Evaluation of flexible pavement performance based on HDM-4 and international roughness index

The HDM-4 aids in estimating the deterioration of pavement as well intricate interactions between environment, vehicles, surface, and structure pavement. It predicts how roads will deteriorate over time due to increased traffic. current study was carried out at Hyderabad, particularly which are subjected heavy adopted for Dhulapally Bahadurpally (DB), Gandimaisamma Bowrampet (GB), Medchal (GM), Kompally (KD). Among these commonly observed distress collected like patches, alligator cracking, pothole, rutting, edge drop etc. This papers describes future performance (10 years), progress were predicted using HDM-4. addresses major causes their reasons given section. concluded prediction life 10 years terms IRI values different sections. revealed failure section period with without maintenance, it also helps decision making apply further maintenance treatment this particular routes.
