Application of PSCP 3.0 Program to Predict Stresses in Prestressed Concrete Pavements

Prestressed concrete pavements have proved to be extremely cost efficient, to require less maintenance compared with other pavement types, and are now being widely used for both highways and airport runways. In prior research relating to prestressed concrete pavements, the various parameters that are significant in the design of these pavements have been isolated and their effects modeled to predict the resulting stresses and displacements in the pavement slab. This report summarizes an effort to improve the analysis and consequently the design of prestressed concrete pavements. The computer program developed in this study predicts the stresses and displacements in a prestressed pavement slab caused by environmental conditions and wheel loads. The information obtained from the computer program can be used in design to determine the slab thickness, prestress level, and length of slab, so as to keep the resulting stresses under allowable limits. A graphical user interface has been provided for the program for ease of use and better organization of the results obtained. This report gives a detailed account of the changes made to the previous version of PSCP computer program and a listing of the new program and the interface.
