An analysis of heavy traffic loadings on the Illinois Interstate Highway system was conducted. Volumes and weights of single and multiple unit trucks were determined and converted to cumulated 18-Kip equivalent single axle loads (ESAL) for every construction section over the period 1956 to 1986. Results show that the Interstate highway pavements have been subjected to far greater traffic loadings than which they were designed. The traffic data have been input into the Illinois Pavement Feedback Database for use by agency personnel. It is recommended that improved estimating procedures be developed for 18-Kip ESAL's to be used for future pavement design and rehabilitation purposes.
