Abstract

The measurement and prediction of pavement performance condition is an essential component of any pavement management system। In this paper, performance evaluation method for Palestinian roadways was developed. Estimation of the flexible pavement performance life for maintenance and rehabilitation was presented. Data for model development was collected based on the pavement evaluation methods issued by the World Bank for developing countries. The performance model developed in this paper was based on evaluation of various deterministic and probabilistic models using surveyed data for arterials and village access roads in Palestine. The pavement performance models were developed based on calibration of surveyed pavement condition rating index using logistic growth model, and applying regression analysis. The results of the analysis showed that the logistic growth model performed well in fitting the calibrated data for the different roadways considered in this study and the Markov model fitted well for the overlaid arterials. The reconstructed arterial roadway system had longer average performance life than the overlaid arterials. Village access roadway system showed the same behavior. http://www.najah.edu/index.php?page=2149&l=en&extra=%26id%3D311
