ABSTRACT:
A technique for rapid installation of corrosion resistant quench car railroad track wherein levelling blocks are embedded in a slag base, a layer of polyethylene is laid over the base and levelling blocks, and a thin layer of gravel is disposed on the polyethylene sheet. Mating precast concrete panels are placed end to end for supporting the ties and rails, with the adjacent edges of the panels overlying the levelling blocks. Ties and rails are installed on the upper surfaces of the panels, and drainage ramp and channel structures are provided on opposite sides of the panels. The panels have vertical holes therein through which an epoxy resin is injected into the underlying gravel layer, the epoxy being horizontally directed by the plastic sheet. The epoxy subsequently hardens, bonding the gravel particles together and forming a stable underlayment for the concrete panels.
