Assessment of Contact Pressure on the Road Pavement Created by Modern Vehicles

July 2, 2021 Engineering 0

When transporting goods by modern means of transportation, the paper investigates the possibility of changing the current limits on vehicle axle loads and total vehicle weight depending on the vehicle type and season. Because of the inefficient use of modern heavy trucks in the transportation of goods, construction companies are forced to violate transportation regulations or obtain special permits. The maximum permissible weight and axle load limits are set for the entire calendar year, which is incorrect because the road structure freezes and becomes a “monolith” in the winter. This implies that the seasonal characteristics of the road structure must be considered when imposing the maximum limits imposed by federal legislation. The pressure generated in the plane of the wheel impression on the road pavement surface is an important factor in the destructive effect on the road pavement, not the vehicle’s load and weight. This paper describes the steps taken during an experiment to assess the contact pressure of modern vehicles on the pavement structure in order to compare the actual data with the normative data. For the permanent road pavement type, experimental data for contact pressure evaluation revealed results that did not exceed the standard value of 0.8 MPa.
