Nearly 40% of the bridges in the United States are considered deficient and half of the costs needed to repair these bridges is associated with bridge deck deterioration. Chlorides are the primary cause of reinforced concrete deterioration in marine environments and areas of deicing salt usage. The chlorides penetrate the concrete and initiate corrosion of the reinforcing steel. A proven corrosion inhibitor system, the Postrite Post-treatment System, used in reinforced concrete rehabilitation, employs the use of a spray treatment of Postrite (15% calcium nitrite by weight) onto the substrate concrete. The Postrite treatment is followed by a DCI-S (30% calcium nitrite by weight) containing concrete overlay. The structural performance effect of the Postrite post-treatment system used in the resurfaciing of reinforced concrete bridge deck slabs was evaluated in this study. Twelve specimens, two monolithic and ten rehabilitation slabs, were cast. The slabs were tested dynamically for load/deflection analysis. The direct shear and tensile strengths of the overlays were tested and evaluated. Strain gages were used to aid in an overlay to substrate interaction evaluation. The Postrite post-treatment system was determined to have no detrimental effects on the bridge deck slabs performance. The rehabilitation slabs exhibited a smaller deflection than the monolithic under equivalent loadings. The direct shear tests of the overlays exceeded the minimum needed to sustain horizontal shear stresses. The measured direct tensile strengths of the overlays were sufficient to resist delamination which might result from traffic loading or freezing and thawing conditions. The strain gage data indicated that there was partial interaction between the overlay and substrate concretes. / Master of Science
