Abstract:

The Long-Term Pavement Performance (LTPP) database is the world’s premier source of data and information on pavement performance. However, understanding and using the database is not necessarily an easy undertaking. For starters, the data are typically distributed across multiple tables in the database, making some data elements hard to mine. There are also multiple values for a given data element, making it difficult to know which value(s) to use. In addition, the data may have to be further interpreted to present meaningful results. Because of these challenges, the LTPP program has undertaken a process to generate analysis-ready datasets (ARDs), starting with the dataset detailed in this document— Analysis Ready Materials Dataset (ARMAD) (FHWA 2015). The ARMAD solves the stated challenges for the layer thicknesses and material properties of all test sections in the LTPP database with one exception—the Specific Pavement Studies (SPS)-10 warm-mix asphalt experiment test sections. Testing for these SPS-10 test sections is presently ongoing, and the results will be incorporated upon completion. Similarly, future planned ARDs—climatic conditions, traffic conditions, and performance data—will be incorporated into upcoming Standard Data Releases (SDRs).
