| Abstract: | Basing on analyzing the characteristics of pavement frost environment, utilizing the annual hourly temperatures within pavement concrete calculated by finite difference method, the natural freeze-thaw cycle of pavement concrete and its parameters are defined and quantitatively analyzed. So an equation, which calculates the annual times of pavement concrete natural freeze-thaw cycle was developed and the cycle parameters, including temperature decreasing speed of freezing, length of freezing time and lowest freezing temperature were statistically calculated. |
