FIELD: construction.
SUBSTANCE: invention relates to road construction and can be used for stabilization of soils of upper working layer of road and railway roads for various purposes, as well as for installation of strong soil layers of pavement base during construction and repair of roads and railways. Composition for soil stabilization contains, wt. %: screening of rock crushing to 10 mm 68.5–72.5, 0.5–5 mm fraction zeolite with content of clinoptilolite in rock of 40–60 %, 5–15, portland cement 6–8, stabilizing additive of polymer type - product of polyaldol condensation of acetaldehyde with electrolyte additives 1.0–10.0, water is the balance.
EFFECT: technical result is improved strength characteristics of road construction material with lower consumption of binder.
