For urban road there is no definite performance indicating procedure. There is a procedure to find out pavement condition index. This procedure is depending on two factor namely severity and extent. We are evaluating the pavement performance by considering seven parameters which are causes to pavement deterioration. To find out the pavement performance index weightage of each deteriorating factor is required. To give the weightage to each deteriorating parameter on the basis of severity we use analytical hierarchy process (AHP). Before giving input to AHP we first normalize the data by simple mathematical equation. Rating guidelines developed on the basis of research paper and data collection for both severity and extent. Each distress having rating from 0-5 where 0 is bad performance and 5 is very good performance of road stretch. AHP gives the consistency ratio; if this consistency index fails to reach a required level then answers to comparisons may be re-examined. In this study the consistency ratio is less than10%. We have done survey on 1.8km stretch from Sunday market jaitala to Mokhare College. We found out all deteriorating parameter rating by finding their values. The pavement performance index is found out by adding and multiplying each pavement deteriorating parameters rating with their respective weightages.
