The Key Technologies for Construction Quality Control of Cement Emulsified Asphalt Mortar of CRTS Ballastless Slab Track for High-Speed Railway
CRTSII ballastless slab track used in a high-speed railway was originated from the B(o)gle slab track system of Germany. A cement emulsified asphalt mortar (CEAM) layer, as one of the three core technologies of CRTS ballastless slab track, has been playing a significantly important role in the track structure. Combined with the engineering practice of CEAM layer used in the ballastless slab track for the Beijing-Shanghai high-speed railway and the Shanghai-Hangzhou high-speed railway, the effects of raw materials, mix proportion design and key processes, such as wetting, edge banding, grouting and curing on construction quality were analyzed in this paper. Furthermore, the key technologies of construction quality control were mainly expounded in different construction stages, and the quality control measures were also correspondingly proposed.
