摘要：	Current methodologies for developing, evaluating, and improving long-range rehabilitation programs may be classified as manual or analytical. The major limitation of manual methods is that although they are practical, they are not cost-effective because of the difficulties of comparing potential cost/benefit trade-offs among alternatives. Analytical methods, on the other hand, are more cost-effective but often not practical, because they oversimplify the real problem into a mathematical model and do not allow engineers and managers to be involved in the decision-making process. A new methodology and new concepts to overcome these major deficiencies were developed and implemented. The first of the new concepts is the use of graphical data interpretation and "visual thinking". The second is that pavement performance evaluation should be comprehensive and quickly accessible. The third is that human knowledge should be involved in the decision-making process through a user-friendly interface. The fourth is that the relationships among the components of the methodology should be flexible rather than rigid. Finally, the process should be efficiently repeatable so that a satisfactory long-term rehabilitation program can be developed. A user-friendly, Windows-based pavement management system, called Windows ILLINET, was produced in this study on the basis of the new methodology and concepts.
