt Institute. Available below (as downloadable pdf files) are individual documents for each of the 50 state highway agencies which summarize their respective asphalt emulsion specifications. A standardized format is used to list the testing requirements for the emulsion grades listed in that State’s specifications. Different Tables are utilized that reflect the different categories of emulsions used in that State. Notes are included for additional details. Other information includes the State website where the specifications can be found and the State Contact.
All specifications are in Adobe PDF format
AI will periodically contact the Materials Engineer listed on each document to review the agency’s information for accuracy. Corrections or comments may be e-mailed to us by using the link below. Changes will only be made after confirmation by the individual listed for that agency.
While care has been taken to provide the most accurate and current information, users are warned that there may be inaccuracies and recent specification revisions may not be reflected. To ensure the most accurate information, the particular agency should be contacted. In addition, this compilation of information should not infer an Asphalt Institute endorsement for any of the specifications or requirements listed.
