ABSTRACT:
This invention relates to concrete railroad crossings and a process of constructing such railroad crossings which are essentially isolated from all moving parts of the rail system through the employment of compressible foam material to separate the surface of the rails, ties, and other track handware normally in direct contact with a concrete crossing. The crossing is supported on the sub-grade between the rail ties.
