ABSTRACT:
Precast concrete panels are laid end to end on the field sides and between the rails of a track to form a grade crossing. In one embodiment, the panels are screwed to wooden rails upon which they rest. In another embodiment, straps are used to bolt the ends of adjacent panels together to form an integrated unit of large size and mass which is resistant to movement. In making the panel, the top surface of the precast concrete panel is cast against the bottom surface of a mold having an insert therein which forms recesses on the top and end surfaces of each panel into which the strap is received to bolt the panels together.
