Two previous studies on the survival of bare and asphalt-overlaid concrete pavements on the Illinois Interstate highway system were updated to reflect the performance of the pavements through 1991. The Illinois Interstate system consists of about 1750 miles of 10-inch jointed reinforced concrete pavement ORCP) 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 pavement type, and D cracking susceptibility. The results show the effects of D cracking, traffic level, pavement type, pavement thickness, and overlay thickness on performance of bare and resurfaced concrete pavements.

The Illinois Interstate highway network is deteriorating rapidly due to its age and heavy truck loadings. Unfortunately, the funds required for rehabilitation far exceed the available funds. The Illinois Department of Transportation (IDOT) faces many difficult decisions concerning prioritizing rehabilitation projects and anticipating future pavement conditions and rehabilitation needs. To assist IDOT in making these decisions, three analyses were conducted using the ILLINET pavement network rehabilitation management program. The first of these was an analysis of the accuracy of ILLINET' s pavement condition prediction models. The second was an analysis of the remaining life of each of the more than 1200 pavement sections in the Illinois Interstate network. The third was a comparison of the rehabilitation needs predicted by ILLINET to IDOT' s latest multi-year program. The results of these analyses are of immediate practical use to IDOT in forecasting pavement rehabilitation needs for individual pavement sections, Interstate routes, and the entire Interstate network.
