High-speed rail ballastless track

Page view:

Ballastless track refers to the use of concrete, asphalt mixture and other integral foundation to replace the track structure of loose ballasted ballast bed, and it is the world's advanced track technology. Compared with the ballasted track, the ballastless track avoids the splash ballast, has good smoothness, good stability, long service life, good durability, low maintenance work, and the speed of the train can reach 350 kilometers per hour. Because of the thermal expansion and contraction of concrete, the expansion joints reserved for the construction of ballastless tracks need to be sealed and waterproofed with sealing materials. Baiyue Chemical can provide professional silicone caulking material solutions, which can perfectly solve the problems of aging caulking, insufficient stretching, and poor bonding with the slabs of common caulking materials in domestic ballastless track projects, effectively improving the quality of the rail projects.
