Grouting material for grouting type composite asphalt pavement
The invention belongs to the field of cement grouting materials, and particularly relates to a grouting material for a grouting type composite asphalt pavement. The grouting material is prepared from, by weight,: 40-80 parts of cement; 5-15 parts of silicon powder; 15 to 32 parts of aeolian sand; 6-20 parts of mineral powder; 0.05-3 parts of a water reducing agent; 0-0.5 part of bentonite; 0.05-0.3 part of cellulose; 2-3 parts of carbon black; 3-6 parts of a rapid hardening agent; 0.3-0.5 part of lithium carbonate; 0.1-0.2 part of an expanding agent; 10-30 parts of polydimethylsiloxane; 2-10 parts of methyl vinyl bis(N-methyl acetamido)silane; and 3-10 parts of N, N-dimethyl formamide. Specifically, when the grouting material is prepared on a construction site, water accounting for 12-18% of the total mass of the raw materials is added; the aeolian sand has the characteristics of small particle size, uniform particle size, looseness, no aggregation and non-plasticity, so that the grouting material has high fluidity; in addition, the polydimethylsiloxane makes up for the non-cohesiveness of the aeolian sand, and the adhesive capacity of the grouting material is effectively improved.
本发明属于水泥灌浆料领域，具体涉及一种灌入式复合沥青路面用灌浆料，所述灌浆料由以下原料按重量比配制而成：水泥40～80份；硅粉5～15份；风积沙15～32份；矿粉6～20份；减水剂0.05～3份；膨润土0～0.5份；纤维素0.05～0.3份；炭黑2～3份；快硬剂3～6份；碳酸锂0.3～0.5份；膨胀剂0.1～0.2份；聚二甲基硅氧烷10～30份；甲基乙烯基双(N‑甲基乙酰氨基)硅烷2～10份；N，N‑二甲基甲酰胺3～10份；具体，在施工现场制备灌浆料时，添加占原料总质量12％～18％的水；上述风积沙具有粒径小、粒径均匀、松散、无聚性以及非塑性的特点，使得灌浆料具有高流动性；另外聚二甲基硅氧烷弥补风积沙的无粘结性，有效提高灌浆料的粘着能力。
