70:(AASHTO) sponsored the program. The program was focusing on examining the deterioration of the nation’s highway and bridge infrastructure system. In the early 1980s, TRB and NRC suggested that a "Strategic Highway Research Program (SHRP)" should be started to concentrate on research and development activities that would majorly contribute to highway transportation improvement. Later in 1986, the detailed programs were published entitled "Strategic Highway Research Program—Research Plans".

The LTPP program collects data from in-service roads and analyzes it as planned by the SHRP. The LTPP aims to understand the possible reasons behind the poor or good performance of pavements. Hence, the effects of different parameters such as weather, maintenance actions, material and traffic on
