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。
