The purpose of the article is to study the dependence of the modulus of deformation of the soil-crushed-stone layer of the road pavement on the content of crushed stone in the soil-crushed-stone mixture and soil moisture in it. This goal was achieved by performing stamp tests of models of road pavements and subgrade. Based on the test results, the modulus of deformation of the subgrade soil and the general modulus of deformation on the surface of the soil-crushed-stone layer were determined, with different content of crushed stone by the volume of the mixture. The smallest value of deformation modulus corresponds to the minimum content of crushed stone in the mixture, which is 40% by volume of the mixture. The greatest value of the modulus of deformation was obtained at the maximum content of crushed stone in the mixture, which is 60% by volume of the mixture. Using the general deformation modulus of different road pavements and deformation modulus of the subgrade soil, the calculation of the deformation modulus of the soil-crushed-stone layer with different crushed stone content in it has been performed. To take into account the influence of the moisture content of the cohesive soil used in the mixture, correction factors are given, the values of which are established by laboratory tests. These coefficients allow calculating the modulus of deformation of the soil-crushed-stone layer depending on the content of crushed stone and the moisture content of the soil used in it.
