A staple in the Prestressed Concrete beam market, the box beam continues to demonstrate its flexibility by providing design options using boxes in an adjacent arrangement with either a cast-in-place concrete deck or an asphalt paved surface or a spread arrangement with stay-in-place forming and a poured concrete deck.

Box beams are fabricated with void material using preformed cellular polystyrene that meets the requirements of ASTM-C578, Type 1.  Void forms are watertight and resistant to breakage and deformation during concrete placement. Because the void is polystyrene, virtually any size or shape can be accommodated to meet project needs.

The AASHTO Type VI modified beam shape was the workhorse for long span prestressed concrete bridges until advancements in concrete material properties lead to the more economic Bulb-T beam shape.  This AASHTO beam section is still specified on some bridge projects and NPP has committed to maintaining the tooling required to continue to fabricate these beams.  Currently the maximum beam length of the AASHTO Type VI (modified) is 165 feet using conventional design.

The PCEF Bulb T beam was developed by the FHWA Prestressed Concrete Committee for Economical Fabrication.  The beam was developed to be a structurally equivalent substitution to the New England Bulb T (NEBT).  NPP fabricates the PCEF beam (as it was developed by the FHWA), the PennDOT modified PA BT, and the NYSDOT modified Deck Bulb T.
