Abstract: 
Presented in the article are results of studies of impacts interrupting layers exercise on the development of reflected cracks. Considered are layers of wet organomineral, fiber-filled and rubber-modified mixes.

The results obtained make it possible to draw conclusion that mixes capable of using most of their internal energy to change their own internal structure are more efficient in hampering development of reflected cracks. Wet organomineral and some rubber-filled mixes are among them.

Another important factor is the relation of plastic and high-elastic deformation values for materials of both the upper pavement layer and the interrupting layer. Incidentally, better resistance to cracking has been demonstrated by structures with better parameters of high-elastic deformations of the upper layer and worse plastic deformation parameters relative to those of the material of interrupting layers. It is interesting to note that absolute magnitudes of these deformations are less important than their relation.
