The safety of railway track depends on many factors like proper stations and tunnels good track formations, critical track velocity effects for high-speed lines. Vibration reduction at crossing point motors, track safety at level crossings, voiding at transition zones onto both concrete slab-track and steel/concrete Bridge decks all should meet the stringent standards of railway safety but track technology required to solve these safety critical issues is not well developed to meet the rising demand placed on the railway infrastructure by increasing track usage, axle weight and train speed. The application of polyurethane Railway GeoComposites is now being used to improve railway track safety and performance, typical safety critical areas can be reinforced and stabilized to improve the overall track safety regime and operation.
The track- bed upon which railway sleepers or railroad ties are laid is made from track ballast and it is packed between, below, and around the ties to facilitate drainage of water and to distribute the load from the railroad ties. Good ballast should be strong, hard-wearing, stable, drainable, easy to clean, workable, resistant to deformation, easily available, and reasonably cheap to purchase. It is established that good-quality ballast made of rock is necessary if there is to be a good foundation and adequate Railway drainage.
