This report summarizes interim reports concerning grout and grouting procedures, and bridge deck cathodic protection. Variations in grout materials, composition, and mixing technique were evaluated by means of standard tests. In some cases, statistical analyses were performed and mathematical relationships were developed. The physical property of viscosity, as determined by the flow cone, was found to be the most practical indicator for evaluating grout quality. A cathodic protection system was developed, designed, and installed on a bridge that was scheduled for the repair of corrosion-caused deck distress. Data indicate that the application of nominal amounts of current and voltage arrested corrosion of the top mat of reinforcing steel in 3300 sq ft of bridge deck. Experimental rebonding of delaminated areas by epoxy injection was partially successful. /FHWA/
