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. |
