Working ability of transport networks in large cities is reduced due a damages and deformations of road covering, and also from increasing of amount of vehicles and dynamic influences from them. This study sets that the state of road covering and their operating ability depends on engineering-geological conditions, and can be leveled intensity of the dynamic loads on the example of three presentable areas of streets in Kyiv. The features of engineer-geological and geodynamic conditions which can result in violations of working of roads are selected. A formation of tearing – cracks for areas where lithological composition and physical-mechanical properties of soils is changed as a result of change of the tensely deformed state of the soil bases of roads under act of the dynamic loads are grounded. The obtained results have an important practical value for development and exploitation of a transport network of city, increase of efficiency repairing works.
