Investigation of the Effect of the "MADOR" Modifier on the Strength and Water Resistance of Cement-Reinforced Discrete Mineral Materials for Road Construction

Statement of the problem. In the territory of the Russian Federation, a large number of cement modifiers are used to strengthen and stabilize soils during the construction and repair of highways. At the same time, the determination of the scope of modifying additives and their effectiveness requires a large number of laboratory studies, both according to GOST-normalized indicators and alternative methods, taking into account foreign experience. This circumstance led to the need to conduct a study of one of the additives to cement used to strengthen soils in road construction. Results. The review of the results of studies of the effectiveness of the use of the modifier "MADOR" for non-cohesive mineral materials reinforced with cement for the construction of structural layers of pavement is given. The results of studies of strength characteristics, water resistance and water absorption of materials reinforced with cement together with the modifier "MADOR" are presented. Conclusions. A significant positive effect has been established from the use of the "MADOR" modifier to strengthen the studied materials and soils in combination with cement. It is proposed to use the studied materials reinforced with the "MADOR" modifier together with cement in the structural layers of the road surface of highways.
