In cold regions, such as Alaska, using studded tires is common among the public when driving in icy and snowy conditions. However, studded tires cause extensive wear to asphalt pavement, reducing pavement life. This study utilized wear rate models and proposed a methodology to quantify the pavement damage as a result of studded tires. The approach is applied in a case study from a sample of Alaska statewide road segments. Parking lot surveys and household surveys were employed to examine the

A pavement life cycle cost review was established considering a number of variables to discover a realistic cost of roadway resurfacing and rehabilitation. Wear rates due to studded tires and rut rates due to wheel loads were found for different highway classes. Results show higher average wear rates due to studded passenger vehicles on freeways (0.0116 in. per 100,000 studded vehicles) than the average rut rates due to heavy wheel loads (0.0049 in. per 100,000 trucks) and lower average wear rates on arterial and collector roads (0.0062 in. and 0.0045 in. per 100,000 studded vehicles, respectively). Finally, estimates showed that studded tire use reduced asphalt surface life on the selected freeway sample in the case study by about 7 years, which is about 47% loss in pavement life based on the initial design life of 15 years.
