N2 - One of the innovative approaches for maintaining and rehabilitating the nation's highways is to develop and implement some form of pavement management system (PMS). This paper documents results of a survey on PMS use in the United States. In addition, a simple method for a PMS based on priority ranking is presented. The model uses the theory of fuzzy sets to process the information obtained from a typical pavement condition survey. An index, called unified pavement distress index (UPDI), is defined and used to measure the pavement distress condition. The new approach is presented in a few key elements: guidelines for rating of six types of distresses, weights among the different types of distresses, fuzzy-set representations of the linguistic grades and fuzzy mathematics, and the definition of UPDI and its use in a pavement data base. An example is presented to show how the new approach can be employed to analyze data bases generated from a pavement condition survey. While the proposed approach has shown its potential in the example application, more positive feedbacks from large-scale field tests are needed to demonstrate its reliability and ease of use.
