Water reaction type asphalt cold patch material as well as preparation method and application thereof
The invention provides a water reaction type asphalt cold patch material, a preparation method and application, and the water reaction type asphalt cold patch material comprises the following components in percentage by mass: 97-98% of an asphalt pavement milling material, 0.5-1% of an old asphalt activator and 1.5-2.5% of a cold patch agent, the strength formation of the water reaction type asphalt cold patch material mainly comes from a curing reaction of active components in an old asphalt activator and a cold patch agent under the action of water, so that compared with a traditional asphalt cold patch material, the water reaction type asphalt cold patch material has higher initial strength; and the repaired pavement has better durability after traffic is opened.
本发明提供的一种水反应型沥青冷补料、制备方法及应用，按照质量百分比计，包括以下组分：97～98％的沥青路面铣刨料、0.5～1％的旧沥青活化剂和1.5～2.5％的冷补剂；本发明的水反应型沥青冷补料的强度形成主要来源于旧沥青活化剂和冷补剂中的活性成分在水作用下的固化反应，因此相较于传统沥青冷补料，本发明的水反应型沥青冷补料具有更高的初始强度，修补的路面在开放交通后具备更好的耐久性。
