Patent

CA 2281110

Pre-cast concrete panels are commonly provided at road-rail crossings, to serve as the roadway, but such panels have been liable to premature failure. Rubber caps are placed over the cross-ties, between the panel and the ties, to isolate the panel from the stresses that arise when the panel contacts the ties directly. The caps are ribbed. Two kinds of ribs are provided, some solid and rectangular, others triangular and hollow. The ribbed panels provide resilience and hysteresis over a range of conditions, to prevent fretting and cracking of the panel.
