FIELD: construction.
SUBSTANCE: invention is related to method for local reinforcement of foundation bed under coupling unit of precast surfacing on motor roads made of reinforced concrete slabs, which experience high stresses from action of heavy vehicle wheels.
EFFECT: in local reinforcement under coupling unit of sand foundation by impregnating binder (for instance, liquid cement-polymer one) until strong structure of finely ground concrete is achieved with compression strength of at least rc=8,0 MPa.
