Steel bridges are usually protected from corrosion by paint systems. Since repainting is required several times during the service lives of typical bridges, the maintenance of bridge paint systems has a great influence on the lifecycle cost (LCC) and lifecycle environmental impact. The paint industry has been making efforts to cut down the hazardous materials in the paint, and recently succeeded to develop bridge paints that have much less volatile organic compounds (VOC) than before. The lifecycle analysis (LCA) of steel bridge paint systems in this study considers lifecycle VOC emissions (LCVOC) as well as lifecycle CO2 emissions (LCC02) for rationalized bridges. The LCA of the conventional bridges, I-girder and truss bridges, was also performed and compared with those of the rationalized bridges. The characteristics of LCC, LCVOC and LCC02 of those bridges found from the analyses were discussed in this paper. It was found that there is a trade-off relationship between LCC and LCVOC of the low-VOC paints. In order to solve this trade-off problem, further advances in the paint technology are required.
