LTPP's analysis program takes the raw data that is collected from the program's more than 2,400 pavement test sections and converts it into useable information. The program addresses a broad array of topics – from field validation of pavement design procedures, to studies of variability in traffic and materials data, to investigation of the development of pavement roughness. Some analysis findings have led to the development of products, such as Rigid Pavement Design software and LTPPBind. All analysis findings, however, provide valuable insight and direction to guide future LTPP data collection and analysis efforts.
Since 1999, the National Level analysis of the LTPP data has been guided by the Strategic Plan for Long–Term Pavement Performance Data Analysis (the Strategic Plan). The Strategic Plan was developed by the TRB Expert Task Group on LTPP Data Analysis, recommended by the TRB LTPP Committee and adopted by the FHWA as the basis for selecting LTPP analysis projects and evaluating progress in LTPP data analysis.

In 2003, FHWA leadership accepted the challenge to "raise the bar" on R&T and adopted a strategic management framework developed with input from stakeholders. See Corporate Master Plan (CMP) for Research and Deployment of Technology & Innovation (FHWA-RD-03-077)
