    Abstract. The modulus of elasticity is one of the main physical and mechanical characteristics of the material, which is used in the calculation of the design of road pavements of auto roads. In our country, the calculation of road pavements for auto roads is carried out in accordance with the requirements of a regulatory document that does not contain data on the modulus of elasticity of soils reinforced with lime and complex binders. At present, in Russia there is no method for determining the elastic modulus of substrates and coatings from soils reinforced with an inorganic binder in laboratory conditions. The absence of these recommendations does not allow to select the mixture with the specified design values of the modulus of elasticity and, accordingly, provide the required values of the modulus of elasticity when constructing road pavements. In laboratory conditions, using the developed method, soil samples common for the territory of the Irkutsk region were taken. Soil compositions are selected and the modulus of elasticity is determined. Portland cement and lime were added as binders. The methodology proposed by the authors will make it possible to obtain materials with specified elastic modulus values and thereby improve the quality of design and construction of road pavements from soils reinforced with inorganic binders.
    Key words: modulus of elasticity of reinforced soil, inorganic binding materials, road pavements, auto roads.
