Testing of a road structure for frost resistance using the curve of frost heaving intensity

The article considers the main provisions of the regulatory methodology for estimation the frost resistance of a road structure. The technique for determining the degree of soil heaving is assessed taking into that the standard for its determination was issued in 1990. The intensity of frost heaving and its curve are being discussed. The characteristic curve of frost heaving intensity is substantiated in relation to road structures. The possibility of its plotting according to laboratory tests is being considered. A new method for testing of a road structure for frost resistance is proposed, the essence of which is illustrated by an example.
