Abstract:
In order to estimate the antifreezing effect and influencing factor of asphalt pavement with salt, this paper determinates the aim value of salinity different effect about melting snow based on the dilute solution law. By determining the conductivity of salt solution, this paper analyses the law of efflorescence along with variety of the salt content under different temperature and void ration. The results show that the antifreezing effect is different by adjusting the salt content of asphalt mixture, the temperature can accelerate the speed of efflorescence. In summer, the main reasons of salt disappearing are high temperature and rain. The speed of efflorescence increases with the raising of void ration. To strictly control the pavement compaction degree is the key for keeping antifreezing effect. 4 tabs, 6 figs, 5 refs.
