AAPTP Update March 2007: Project Status and Future Developments in Airfield Pavement Research

The AAPTP program, initiated in 2004 through a cooperative agreement with Auburn University, focuses on advancing airfield pavement technology. As of March 2007, 12 projects have been awarded, with 1 in evaluation and funding available for 7 new projects. Recent statuses indicate ongoing work on rubblization and superpave projects with projected completion in 2007. New projects for FY-07 aim to improve shear strength, mix design, and evaluate mechanisms of pavement failure. A comprehensive update on funding and project status is provided, ensuring continuous enhancement in airfield pavement research.
