Bridge Deck Wearing Surfaces
Several commercially available bridge deck overlay systems claim to be waterproof and reduce deterioration caused by chloride laden water from penetrating concrete bridge decks. An attempt was made to quantify the in-service waterproofing qualities of several overlay systems by monitoring the moisture content of aged concrete using the relative humidity level in a closed hole in an existing concrete bridge deck. Unfortunately, the creation of a closed cavity in the concrete appears to attract internal moisture and creates a near 100% relative humidity condition. The research concludes that using commercially available relative humidity sensors is not a viable method of evaluating moisture movement in concrete bridge decks.
