  • Durability Analysis of Pot Hall Pathcing Mixture in Snowly Cold Region

抄録

On the pavement in snowly cold region, water spray is carried out as a snow removal activity in winter. Therefore in most cases, pavement surface is in water-soaked condition, and it causes the occurrence of a lot of pot halls. Usually, for the pot halls, urgent repair is immediately conducted using patching mixtures. However under these circumstances, the patching mixture falls away soon due to the constraint in the construction. Consequently, as for the maintenance in snowly cold region, it is important to develop the optimal repair method or patching mixture material for such region. In order to provide the basic investigation of this issue, this study statistically evaluates the durability of the patching mixtures of pot halls. Concretely, the occurrence process of pot halls 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 pot halls on the national road in snowly cold region and monitoring data after repairing them.
