In-house Fabrication of Precast Concrete Bridge Slabs

Report No: 77-R33

Published in 1976

About the report:

Information is reported on the labor, equipment, material, and cost required for seven bridge maintenance situations in which state forces widened or replaced an existing short span structure. Precast concrete slabs were installed at three of the locations, concrete slabs were cast at the site at two of the locations, and steel stringer-timber deck superstructures were constructed at the other two locations. Data indicate that precast concrete slabs used in the 10'-35' span range provide for considerably more efficiency and economy than may be obtained with conventional alternative superstructures of timber on steel stringers and site-cast concrete. The use of precast slabs provides for a 25% or more reduction in total cost, an 80% reduction in on-site construction time; and a 65% reduction in the fuel required for travel to and from the bridge site. Since precast slabs can be placed in one work day, a closed road and a traffic detour may be eliminated.
