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.
