ECONOMICAL PRECAST CONCRETE BRIDGES

The research completed under this contract has resulted in the development of five different precast structural superstructure types with details completed which are suitable for inclusion in a set of contract plans. The five types are: (1) Precast Concrete Box Beams, (2) Prestressed Concrete PCI Box Beams, (3) Precast Concrete Double Stem Tee Beams, (4) Precast Concrete Solid Slabs, and (5) Precast Concrete Voided Slabs. Bent and abutment details compatible with the developed superstructure details were also prepared. A trial contract was let in April 1981 with two of the developed types allowed as alternates to a regular type of standard structure. Neither of the alternates was the low bid. It was determined that one of the primary reasons that the alternates were not competitive with the standard structure was that the precast producers were not willing to invest in new forms and associated production hardware which might be used for only one job. It is recommended that same means be found to separate this cost from the contract, thus allowing a true comparison of the new bridge types to be made. (FHWA)
