Waterproof crack pouring mortar for pavement cracks
The invention relates to waterproof crack pouring mortar for pavement cracks. The waterproof crack pouring mortar comprises a component A and a component B, wherein the component A is polymer modifiedcationic emulsified asphalt mastic, the component A is polymer modified cationic emulsified asphalt mastic and comprises the following substances in percentage by weight: 80%-95% of cationic emulsified asphalt, 4.5%-18% of a water-based polymer modifier and the balance of rock asphalt powder, the component B comprises the following substances in percentage by weight: 19%-36% of a rapid curing agent, 27%-67% of fine aggregate, 1%-4% of waste rubber particles, 0.2%-0.4% of a fluidizing agent and the balance of water, and the weight ratio of the component A to the component B is 1:(0.5-1.2). Thewaterproof crack pouring mortar provided by the invention has the advantages of appropriate demulsification time, environmental protection, normal temperature construction, simple operation, fast hardening speed and excellent physical and mechanical properties.
本发明涉及一种用于路面裂缝的防水灌缝砂浆，包括A组分和B组分；其中A组分为聚合物改性阳离子乳化沥青胶，A组分为聚合物改性阳离子乳化沥青胶，包括如下重量百分比的物质：80％‑95％阳离子乳化沥青，4.5％‑18％水性聚合物改性剂，余量为岩沥青粉；B组分包括如下重量百分比的物质：19％‑36％快速固化剂、27％‑67％细集料、1‑4％废橡胶粒子、0.2％‑0.4％流化剂和余量的水。A组分与B组分重量比例为1:0.5‑1.2。本发明所述的灌缝砂浆，具有适宜的破乳时间，绿色环保，常温施工，操作简便，硬化速度快，物理力学性能优良。
