Abstract:Research purposes:The HGT made from a concrete mixed material with low elastic property has been used for the ballast base of bi-block ballastless roadbed in the integrated experimental sections of Suining-Chongqing Passenger Dedicated Line and the Wuhan-Guangzhou Passenger Dedicated Line. The material is a new developed material and first applied in China, and the paving construction technology for it is a new technique in China. This paper researches on the material for HGT and construction technology of slip-form paving for it.
Research conclusions:The applications of the HGT and its slip-form paving in the Suining-Chongqing Passenger Dedicated Line and the Wuhan-Guangzhou Passenger Dedicated Line show the HGT made from a concrete mixed material with low elastic property can meet the technical requirements and is suitable for slip-form paving to achieve the expected goal. For example, there was no problem appeared to HGT in the MU test at the speed of 351km/h carried out on Wuhan-Guangzhou Passenger Dedicated Line, and it shows the HGT and paving technology are successful.
