Prefabricated Bridge Elements and Systems for Bridge Construction

Precast and Prestress Slab Spans for Bridge Construction Precast slab members can be constructed in various widths, depth, and length to built spans up to 15 m. shorter spans might be normally reinforced and cast in simple precast plants whereas long spans are commonly voided and post tensioned or prestressed.

CRACK CONTROL IN TOPPINGS FOR PRECAST FLAT SLAB BRIDGE DECK ...

Precast flat slab bridges are a practical alternative to traditional deck/girder designs used for short span bridges. Using precast slabs reduces the price of bridge construction by virtually eliminating the need for formwork thus making it economically attractive. It allows for faster construction time and quicker project turnover. According ...

Full-Depth Precast Concrete Bridge Deck Panel Systems

Since 1974, significant advances have been made in the construction of bridge decks built with full-depth precast concrete deck panels. The following sections provide infor- mation on the connection details and grout material used in these bridges.

Precast Bridge Decks - PCI

The information is applicable for new bridge deck construction or bridge deck replacement. The first part is intended to provide an introduction to the relatively new technology of full-depth precast bridge deck panel system. It describes the system and shows the advantages of this system over the traditional CIP bridge deck.

INNOVATIVE PRECAST CONCRETE DECK SLABS - tac-atc.ca

The deck replacement construction schedule will be controlled by the demolition, regardless of the type of replacement deck system. The deck replacement system should have dead load similar to the original design deck loading (6 ? inches or 165mm thick deck slabs plus 50mm overlay). The stringers, floor trusses, cables, hangers, etc.

Hollowcore Slabs | Taracon Precast | Produced In-House

Along with being significantly easier to lift and handle during the construction process, hollowcore slabs lower construction costs related to the amount of material required to cast the slabs as well as the cost to transport the finished product to the job site.

Floor systems - Steelconstruction.info

The floor slab may be in the form of a precast concrete slab or a composite slab with metal decking (either shallow or deep decking may be used). An added benefit is that some forms of shallow floor construction inherently achieve composite interaction between the beams and slab, thereby enhancing structural efficiency.
