About LTPP Research
Since 1990, LTPP data has been used in hundreds of research analyses to study long-term pavement performance trends with the goal of enhancing pavement design and management practices. These research efforts have been guided by the Strategic Plan for LTPP Data Analysis which was first developed in 1999, and the plan has been routinely updated over the years. This plan categorizes the corresponding analysis efforts according to the identified research objectives and provides a list of completed, ongoing, planned, and proposed research projects in this regard. Funded through FHWA, NCHRP, or pooled fund projects, these analyses have resulted in significant advancements in pavement engineering and management. |
