Abstract:

Chloride ions, which are derived from the salts used for winter highway maintenance, penetrate into the concrete of pavements and bridge decks. This results in corrosion of the rebar and ultimately in damage to the concrete. The subject of this report is a research project in which we attempted to determine the extent to which the presence of humidity, in conjunction with the diurnal cycle, influences the migration of these chloride ions, and whether the application of a rubberized asphalt chip seal.to-the upper concrete surface mitigates or enhances this migration.
