摘要
介绍了高速铁路CRTII型板用乳化沥青和砂浆的制备方法和工艺,选取了合适的基质沥青原料,通过乳化沥青和干粉料的拌和效果和工作性能为评价准则,找到了性能可靠的乳化沥青配方体系。制备的乳化沥青与干粉料相容性较好,所配制的水泥乳化沥青砂浆的各项性能指标完全符合我国高速铁路CRTSII型板式无砟轨道水泥乳化沥青砂浆垫层的施工要求,并在多条高铁线路上得到了应用。
This paper introduced preparation method and process of emulsified asphalt and mortar used in the high - speed railway CRTSⅡ type plate. Through the mixing effect of emulsified asphalt and dry powder based on the work of selecting a kind of suitable matrix asphalt, a reliable asphalt emulsion compounding system was found. It had good compatibility between emulsified asphalt and dry powder. The performance of prepared emulsified asphalt cement mortar fully met the construction requirements of high - speed railway CRTSⅡtype track of China, and it was applied in several high - speed railway lines.
