Abstract
Frost damage of airfield subgrade severely threatens the structure performance and durability of airfield pavement. Based on the frost heaving mechanism of airfield subgrade, mathematical model for coupled moisture and heat was established with elementary equations of moisture and heat. The model was established with finite difference method and one numerical simulation sample was presented. The model and arithmetic were validated by comparison between arithmetical solution and experimental results.
