Abstract

 It is necessary for efficient maintenance to predict behavior of deterioration factors by simulation instead of observation. In this paper, the change of salt environment due to anti-freezing salt scattered by vehicle running was predicted. When a rectangular-modeled vehicle runs at 50 km/h or 80 km/h in windlessness, anti-freezing salt was scattered toward the side direction in the range of 1.5 times as long as the vehicle width, and toward the vertical direction in the range of the same as the vehicle height. When a vehicle runs at 50 km/h in the cross wind whose speed is 10 m/s at 10 m height, anti-freezing salt was carried to more than 5.5 times as long as the vehicle width on the leeward of the cross wind, and scattered toward the vertical direction in the range of more than 2 times as long as the vehicle height. From this paper, the necessity is confirmed to pay attention to structural design and maintenance considering the salinity supply due to anti-freezing salt scattered by vehicle running.
