FIELD: control of ice coating, especially on transport facilities. SUBSTANCE: according to first version, method consists in placing the layer above bed with warmth- keeping coat above it; prior to placing this layer, distributing grid is mounted above bed and tubular filters are mounted in bed for reducing specific pressure on soft ground of ice coating field and facilitated discharge of above-frost water to stream bed. In passing water flows in constrained areas, for example through hole in bridge, second version of method is proposed which consists in placing the layer above bed with warmth-keeping layer above it; layer is made in form of triangular box divided into sections by means of vertical shutters made from well filtrating material. EFFECT: enhanced efficiency and reliability of passage of water flows; low cost of method due to use of local materials. 3 cl, 3 dwg
