Railroad Grade Crossing Surfaces – Product Specifications
Product Specifications:
EPA has not identified any national specifications that preclude the use of recovered materials in railroad crossings. Many states, however, have developed guidelines or criteria for use in selecting a crossing surface.
EPA recommends that procuring agencies use the ASTM
standards listed below when purchasing rubber railroad
crossings.
| ASTM Specification Number | Title |
|---|---|
| D 2000-96 | Rubber Products in Automotive Applications |
| D 2240-97 | Rubber Property -- Durometer Hardness |
| D 412-97 | Vulcanized Rubber and Thermoplastic Rubbers and Thermoplastic Elastomers -- Tension |
| D 297-93 | Rubber Products -- Chemical Analysis |
| E 303-93 | Measuring Surface Frictional Properties Using the British Pendulum Tester |
| D 1171-94 | Rubber Deterioration -- Surface Ozone Cracking Outdoors or Chamber (Triangular Specimens) |
| D 573-88 | Deterioration in an Air Oven |
| D 395-89 | Rubber Property -- Compression Set |
| D 257-93 | DC Resistance or Conductance of Insulating Materials |
| D 2137-94 | Rubber Property -- Brittleness Point of Flexible Polymers and Coated Fabrics |
EPA recommends that procuring agencies use the ASTM and AASHTO standards listed below when purchasing concrete railroad grade crossing surfaces.
| Specification Number | Title |
