The article presents the results of a study on the design properties of local soils used in the design of flexible highway pavements in the Samarkand region. The physical and mechanical characteristics of clay soils were analyzed depending on their relative moisture content. Based on experimental investigations, regression relationships were established between relative soil moisture and the main strength and deformation parameters, including the angle of internal friction, soil cohesion, and elastic modulus. Statistical analysis confirmed the reliability of the obtained relationships, making them suitable for determining the design parameters of subgrade soils used in pavement engineering. The proposed dependencies improve the accuracy of engineering calculations, enhance the reliability of pavement design solutions, and contribute to increasing the service life of flexible pavements.
