Abstract
In article the reasons of occurrence of vibrating loading of the flexible pavement after movement of cars. It is shown that these vibrating create deformations identical to deformations from action of moving wheels of cars. Absence of the account of this process at designing of the flexible pavement leads them of premature destruction in the conditions of real operation.

Keywords
vibration, layers of the pavement, deformation.
