This report documents the development of a life-cycle cost procedure and program for project-level pavements. Included in this report are the descriptions of the models that are included in the computer program. A traffic growth model is described along with performance models for asphaltic concrete pavements and Portland cement pavements. The program calculates when rehabilitation is predicted at all future dates during the design life or analysis period. Recommended overlay thicknesses are also given. Because maintenance costs for Kentucky are not available, maintenance is treated as an annual, per square- yard quantity. User costs, in the form of a delay model are also presented. All future costs are calculated in terms of present worth.

A users manual is also included in the report. Appendix D is a listing of the source code for the computer program.
