A rational design procedure was developed for composite concrete pavements based on fatigue damage considerations. The structural analysis of the composite system was performed using a finite element computer model developed at the University of Illinois. A curve was also developed using field data and a fatigue damage program to relate pavement cracking index to the fatigue damage value. This curve was developed to calibrate the procedure to actual field cracking conditions. It is an aid to the designer in selecting a fatigue damage value to use in the design of the pavement section for any allowable level of cracking. The example designs indicate that the composite pavement can be constructed at reasonable thicknesses with a potential reduction in total cement content. (Author)
