ABSTRACT
Mechanical and natural-climatic factors influence over the strength and longevity of the road constructions. One of the defining natural-climatic factors is temperature. Physic-mechanic and other indices of the asphalt-concrete change within the limits depending on the temperature. The temperature regime defines also the process of the freezing and melting of the subgrade and the layers of the pavement. Therefore, the complex (experimental and theoretical) research of the temperature regime of the flexible pavement and its subgrade in the non-stationary carrying-out has been considered in this paper.
