FIELD: road construction.
SUBSTANCE: invention relates to road construction and can be used to create functional layers of the roadbed by comprehensively strengthening local soils during the construction of roads and railways. The composition for the creation of functional layers of the roadbed contains, by wt. %: sand 82-85; complex binder 8-10; water the rest. The complex binder was obtained by joint grinding of Portland cement clinker, gypsum, anionic oligomer: the Melment F10 additive, wollastonite, active silica with a specific surface area of 450 m2/kg at their mass ratio of 17:1:0.2:1.7:0.1, respectively.
EFFECT: increase in the physical and mechanical characteristics of the composition for the arrangement of functional layers of the roadbed.
