Abstract Abstract：Research purposes： Zhengzhou-Xuzhou High-speed Railway is the first test line for expanding application of CRTSⅢ slab track pretensioning prestressed slab in China. The design theory, structure design, construction materials, construction technology and other aspects of CRTS Ⅲ slab track require innovation. There are plenty of problems in interface optimization, slab manufacturing, turnout ballastless track slab, subgrade waterproofing layer optimization, self-compacting concrete preparation and construction, slab layout and fine adjustment that need further study. The research purpose of this paper is to develop and improve the CRTS Ⅲ slab track technology system of high-speed railway. Research conclusions： (1)The complete technology system of CRTSⅢ slab track design, manufacture, and construction has been formed. (2) Since the operation of Zhengzhou-Xuzhou High- speed Railway, ballastless track has been in good condition, and the train has been running smoothly and comfortably. (3) The research results have an important significance in improving our competitiveness in the international market and carrying out the go global strategy.
