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.

Recommended Specifications for Rubber Railroad Grade 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
