Book excerpt: In previous studies, the performance of bare and resurfaced jointed reinforced concrete pavement (JRCP) and continuously reinforced concrete pavement (CRCP) on the Illinois freeway system was assessed by survival analyses. In this study, the 1994 data have been used to update the survival analysis of JRCP and CRCP and to carry out an initial survival analysis on the full depth asphalt sections (HMAC) of the Illinois freeway system. First and second asphalt concrete (AC) overlays were analyzed separately. Data for the survival analysis were retrieved from the Illinois Pavement Feedback System (IPFS) database. The Illinois freeway system consists of over 2,000 centerline miles (3,218 km) of heavily trafficked multiple-lane pavements which were constructed largely between 1957 and 1994. As of 1994, about 32% of these pavements had been overlaid once with AC ranging in thickness from 1.5 to 7.0 in. (3.8 to 17.8 cm). About 26% of these have been overlaid for the second time with AC ranging in thickness from 1.5 to 7 in. (3.8 to 17.8 cm).
