This paper describes effects of surfactant in windshield washer fluid of automobiles on civil structure and environment. Surfactant in windshield washer fluid was spread by tire of automobiles and it easily dissolve asphalt in bituminous pavement under low content, whereas it caused to ion exchange between Ca++ ions in cement concrete and Na+ ions in windshield washer fluid for short time and reached to severe carbonization in cement concrete.Surfactant was also found in air, accompanying with bitumen, diesel exhaust particulate (DEP) and tire.
