Longevity of Highway Pavements in Illinois-2000 Update
Results of the latest round of pavement longevity studies in Illinois provide updated performance data through 2000 for HMAC, JRCP, and CRCP new construction as well as AC overlays (first, second, and third overlays) of these original pavements. The Illinois Department of Transportation (IDOT) has periodically conducted pavement longevity studies to assess the longevity and load carrying capacity of these new and rehabilitated pavements so that any needed improvements to design, construction, or rehabilitation could be identified and implemented in a timely manner. These studies were conducted on over 2000 centerline miles of Interstate and other freeways that were constructed beginning in the 1950's in Illinois. Significant findings were obtained on the performance of the original pavements and overlays that will be of value to designers and administrators to improve pavement cost effectiveness and life. Key findings show the impact on longevity and load carrying capacity of pavement type (HMAC, JRCP, CRCP), slab thickness, geographic location (north or south), D-cracking, and AC overlay thickness (coupled with pre-overlay condition). The study also provides models for predicting the probability of survival for various designs of original pavements and AC overlays in Illinois for use in pavement management.
