The American Association of State Highway and Transportation Officials (AASHTO) in conjunction with NTPEP have developed a process for the evaluation of production data and field performance data for reinforcement geosynthetics. The data generated by NTPEP is valuable for State DOT’s and other regulatory agencies to develop and maintain Qualified Products Listings (QPL). As of 2011, an audit phase has been added to the evaluation process in order to verify the consistency of the geosynthetic reinforcement in accordance with the REGEO work plan.
