SPECIFICATION OF LOAD PARAMETERS FROM MODERN VEHICLES ON THE PAVEMENT STRUCTURE

Igor Gameliak Vitaliy Raikovskyi Oleksandr Gustieliev

Modern construction standards require the design and construction of roads for loading, compatible with European standards - 11.5 tons per axle, which corresponds to the actual total weight of the vehicle 34 tons with the maximum number of axles (6 axles). Only 25% of state roads meet these normative loads (according to Ukravtodor on Facebook).There are examples when modern heavy goods vehicles (these are heavy construction dump trucks and socalled lorries) significantly exceed the standard load per axle (11.5 tons per axle). This significantly increases the destructive impact and reduces the standard service life of the road. Road traffic regulations in Ukraine prohibit the movement of vehicles with an actual weight of more than 40 tons on roads of national importance. An exception is made for container trucks - the weight limit is 44 tons. On local roads, built mainly for the loading of 6 tons per axle, the movement of vehicles with axle loading over 7 tons or the actual weight of over 24 tons is prohibited. Unfortunately, however, in Ukraine there is a massive violation of these standards. This problem has become even more acute with the change of logistic chains of transportation as a result of the military aggression of Moscow after February 24, 2022. There is no technology or coating in the world capable of withstanding a constant load of 80-120 tons. Even a slight overload (by 1-2 tons) entails the destruction of the road at times. Maximum loaded vehicle, regardless of the number of axles, has a destructive effect on the pavement more than the normative from 2 to 56 times. The paper considers the brands of specific vehicles, most frequently moving on the roads of Ukraine with the specification of the following parameters of loads from the wheels of modern vehicles, namely, the distance between the axles, tire pressure, area and shape of the wheel imprint, depending on the load of the vehicle with subsequent use of the data to calculate the pavement structures

Air pressure in tires, area and shape of wheel imprint, vehicle, axle loading parameters of wheel loads of modern vehicles (distance between axles, air pressure in tires, area and shape of wheel imprint) depending on vehicle loading to calculate their impact on tire design of pavement
