Pavements

Cooperative Agreement Materials

The Federal Highway Administration (FHWA) has an ongoing Accelerated Implementation and Deployment of Pavement Technologies (AIDPT) Program, which includes the deployment of innovative technologies to improve pavement performance and reduce agency risk. A constant challenge in the transportation community is timely and efficient deployment of these new and innovative technologies. The purpose of this cooperative agreement is to stimulate, facilitate, and expedite the deployment and rapid adoption of new and innovative technology relating to the design, production, testing, control, construction, and investigation of asphalt pavements.

FHWA documents are identified with an FHWA report number (e.g., FHWA-HIF-23-032). Cooperative agreement materials are identified as “Cooperative Agreement Material.” More information about the cooperative agreement is at: https://www.unr.edu/wrsc/tools/asphalt. This material is disseminated under the sponsorship of the U.S. Department of Transportation in the interest of information exchange under agreement number 693JJ31850010 Development and Deployment of Innovative Asphalt Pavement Technologies. The U.S. Government assumes no liability for the use of the information in the non-FHWA-branded documents.
