THE USE OF FUZZY SETS MATHEMATICS IN PAVEMENT EVALUATION AND MANAGEMENT. EXECUTIVE SUMMARY

A methodology has been created for ranking pavement sections according to maintenance urgency using fuzzy sets mathematics to account for human and system uncertainty in the pavement management system. Fuzzy sets are used to represent the subjectivity in pavement serviceability ratings and distress surveys, and the variability in Roadmeter, Skid-tester and Dynaflect readings. Techniques are presented for correlation of fuzzy numbers to create the Pavement Serviceability Index. Initial grouping of pavement sections compares the PSI with an Acceptable Serviceability Level and an Unacceptable Serviceability Level, both of which are subjective opinions obtained from experts. The final ranking is formulated using fuzzy multi-attribute decision-making concepts using an expert knowledge base. This information is obtained from decision makers for known attribute value combinations using suitable questionnaires. The result is a unique ranking of pavement sections according to maintenance urgency. (Author) pavement sections according to maintenance urgency. (Author)
