Environment-friendly high-dosage RAP regenerated cement stabilized macadam mixture and preparation method thereof
The invention belongs to the technical field of cement stabilized macadam mixture preparation, and particularly relates to an environment-friendly high-mixing-amount RAP recycled cement stabilized macadam mixture and a preparation method thereof, and the high-mixing-amount RAP water-stable mixture comprises graded broken stone, cement and a curing-free agent; the graded broken stone is prepared from the following materials in percentage by mass: 12 to 20 percent of RAP1 # material, 18 to 20 percent of RAP2 # material, 10 percent of RAP3 # material, 32 to 42 percent of coarse aggregate and 18 percent of fine aggregate; the addition amount of the cement accounts for 2.5%-4% of the total weight of the high-doping-amount RAP regenerated water-stable mixture; the addition amount of the curing-free agent is 6-8% of the mass of the cement. And various parameters of the recycled RAP material are limited through a joint stirring method, so that the use range of the RAP material can be standardized, and the mechanical property of the high-dosage RAP water-stable mixture is improved.
本发明属于水泥稳定碎石混合料制备技术领域，具体涉及一种环保型高掺量RAP再生水泥稳定碎石混合料及其制备方法，其中高掺量RAP水稳混合料包括级配碎石、水泥和免养生剂；级配碎石按质量百分比计由以下物料组成：12%～20%RAP1#料、18%～20%RAP2#料、10%RAP3#料、32%～42%粗集料、18%细集料；水泥添加量占高掺量RAP再生水稳混合料总重量的2.5%～4%；免养生剂添加量为水泥质量的6%～8%。通过共同搅拌法，限定回收RAP料的各种参数，能够规范RAP料使用范围，提高了高掺量RAP水稳混合料力学性能。
