Abstract: In a system that extends a paved roadway across a pair of parallel, spaced apart rails using a gauge panel between the pair of rails and a pair of field panels between each rail and the roadway, edge protectors of the present invention are used to protect the edges of the panels. A seal is positioned between each rail and a longitudinal rail edge. In one embodiment, a longitudinal rail edge protector has a surface leg that is substantially even with the top surface of the panel and a securing leg that secures the seal to the panel either by being embedded in the seal or by covering or overlapping the seal. In an alternate embodiment, a longitudinal rail edge protector has a surface leg, a securing leg, and a securing extension that is embedded into the seal to secure the seal to the panel. In another alternate embodiment, the securing edge protector is flat and is embedded into the seal to secure the seal to the panel. Anchors may be used to attach the longitudinal rail edge protector to the panel.

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.

Abstract: A rail grade crossing includes precast concrete panels which extend substantially between the roadway and the rails and between the rails. Elastomeric seals that are cast into the panels when they are formed fit between the panels and the rails. Because the seals are cast into the panels, the panels and seals are an integral unit which facilitates installation and removal of the panels.

Abstract: The present invention relates to a pad which supports a utility access conduit in a roadway and permits relative movement between the conduit and the roadway without damaging the seal between them and which supports vehicular traffic for a time comparable to the life of the roadway itself, without the occurrence of any dipping in the vicinity of the access conduit. This is accomplished with a rectangular block or rubber or similar compressibly resilient elastomeric material which has an opening passing through it that snugly engages the access conduit. The invention also relates to a method for installing the pad in either a new or existing roadway.

Abstract: The railroad crossing tie-down system of the present invention includes anchor plates which are attached permanently to railroad ties with the side margins of the anchor plates projecting outwardly from the sides of the ties. The crossing elements which will be attached by the system have openings passing through them at selected locations midway between adjacent ties. Cross tie beams having nuts located at their centers have a length which is slightly greater than the distance between adjacent ties. Elongate bolts which extend through the openings in the crossing elements have threaded extremeties which will engage the nuts. Before the crossing elements are installed on the anchor plates the bolts are inserted through the openings and the cross tie beams are attached to them and are oriented so that the cross tie beams are parallel with the ties.
