FUZZY SETS TOOLS FOR EVALUATING THE ENVIRONMENTAL IMPACT ON PAVEMENT SERVICEABILITY

In this paper, the author advances a fuzzy set theoretic approach that enables the environmental present serviceability index (PSI) loss determination to be accomplished in a better defined and repeatable manner using the same AASHTO procedures. In this approach, the designer's qualitative descriptions of the relevant attributes are transformed to well defined fuzzy sets stored in the computer. At this stage of the development, fuzzy sets mathematics principles take over the manipulation process dictated by the AASHTO guidelines, to predict the PSI loss thus ensuring repeatability and consistency. The new technique is further illustrated by predicting the PSI loss anticipated due to swelling using a computer program developed by the author.
