Grouting material for road reinforcement and repair

The invention discloses a grouting material for road reinforcement and repair. The grouting material comprises 60-80 parts of a cementing material, 15-25 parts of an admixture, 2-8 parts of a stabilizer, 0.2-0.8 part of an anionic surfactant and 0.2-1 part of a coagulant, wherein the stabilizer is prepared from 1 to 5.3 parts of sulphoaluminate and 1 to 2.7 parts of talcum powder. After the grouting material is mixed with water, the fluidity can reach 19-22 s, the final setting time is only 4-5 h, the breaking strength of a grouting consolidated body in 3 days and 28 days can reach 5.1-5.9 MPa and 8-8.9 MPa respectively, the compressive strength of the grouting consolidated body in 3 days and 28 days is 22-26 MPa and 53-61 MPa respectively, and the volume expansion rate is 0.02-0.08%. 本发明公开了一种道路加固与修复用注浆材料，包括胶凝材料60-80份、掺合料15-25份、稳定剂2-8份、阴离子型表面活性剂0.2-0.8份及促凝剂0.2-1份；其中，所述稳定剂包括硫铝酸盐1-5.3份及滑石粉1-2.7份。该注浆材料加水拌和后流动度能够达到19-22s，终凝时间仅需4-5h，注浆固结体3天和28天抗折强度分别能够达到5.1-5.9MPa、8-8.9MPa，3天和28天抗压强度分别为22-26MPa、53-61Mpa，体积膨胀率为0.02
