To choose the road pavement, it is necessary to determine the traffic intensity and composition of the traffic flow on highways. The existing methods are used depending on the number of axles or carrying capacity of trucks. The purpose of this study is to compare the methods for determining the traffic intensity of vehicles and analyze the values of the minimum total modulus of elasticity. The article presents the results of calculation of the modulus of elasticity based on the traffic flow, the number of axles and carrying capacity of the vehicle. As part of the analysis, tables were compiled, the total estimated number of applications of the design load to a surface point was determined, and the minimum total modulus of elasticity of the road structure was calculated. The result of the research is recommendations for choosing a method for recording traffic intensity depending on the road category and traffic flow composition.
