摘要：	The deteriorating condition of paved road networks and the limited resources available for rehabilitating these roads are challenging highway administrators and managers in both developing and developed countries. Research conducted in Brazil allowed the development of performance prediction models for pavement roughness, raveling, potholing, rutting, and cracking as a function of significant variables that define pavement structure, environment, and traffic loads. These models were incorporated into a microcomputer program that generates alternative rehabilitation strategies, predicts the performance of each strategy that meets the allowable criteria, and produces a set of the five best feasible strategies according to the predicted total cost. Presentation of the analysis package and demonstration of its application are achieved by discussion of the background, rationale, and summary of the performance models; a brief review of the structure of the package; and presentation of a case study. This method of analysis can be used as a project-level pavement management tool compatible with the needs of low- to medium-volume road links in tropical and subtropical environments or for evaluating a network of roads requiring rehabilitation. For applications at the network level, a key feature is its full compatibility with the Expenditure Budgeting Model (EBM), which means that its output can be used as input to EBM to address the budgetary-constraint problem.
