Pavement evaluation in cold regions is focused on the distress to pavements during the thaw-weakening period. To minimize the damage to the pavement structure, state DOTs apply load restrictions for a certain period of time. The length of the load restriction period has a significant impact on the logging and trucking industries. Over the years, state and federal agencies have developed empirical and semi-mechanistic approaches for predicting the onset of the critical period during thaw, load restriction durations, and the allowable loads on pavements. This paper reviews the current state of the art in pavement evaluation in cold regions.
