The Long-Term Pavement Performance (LTPP) program has a wealth of materials information and data from almost every program test section, as well as from a well-structured laboratory materials testing program to further classify and characterize pavement layers.
 

Therefore, the program developed a process to generate LTPP Analysis-Ready Materials Dataset (ARMAD). This dataset summarizes the material properties for every layer in the database, which has the benefit of substantially reducing researchers’ time and making the data more accessible to all. The ARMAD dataset is now available on the LTPP InfoPave™ web portal (FHWA 2022a). This report provides the objectives, rationale, process, and results of the development of the ARMAD dataset and is useful to transportation agencies, consultants, and researchers who will use ARMAD to exploit LTPP data to gain knowledge into the how and why of pavement performance, which is the primary goal of the LTPP program.
