The Illinois Interstate system consists of about 1750 miles of 10-inch jointed reinforced concrete pavement (JRCP) and continuously reinforced concrete pavement (CRCP) ranging in thickness from 7 to 10 inches. As of 1991, about 60 percent of these pavements had been overlaid with asphalt concrete (AC), ranging in thickness from 1.5 to 6 inches. Data for the survival analysis were retrieved from the Illinois Pavement Feedback System database. Both in-service life and accumulated 18-kip ESALs at rehabilitation were estimated for bare pavements categorized by type, thickness, and D cracking susceptibility, and for overlaid pavements categorized by overlay thickness, overlaid pavements type, and D cracking susceptibility. The results show the effects of D cracking, traffic level, pavement type, pavement thickness, and ovelay thickness on performance of bare and resurfaced concrete pavements.
