IS PLAIN WATER WASHING EFFECTIVE ENOUGH? CHLORIDE, SULFATE, AND NITRATE SALTS ON BRIDGES AND THEIR REMOVAL

This article describes research conducted by the Illinois Department of Transportation to measure the amounts of chloride, nitrate, and sulfate concentrations present on 3 pairs of bridges in urban, suburban, and rural environments. One bridge in each pair was washed with water alone, while the other was washed with water and a chemical salt remover. Salt concentrations were measured on each before surface preparation and after pressure washing. The existing coating was in acceptable condition for overcoating; power tool cleaning was specified with blasting only being done at the beam ends under the joints. Washing was a preliminary step before power tool cleaning. The tests were performed over corroded areas before power tool cleaning. Detailed findings are provided and discussed.
