The Transportation System Preservation Technical Services Program (TSP∙2) was initiated as an efficient means to disseminate information to AASHTO member agencies for preserving their highway infrastructure, including both pavements and bridges. Its principal mission is to serve as a clearinghouse with comprehensive and up-to-date information on efficient and effective preservation measures that enhance highway performance and extend useful life.
