ABSTRACT:
A railroad grade crossing structure comprising a plurality of prefabricated, elongated, reinforced concrete panels formed of used, inverted rail sections placed between the rails of each track and outside the rails of each track to provide a smooth durable highway surface; the panels resting on resilient pads supported on elongated crossties containing upstanding studs to fit loosely within sleeves in the bottom of the panels to prevent undue lateral movement; substantially all free space between panels and the rails of each track being filled with a settable elastomeric compound.
