Paper by MOBSENI DARTER HALL from ISCR 6th 1990
The Illinois interstate highway network includes over 1700 centerline miles of jointed concrete and continuously reinforced concrete pavements. The pavements were constructed beginning in the 1950's through the 1980's and represent a wide range in designs and traffic loadings. This large highway network is now requiring extensive rehabilitation work as many of the pavements have reached their design life of 20 years, and have carried over 3 times their design traffic. A comprehensive pavement management system (called ILLINET) has been developed for the Illinois Department of Transportation to assist in the programming of optimal rehabilitation strategies. The ILLINET system has been programmed to run on a personal computer and is very flexible and user friendly.
