Temperature Features of CRTSII Slab Ballastless Track in Severe Cold Region
DEStech Transactions on Engineering and Technology Research, 2017 Damages, such as slab end warped, gaps of slab and bed, and cracks of track bed, of CRTSII Slab-Ballastless-Track (SBT) in high speed railway were studied for temperature changing significantly in severe cold regions. First, Contact-Thermal- Resistance (CTR) between Concrete-Asphalt (CA) mortars of the SBT and roadbed were defined.
