Road Frost Calculation of Cement Concrete of Different Combinations

The confirmation of road frost depth is one of the main contents of subgrade antifroze design in seazonal frost areas. In consequence of differences of cement concrete road structure and pavement thickness, difference of road frost depth exists in frost areas. In order to analysis the influence of road frost depth that caused by different pavement materials and pavement structure thicknesses, aim at the typical cement concrete pavement structure, this paper did a reasearch on road frost depth of different pavement materials and pavement structure thicknesses.
