FIELD: process engineering.
SUBSTANCE: proposed method consists in making fragments of transformed soil in road soil bed by filling its pores with composite substance by pressure injections made in definite sequence. Horizontal and vertical shields from transformed soil are created around body of road bed subjected to boiling. Note here that horizontal shield is made at depth corresponding to maximum depth of seasonal frosting while, inside said body, fragments are arranged staggered.
EFFECT: efficient elimination of boils.
