Flexural Performance of Ultra-High Performance Concrete Ballastless Track Slabs
2016 Joint Rail Conference, 2016 Ballastless track slab offers excellent stability and durability and has been well accepted in high-speed railways worldwide. Rails are typically laid on precast concrete slabs that are subjected to dynamic load transferred from the rails. Cracks can be induced by shrinkage and mechanical loading in concrete, which accelerates the degradation and ...
