CRTSⅡ型板式无砟轨道水泥乳化沥青砂浆充填层质量控制技术与管理探讨

摘要

Cement emulsified-asphalt mortar(CA mortar),as the main part of CRTS Ⅱ slab track,possesses the performances of complicated recipe,high environment sensibility,rigorous construction technology,and it is the most important and most difficult point of CRTS Ⅱ slab track quality control.Based on the function,performance requirements,construction technology,common quality defects of CA mortar and process management,the key construction technology and quality control measurements of CA mortar of CRTS Ⅱ slab ballastless track are discussed.%水泥乳化沥青砂浆充填层是铁路CRTSⅡ型板式无砟轨道的重要组成部分,具有配方复杂、环境敏感性高、施工工艺要求严格等特点,是无砟轨道施工质量控制的关键和难点。从砂浆充填层的功能作用、性能要求、施工工艺、常见质量缺陷、质量控制技术措施和过程管理等方面,探讨了CRTSⅡ型板式无砟轨道水泥乳化沥青砂浆充填层施工关键技术和质量控制措施等。
