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.
