ASPHALT PAVING MATERIAL PACKING BODY AND ASPHALT PAVING REPAIR METHOD
To provide an asphalt paving material packing body and an asphalt paving repair method capable of repairing asphalt imparted with enhanced strength and durability, due to strength development of a hydraulic asphalt mixture enabled by steps of installing a hydraulic asphalt mixture bagged in a highly water soluble packing member at a repair object location, and then, applying water to cause the packing member to dissolve and disappear so that no impurities, such as the packing member remains in the asphalt paving after the repair.SOLUTION: Provided are a packing member 10 made of a water soluble polyvinyl alcohol resin; and a hydraulic asphalt mixture 20 contained in the packing member 10 and containing aggregate, asphalt, and a lubricating solidifying material.SELECTED DRAWING: Figure 1
【課題】水溶性の高い梱包体に袋詰した水硬性アスファルト混合物を補修対象箇所に設置した後に、水が付与されることで、包装部材が溶解消失し、水硬性アスファルト混合物が強度発現することにより、補修後にアスファルト舗装内に包装部材等の不純物が残存せずに、強度及び耐久性が高いアスファルト補修が可能なアスファルト舗装材梱包体及びアスファルト舗装補修方法を提供する。【解決手段】水溶性を有するポリビニルアルコール樹脂製の包装部材１０と、包装部材１０に内包され、骨材、アスファルト及び潤滑性固化材を含有する水硬性アスファルト混合物２０とを備える。【選択図】図１
