The objective of this research is to support Federal Highway Administration (FHWA) by advancing the current knowledge and state-of-the-practice in the sciences and technologies utilized in the planning, design, construction, operation, maintenance and management of the porous-graded asphalt (PGA) used in the Nations highways. This will require synthesizing relevant information available and building upon that information to develop and carry out a research and implementation plan. Strategically, this research will enable and expedite the development and deployment of PGA which will greatly improve the safety and efficiency of highway transportation.
