Abstract:

The use of granulated materials (especially low-strength materials) in pavements is limited because such materials undergo significant breakage during packing and use. The breakage is mainly due to the extraordinary contact stresses in the particles of the material, which lead to its fragmentation and the formation of melkozem (fine earth) and a sharp decrease in the strength of the material. The method presented here for calculating and controlling the contact stresses in granulated material is the first attempt at the theoretical calculation of stresses in a stochastic medium. Using the model for the stochastic packing of granulated materials proposed by the author as a starting point, the packing density, the number of contacts in an arbitrary cross section through the material, the area of contact between individual particles, and the contact stresses are calculated. The theory presented in this paper makes it possible to carry out various theoretical calculations associated with engineering process control and monitoring of the strength of material over the service life of a road covering, and it can also be used for other problems.
