Asphalt Program

The Asphalt Pavement Program provides timely and accurate asphalt mix and binder testing, ensure high quality of CDOT asphalt mix and binder testing statewide, and provide engineering and technical expertise in the development, selection, application, construction, testing and maintenance of asphalt mix and binder materials that will assist the Regions in the development of the Department’s transportation system to meet the surface condition goals established by the Transportation Commission.  The Asphalt Pavement Program consists of the Bituminous and European Laboratory, the Flexible Pavement Laboratory, Chemical Unit and the Asphalt Engineering Unit. The Program maintains an accredited laboratory in accordance with the AASHTO accreditation program (AAP). 

Products of this program include production and assurance testing of asphalt mix and binder and the development of mix design specifications and testing procedures.  They also include QA testing of asphalt binders and emulsions, development of specifications, including performance-graded binders, and testing of mixtures using European and performance testing methods.  In addition, specifications for Hot Mix Asphalt (HMA) and other asphalt mixtures are reviewed and developed.
