To avoid formation of ice on roads de-icing salts are spread during the winter season. The corrosion of the reinforcement in concrete by de-icing salts is one of the major issues concerning the durability of reinforced concrete structures. Reinforced concrete bridge piers have been investigated with the purpose to determine the service life and the amount of damage created by using de-icing salts on roads. The bridge piers have been investigated for chloride ingress during the autumn of 2007. Seven chloride ingress profiles have been obtained and analyzed. The results show that the exposure to chlorides is generally highest for surfaces facing towards the traffic. It has been noted that the position and shape of the bridge piers is of great importance. The surfaces facing towards traffic are in danger to have reinforcement corrosion in coming years. Results for other surfaces show that there won’t be a reinforcement corrosion initated by de-icing salts for current road environment for the remaining service life.
