State of the Art in the Utilization of Deck Bridges with Encased Filler-Beams in the Standard Construction Practice

Abstract

Deck bridges with encased filler-beams have been used in construction for a long time. Nowadays they are employed mainly in the refurbishment of railways and in road construction. Regarding the method of construction, they can be divided into monolithic/cast-in-place (constructed fully in its final location) or prefabricated/precast structures (built at another location and then transported to their final location for placement in the full structure). Both methods of construction have certain advantages and disadvantages. Decision-making and selecting a better alternative depends on the building conditions and a means of transport (whether a road or railway) running on the bridge.
