This article investigates the effect of Portland cement content and layer thickness (sample) on the modulus of elasticity of crushed stone-sand mixtures. Tests were conducted for Portland cement content of 0%, 5% and 10% by weight and sample thickness of 8 cm, 10 cm, 12 cm. In order to establish an analytical expression for the value of the modulus of elasticity as a function of sample thickness and percentage of mineral binder, the regression analysis method was applied using a similar step-by-step algorithm. Knowledge of the deformation properties of cement-stabilized crushed stone-sand mixtures can help in building substantiated mathematical models of the material for arranging the bases of road pavement, which can be used to model the strength and deformation characteristics of the bases of road pavement. Based on the results obtained, a model of elasticity depending on the thickness was built for each fixed value of the percentage of binder.
