摘要：	The Pavement Performance Modeling Program (PPMP) developed for the Pennsylvania Department of Transportation by Texas Research and Development Foundation is described. PPMP is a MicroSoft Windows-based computer tool to assist engineers in developing pavement performance models for use in pavement management systems and updating these models annually as new data are input into the data base. The program can build both deterministic models and probabilistic models for an individual or group of pavement segments for each maintenance and rehabilitation (M&R) treatment. The program allows the user to define pavement performance indexes, grouping variables, and M&R treatments. Grouping variables are those that influence performance and are thus accounted for in the analysis. They include annual average daily traffic or equivalent single axle load (ESAL), functional class, pavement structure depth, maintenance level, and others at the discretion of the user. For deterministic models, five forms of equations are included. The independent variables can be pavement age or ESAL. Data and models can be plotted on screen and analyzed. The results from sample runs are presented and discussed.
