Abstract:Besed on the mathematic model of temperature field suggested by V. S. Rugiyanov (1959), we successfully add a correction term of transfer heat considered the fact that moisture migrates in soil. Using the finite differential method we calculate the temperature field and frozen depth of pavement proper when the road is freezing by degrees with moisture migration. We get a theoretical explaination of some phenomena which appear in the testedroad rather than traditional conception, and then provide a basis for selecting materials of road foundation against frozen damage.
Keywords:temperature field   correction term of transfer heat   frozen depth   moisture migration
