FIELD: construction.
SUBSTANCE: invention can be used for amplification of weak natural base, erection of railways roadbed, construction of dams, dams. Method of enhancing natural base formed by weak soils for roadbed erection includes reinforcement of the weak soil massif by mechanical mixing with reinforcing materials, including astringent materials added under pressure. Strengthening is performed at variable depth and width, connected to the calculated mounted zones of maximum attenuation base caused by the worst combination of acting stresses in the base and mechanical properties of weak soil, defining the base (zone of low resistance in the base).
EFFECT: control of depth and width of reinforcement, phasing reinforcement and its performance only part of the massif in zones of maximum attenuation of the base, reduction of material consumption and labour intensity.
