Based on these features, a step-by-step algorithm is proposed, which, starting from a specific configuration of a heavy-haul multi-axle and multi-wheel road train and the road structure, allows for determining the feasibility of a single passage of this vehicle on the highway without its destruction. Among the most significant characteristics of the interaction between heavy-haul multi-wheel vehicles and road structures, the work highlights high axle loads, the mutual overlap of influence radii, and the asymmetry of the stress-strain state in the longitudinal direction. The presence of the aforementioned features is supported by a review of scientific literature. The work also notes the influence of the dynamic impact during the passage of freight vehicles on the performance of the road structure. An algorithm for estimating the design loading parameters for multi-axle vehicles is provided, taking into account the features of the stress-strain state arising in the structure due to the close arrangement of wheels in axle groups relative to each other, and an example of such a calculation for a selected road train is given. To simplify working with the calculation results, a method for compact and clear presentation of the calculated equivalent loads and diameters for each wheel of the vehicle in the form of tables is proposed. Based on the determination of the design loading parameters, the stresses arising in the road structure are determined, and based on their comparison with the ultimate stresses in the layers of the structure, a conclusion is made about the permissibility of a single passage.<\/p>\n<p style=\"text-align: justify;\"><strong>Keywords:<\/strong> multi-axle vehicle; multi-wheel vehicle; heavy-haul vehicle; axle loads; design loading parameters; stress-strain state; road structure; pavement<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mikhail A.
