FIELD: ice engineering.
SUBSTANCE: ice crossing roadway and ice surface adjacent on both sides are covered with heat-insulating material with possibility of its removal to width of 10-15 m from the crossing axis.
EFFECT: prolonged period of operation of ice crossing under conditions of weakening of carrying capacity of ice under effect of positive air temperature in spring.
