Abstract
In this paper author has made an attempt to develop a Pavement Performance Index (PPI) for a rating of flexible pavements. For the development of the PPI model, normalized method of fuzzy multiple criteria decision making method has been used. Total sixteen parameters have been considered as structural and functional indicators. Expert’s opinion was taken from the field of transportation engineering in the form of linguistic terms. These terms were then converted into fuzzy numbers and a model has been developed to determine pavement performance index. The evaluation of the model has been shown in the paper by illustrative example, in which three segments of roads were considered and the values for all indicators were assumed. By converting these values into fuzzy number PPI of the three segments of the road was evaluated and rating of roads was done. From this research work, it has been concluded that this method can be used for the evaluation of pavement performance and their rating.
