摘要:
Elastomeric pads are shown for positioning on top of railroad ties. Pre-cast concrete panels that are commonly provided at railway grade crossings between and alongside the rails rest on the pads. The pads may be extruded from a variety of natural or synthetic elastomeric materials. The pads include a panel or body formed of the elastomeric material with an exterior surface. A synthetic, polymeric coating is applied to at least selected portions of the exterior surface of the elastomeric body. The coating provides improved properties which allow more standard elastomers to be utilized for the main body of the component. The coatings can also be applied to railroad tie boots to provide increased ozone resistance.
