摘要

现代建筑标准要求设计和施工的道路装载,兼容欧洲标准- 11.5吨每轴,这对应于车辆的实际总重量34吨与最大轴数(6轴)。只有25%的国道符合这些标准载荷(根据Facebook上的Ukravtodor)[1-6]。现代重型货车(这些是重型建筑自卸车和所谓的卡车)明显超过每轴标准载荷(每轴11.5吨)的例子。这大大增加了破坏性影响,降低了道路的标准使用寿命。乌克兰的道路交通条例禁止实际重量超过40吨的车辆在国家重要道路上行驶。集装箱卡车是个例外——重量限制为44吨。在当地以每轴载重6吨为主的道路上,禁止轴重超过7吨或者实际重量超过24吨的车辆通行。然而,不幸的是,乌克兰严重违反了这些标准。随着2022年2月24日莫斯科的军事侵略导致运输物流链的变化,这个问题变得更加严重。世界上没有一种技术或涂层能够承受80-120吨的恒定载荷。即使是轻微的超载(1-2吨),有时也会导致道路的破坏。无论车轴数如何,最大载重车辆对路面的破坏作用是标准车辆的2 ~ 56倍。本文考虑了特定车辆的品牌,最频繁地移动在乌克兰的道路上与现代车辆的车轮载荷的以下参数的规格,即,轴之间的距离,轮胎压力,面积和形状的车轮印记,这取决于车辆的载荷与随后使用的数据来计算路面结构。

SPECIFICATION OF LOAD PARAMETERS FROM MODERN VEHICLES ON THE PAVEMENT STRUCTURE
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) [1-6] .There are examples when modern heavy goods vehicles (these are heavy construction dump trucks and so-called 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.
