The report consists of two volumes. The first volume reviews the WSDOT's specification guidelines for field bending/straightening concrete reinforcing bars, and proposes modifications to those guidelines based on current knowledge. The second volume reviews the WSDOT's specification guidelines for resin grouting epoxy-coated concrete reinforcing bars, and suggests modifications to the guidelines for grouting based on the available information.
The recommendations for bending/straightening reinforcing bars involves bar diameter, bend diameter, heating temperature (hot-bending), and use of non-strain aging steel. The recommendations for resin grouting reinforcing bars involves embedment length hole diameter, and type of resin.
