FIELD: process engineering.
SUBSTANCE: proposed method comprises injecting polymer composition, a cryogel, into road bed ground via well. Note here that said polymer composition is injected on both sides of rod bed to make stabilising bearing lattice structure of ground bonded by polymer composition. Proposed polymer composition comprises polyvinyl alcohol, a network-forming agent, boric acid and water. Note here that, additionally, it comprises basalt fiber and/or mineral additives at the following ratio of components in wt %: polyvinyl alcohol 3.0-10, boric acid 0.2-1, basalt fiber and/or mineral additives 0.5-1, and water making the rest.
EFFECT: higher strength of road bed.
