Abstract: The present disclosure is directed to a precast collar for providing a protective structure (ex.—a surround structure), a proprietary support structure and an appearance-enhancing (ex.—non-distracting) base accessory for a pole foundation and a pole (ex.—for a utility pole foundation and utility pole). The precast collar may be formed of precast concrete and may be of sufficient dimensions and construction for at least substantially surrounding and for protecting a support structure and body structure portion of a pole foundation. The precast collar may form a recessed portion for receiving a support structure of a pole foundation. The precast collar may be supported upon the pole foundation via the support structure of the pole foundation, while providing access to a base structure of the pole foundation via a cavity formed through the collar, so that said base structure may be connected to a pole.

Abstract: A concrete railroad grade crossing comprised of a precast concrete gauge panel extending between the rails and precast concrete field 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 field seals are provided on the inner ends of the field panels for engagement with the outer sides of the rails. The seals are secured to the panels by bolt and channel member assemblies.
