凍結に伴うNaCl湿潤アスファルト舗装のすべり抵抗低下 Decrease in Sliding Resistance of Wet Asphalt Pavement with Sodium Chloride due to Freezing
Freezing experiment of sodium chloride (NaCl) solution on an asphalt pavement was carried out and the mass ice content, i, and the concentration NaCl, C s, were measured at different elapsed time of the experiment.A forecast model of snow/ice condition on a road developed by authors could reproduce the increase in i and C s due to freezing. Our model, furthermore, could reproduce the decrease in the resistance (BPN) of the asphalt pavement covered with NaCl solution due to freezing using the BPN- i relation obtained from our another experiment.
