Abstract:

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 costeffectiveness ; 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.
