"Moisture-curing type of highly durable cold asphalt repair material" possess the durability as much as the hot asphalt mixture, though they're bagged cold asphalt repair material. Therefore, it's suitable for repairs in a pothole and is used quite much. However, the damage which are a crack and aggregate scatter, etc. when it's repaired at the part several square meters of wide range and a twisting action of a tire frequently generate, it forms, there is a problem. To overcome these challenges, the authors developed for improvement of a flexibility of this cold asphalt repairing materials and resistance to using degradation. This article reports on a results of indoor evaluation test and a paving test.
