Abstract
A concrete railroad grade crossing comprised of a precast concrete gauge panel extending between the rails and precast concrete approach panels which extend between each rail and the roadway. Elastomeric gauge seals are provided on the opposite sides of the gauge panels for sealing the space between the sides of the gauge panels and the rails. Elastomeric approach seals are provided on the inner ends of the approach panels for engagement with the outer sides of the rails. The inner ends of the seals are at least partially embedded in the associated panels and are additionally held in place by angle members embedded in the panels which are received in slots formed in the seals.
