    摘要: The present invention relates to a polyurethane ballast layer, the method for preparing the same and a railway comprising the polyurethane ballast layer. The polyurethane ballast layer provided in this invention comprises a polyurethane-filled ballast layer and a polyurethane external protective layer, wherein the polyurethane-filled ballast layer comprises ballasts and polyurethane foam filled in the space among the ballasts. The polyurethane ballast layer provided in this invention can reduce the probability of ballast crashing, shifting and cracking under heavy load, and separate the ballast track from the outside environment to prevent rain, snow and wastes from entering into the internal space of the ballast track bed. Furthermore, the polyurethane ballast layer can keep the polyurethane foam filled in the ballasts layer away from water in the outside environment to avoid hydrolysis. The polyurethane ballast layer presented in this invention can be used in the railway ballast track bed to extend the track bed maintenance cycle, and save maintenance cost significantly.
