• Abstract:
  In 1991, two Durafiber polypropylene fiber reinforced concrete lined detention ponds were constructed. The detention ponds are located on the north side of the 181st Avenue Interchange, on the Columbia River Highway (I-84), approximately ten miles east of Portland, Oregon.
  
  The original design called for the detention ponds to be constructed with six-inch welded wire fabric reinforced concrete over an impermeable geomembrane. An alternate to this design, replacing the welded-wire fabric reinforced concrete with polypropylene fiber reinforced concrete, was proposed by the contractor through a no cost price agreement and approved by the Oregon Department of Transportation (ODOT) and Federal Highway Administration (FHWA). The replacement of welded-wire fabric reinforced concrete with polypropylene fiber reinforced concrete created no problems with respect to mixing, placing, workability, finishability, or visual appearance. The use of fiber reinforced concrete on this project resulted in a small cost reduction relative to the use of welded wire fabric reinforced concrete. However, as a result of the field observations made during the final site visit, it was concluded that the reinforcing fibers appeared to have provided no added value toward strengthening the ponds shotcreted layers; although, the ponds are performing satisfactorily.
  
  ODOT Research Unit Staff should do the following: 1. If funds are available, the fiber reinforced concrete should continue to be monitored until it fails. 2. If polypropylene fiber reinforced concrete is used on another ODOT projct, it should be evaluated.
