Abstract
The rational size distribution of the granular materials is proved in this paper on the basis of the theoretical studies of their optimal structure based on the particle-particle packing probability theory, the laboratory studies in the dependencies of bulk density and static modulus of elasticity of the content of particles of various sizes as well as the calculation of the ultimate crushed rock shearing resistance. The suggestions on the recommended brands according to their frost hardiness, shatter, abrasion and water resistance of the crushed rock used for the open-pit automobile road toppings and bases, based on the analysis of the impact of climatic conditions and loads from the impact of technological vehicles on operational performance of pavement layer, are also given.
