This report presents the results of a study to plan for updating and maintaining the rigid pavement condition survey database for the Texas Department of Transportation (TxDOT). These data will be used to develop performance prediction models for rigid pavements (continuously reinforced concrete, jointed reinforced concrete and jointed plain concrete pavements) in Texas. These models will be developed for the Texas Department of Transportation for future incorporation into the Texas Pavement Management Information System (PMIS). The data collected in this project and in future projects will be combined with data collected from Project 472, which are summarized in the references, to provide improved long-term performance prediction capability.
The rigid pavement (RP) database contains historical distress data obtained from more than 400 continuously reinforced concrete pavements (CRCP) and jointed concrete pavements (JCP) across the state of Texas. Data collection efforts began in 1974 and have been undertaken periodically up to the present. The database contents include such performance-related variables as punchouts, patches, spalling, ride score, crack spacing, and deflection basins, as well as such inventory variables as location, design thickness, coarse aggregate type, climate, soil characteristics, date of construction, and overlay status. Taken as a whole, the RP database comprises a unique asset for empirical investigation of factors affecting long-term pavement performance in Texas.
