Quick-hardening early-strength material applied to emulsified asphalt slurry seal and preparation method of quick-hardening early-strength material
The invention relates to a quick-hardening early-strength material applied to an emulsified asphalt slurry seal and a preparation method of the quick-hardening early-strength material, and belongs to the field of pavement maintenance composite materials. Aiming at the defects in the prior art, the invention provides a slurry seal material capable of rapidly opening traffic, the slurry seal material is prepared from magnesium phosphate cement matrix powder, emulsified asphalt, mixing water, machine-made sand, coarse aggregate and an anti-dispersing agent, and the slurry seal material has the rapid hardening and early strength characteristics of MPC and the flexibility of an emulsified asphalt material. The material can be used only by simple mixing, has the characteristics of high early strength, short setting time and excellent high temperature resistance, is beneficial to shortening the curing time, and improves the high temperature resistance of the cured part.
本发明涉及一种应用于乳化沥青稀浆封层的快硬早强材料及制备方法，属于路面养护复合材料领域。本发明针对现有技术的不足，提供一种能够快速开放交通的稀浆封层材料，由磷酸镁水泥基体粉料、乳化沥青、拌合水、机制砂、粗集料及抗分散剂配制而成，具备MPC的快硬早强特性及乳化沥青材料的柔性。此种材料只需简单拌合便可使用，同时具备早期强度高、凝结时间短、耐高温性能优异的特性，有利于缩短养护时间，同时提升养护处的耐高温性能。
