ABSTRACT:
A railroad grade crossing system includes an integral concrete pad that has a pair of spaced-apart cavities located in its upper surface. The cavities have planar bottom surfaces that support rails with their heads flush with the top surface of the pad. The cavities have outer side walls that conform to the shape of the rails. The rails are placed in the cavities against the outer side walls and are secured in place by a rail anchor system. The remainder of the cavities are filled with elastomeric liners that have outer side walls that are shaped to conform to the shape of the rails. The inserts are held in place in the cavities by frictional engagement between bulbous gripping heads, secured to anchors located in the pads, that frictionally interfit into conforming holes located in the inserts.
