FIELD TESTS OF RESISTANCE TO CHLORIDE ION PENETRATION ON SEALED CONCRETE PAVEMENT
The results and methodologies of a field study of portland cement concrete sealers on a traffic bearing surface in Indiana are presented. The study was to examine the resistance of chloride ion penetration on sealed concrete pavement. Various generic sealers were put on the surface of concrete pavement, then replicate samples were taken from the unsealed and sealed parts of the pavement. The content of chloride ions in the samples was analyzed and compared with the results of NCHRP Report 244. After 3 years of exposure, the test areas for some generic sealers continued to demonstrate better effectiveness than others in maintaining resistance to chloride ion penetration in concrete. Meanwhile, the field test results are significantly different from the laboratory test results in this study.
