Abstract:

A field implementation trial using the grooved-deep-impregnation technique with calcium nitrite as the impregnate was conducted under Strategic Highway Research Program (SHRP) Contract C-103 in July, 1990. This paper presents the results of the corrosion assessment surveys prior to treatment and at various time intervals over a 9 year period. Corrosion assessment surveys included concrete cover depth, chloride content, corrosion potentials and rates and calcium nitrite content. The results of the corrosion surveys support the conclusion that the deep impregnation with calcium nitrite arrested active corrosion cells and has protected the bridge deck section from continued corrosion damage over the 9 year assessment period.
