Advancing Pavement Surface Evaluation to Support Engineering and Investment Decisions
The American Association of State Highway and Transportation Officials (AASHTO's) Pavement Rutting and Cracking Quantification Expert Task Group (ETG) was formed in 2006 with Federal Highway Administration (FHWA) funding to provide program guidance and assistance in development and enhancement of standards for pavement rutting and asphalt pavement surface cracking. The ETG was formed with subject matter experts to represent AASHTO, FHWA, the American Society for Testing and Materials (ASTM) Committee E-17 on Vehicle-Pavement Systems, Transportation Research Board (TRB), the Long Term Pavement Performance (LTPP) Program, academia, and industry. Revised data collection and analysis protocols have been produced and evaluations are being initiated to identify how best to continue the development process.
