Developing Pavement Performance Prediction Models Using Rutting Criteria for a Cold Region Environment
Maintenance and rehabilitation of roadway pavements in Alaska’s south central and south coast regions are triggered by rutting based on the FHWA threshold of 0.5 in. (12.7 mm) used by Alaska DOT&PF. This leads to short pavement life due to a relatively high rut rate caused by studded tire use during wintertime. Research into the overall rut in these regions shows insignificant rutting from truck traffic. Average pavement resurfacing life in these regions, when considering the effects of rutting, is seven to nine years for freeways and higher for other road classes. This represents about half of the expected design life for principle arterials. Establishing a prediction models that considers the overall rutting will allow agencies to incorporate these models in their pavement management system (PMS). Using rutting and age as the dependent and independent variables, respectively, two models were developed, one for interstate pavements and another for other principal arterial pavements.
