Normal-temperature asphalt mortar taking desulfurized gypsum as filler and mixture
The invention relates to normal-temperature asphalt mortar taking desulfurized gypsum as a filler. The normal-temperature asphalt mortar contains the filler, a curing agent and normal-temperature asphalt, the filler is a mixture of desulfurized gypsum and limestone mineral powder; the desulfurized gypsum is subjected to high-temperature oxidation pretreatment; the mass ratio of the filler to the normal-temperature asphalt is (0.8-1.1): 1; the curing agent is a mixture of Portland cement and metakaolin, and the dosage of the curing agent is 15-25% of that of the normal-temperature asphalt; the normal-temperature asphalt is reaction type normal-temperature liquid asphalt, and is prepared by adding a reaction type liquefying agent and a modifier water-borne epoxy resin emulsion into flowing matrix asphalt and carrying out shear mixing; the reaction type liquefying agent is prepared by taking unsaturated fatty acid as a liquefying agent base material, adding a zwitterionic surfactant and a phenol polymer, and stirring and mixing. On one hand, dependence on limestone can be reduced, on the other hand, reduction treatment and resource reutilization of a large amount of solid waste desulfurized gypsum in a thermal power plant can be achieved, and tests prove that the asphalt mortar has good pavement performance.
本发明涉及一种以脱硫石膏为填料的常温沥青胶浆，其含有填料、固化剂和常温沥青；填料为脱硫石膏和石灰石矿粉的混合物；脱硫石膏经过高温氧化预处理；填料与常温沥青质量比为0.8‑1.1:1；固化剂为硅酸盐水泥与偏高岭土的混合物，其用量为常温沥青的15‑25％；常温沥青为反应型常温液体沥青，是向呈流动态的基质沥青中添加反应型液化剂和改性剂水性环氧树脂乳液并剪切混合制得；反应型液化剂是以不饱和脂肪酸为液化剂基体材料，加入两性离子表面活性剂和苯酚多聚物搅拌混合制得。本发明一方面可减少对石灰岩的依赖，另一方面可对火力发电厂大量固体废弃物脱硫石膏的减量化处理和资源化再利用，且试验证明该沥青胶浆具有良好的路用性能。
