**6. Principle of consequential change of deformation types**

As it is known, the self-organization phenomenon occurs in complicated open thermodynamics systems and new structures occur in them in critical conditions such as Benar's cells, separated cells of living organisms, laser ray, and so on. Occurrence of specific dissipative structures in critical low-temperature conditions on the asphalt concrete pavement has been shown in the works [15–17, 47]. The provided above staging of the fatigue failure for the asphalt concrete pavement, possibility in principle for occurrence of dissipative structures in it at critical conditions as a result of self-organization of its structural elements, significant dependence of single loading, cyclic and long-term strength of the asphalt concrete on deformation type (stressed condition) and existence of residual strength at another deformation type after failure allow formulating of a new regularity for the fatigue failure:

*Fatigue failure of an asphalt concrete pavement under repeated load impact is realized according to the consequently changing stages in every of which pavement parts function as specific dissipative structures with characteristic deformation type, which interchange in the sequence of: tension-bending-compression.*
