This paper presents the results of determining the actual strength and deformability of large-block soils in laboratory conditions on model mixtures. The strength deformative properties of large-block soils were determined on a large-sized device, the minimum size of which should be five times larger than the maximum size of the fraction. The main factors influencing the results of the experiments include: soil characteristics, loading characteristics and device characteristics. At the same time, the large-scale effect associated with the decompression of the end and side surfaces of the soil samples, as well as the friction of the samples on the side surfaces of the device, resulted in more accurate determination of the actual properties of large-block soils.
