ABSTRACT

The transit of superheavy vehicles on the road network requires a specific authorisation, which results from a critical analysis of the vehicle's effect on the pavement and other road infrastructure. The assessment of the damage caused by these atypical loading conditions is based on the mechanistic-empirical approach to pavement analysis. In practice, two critical behaviours are taken as reference: (1) fatigue failure and (2) structural rutting of the pavement. However, damage assessment is carried out based on partial stresses, making it an incomplete approach to the conditions described by superheavy loads. This article compares different analysis criteria to quantify the damage caused by superheavy trucks and identifies common interest elements. Additionally, a novel approach is used to study the partial contribution of pavement layers to the structure's performance under atypical loading conditions.

摘要

超重型车辆在道路网络上的运输需要特定的授权，这是对车辆对人行道和其他道路基础设施的影响进行严格分析的结果。对这些非典型载荷条件造成的损坏的评估是基于路面分析的机械经验方法。在实践中，两个关键行为被作为参考：（1）疲劳破坏和（2）路面的结构车辙。然而，损伤评估是基于局部应力进行的，这使得它无法完全解决超重载荷所描述的条件。本文比较了不同的分析标准，以量化超重型卡车造成的损害，并确定了共同的利益要素。此外，
