 note = {On the pavement in snowy cold region, water spray is often carried out as snow thawing and removing activities in winter. Therefore in most cases, pavement surface is in wet condition, and it causes the generation of a lot of potholes. Usually, for the potholes, emergency repair is immediately conducted using patching mixtures. However under these circumstances, the patching mixture falls away soon due to the constraint in the repairing work. Consequently, as for the maintenance in snowy cold region, it is important to develop the optimal repair method or patching mixture material for such region. In order to provide the fundamental discussion of this issue, this study statistically evaluates the durability of the patching mixtures of potholes. Concretely, the generation process of potholes are modeled by the Weibull hazard model, and the durability performance of the patching mixtures is verified by estimating the hazard model based on the inspection data of actual potholes on the national road in snowy cold region and monitoring data after repairing them.},
