| 摘要 |
Railroad crossing structure for a paved roadway over at least a pair of spaced rails mounted on cross ties to form a railroad track and supported by a ballast comprises a flexible center pad which extends transversely between each pair of spaced rails and flexible side pads which extend transversely between each segment of paved roadway and the rail nearest thereto. The flexible center and side pads are bonded directly to the ballast and comprise a resilient base layer containing a cured flexible thermoset resin and a filler of comminuted scrap rubber, and a resilient wear layer on top of the base layer and containing a cured flexible thermoset resin and a filler of finely divided rubber. |
