De-icing salts are spread on roads to avoid formation of ice and increase safety on roads during the winter season. De-icing salts, which contain chlorides, initiate and accelerate the corrosion process of reinforcement within the concrete structure. The reinforcement corrosion is the most common reason of reinforced concrete bridge deterioration in Latvia. This paper summarizes the results of several investigations concerning chloride ingress in reinforced concrete bridge structures that are located close to a high intensity roads in Latvia. The amount of chlorides in the concrete cover of different parts of the structures was determined. Road environment has been analyzed and remaining service life predictions for chloride induced reinforcement corrosion have been performed.
