Abstract:This report summarizes the activities and accomplishments of the Long-Term Pavement Performance (LTPP) program Materials Action Plan (MAP). The MAP was initiated in August 2004 to improve the extent and amount of materials data to characterize the pavement structure of test sections at LTPP Specific Pavement Study (SPS) -1, -2, -5, -6, and -8 experimental sites. The success of the MAP can be attributed to the cooperation and efforts of participating highway agencies, leadership of the Federal Highway Administration (FHWA) LTPP team, and technical input from LTPP’s Transportation Research Board Committee and Expert Task Groups. The MAP was also supported by the efforts of the FHWA LTPP team of technical services, regional support, and laboratory contractors. Through this effort, the amount and quality of available materials data greatly increased. Data from tests not previously performed were added, results from aging materials tests were obtained, corrections were made to some pavement structure information from new field investigations, and to the extent possible, previous data deficiencies were corrected. This report documents the planning, execution, and outcomes of this highly successful activity.
