%X Statement of the problem. The purpose of this study is to obtain data on the level of dynamic im-pact of multi-axle vehicles on the road structure and to establish the dependence of its value on the level of evenness of highway surfacing, a fully loaded mass of vehicles and its rate of speed.Results. Multi-axle vehicle stock and their speed modes were analyzed. Computational models of various types of freight vehicles were developed in the program complex ˇ°Multiple-purpose gearˇ±. A numerical experiment to evaluate a dynamic impact of a traffic flow of multi-axis freight vehi-cles on the road structure was carried out.Conclusions. The values of the dynamic amplification factor of 95 % and factors of reduction for the most common types of freight vehicles in the Russian Federation were defined. The dependences of their values on evenness of a road surfacing, speed rate and a fully loaded mass of a vehicle were established.
