Abstract

AbstractSuperload vehicles (SLs) are typically defined as vehicles having a gross vehicle weight (GVW) greater than 890 kN. SLs often consist of unique axle configurations that may cause significant damage to pavements. Research has been mainly limited to SLs on asphalt pavements, therefore the effect of SLs on concrete pavements is not well established. In this study, fatigue stresses in concrete pavements were quantified for a database of pavement structures and SLs to identify critical conditions that contribute to fatigue damage. A series of load pulses were constructed from a database of finite element results to identify conditions and locations within the slab for peak stress development. Tensile stress greatest in thin pavements with a stiff base layer and large positive temperature gradients subjected to tandem axle SLs. Fatigue damage was calculated for the critical cases using several damage models, and significant variation was found between models based on inputs used.KEYWORDS: Fatigue damagesuperloadsconcrete pavementsfinite element method Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingFunding for this study was provided by the Pennsylvania Transportation under [grant number 4400018535].

混凝土路面超载车辆造成的疲劳损伤

摘要超载重车辆(SLs)通常被定义为车辆总重(GVW)大于890千牛的车辆。SLs通常由独特的轴配置组成，可能会对路面造成重大损害。目前的研究主要局限于沥青路面上的水溶胶，因此对混凝土路面的影响还没有很好的确定。在这项研究中，混凝土路面的疲劳应力被量化为路面结构和SLs数据库，以确定导致疲劳损伤的关键条件。从有限元结果数据库中构建了一系列荷载脉冲，以确定板内峰值应力发展的条件和位置。在具有刚性基层和大正温度梯度的薄路面上，受串联轴SLs的拉应力最大。使用几种损伤模型计算临界情况下的疲劳损伤，发现不同输入值的模型之间存在显著差异。关键词:疲劳损伤、超载荷、混凝土路面、有限元法披露声明作者未报告潜在利益冲突。本研究的资金由宾夕法尼亚交通运输局提供[拨款号4400018535]。

期刊介绍： The international journal Road Materials and Pavement Design welcomes contributions on mechanical, thermal, chemical and/or physical properties and characteristics of bitumens, additives, bituminous mixes, asphalt concrete, cement concrete, unbound granular materials, soils, geo-composites, new and innovative materials, as well as mix design, soil stabilization, and environmental aspects of handling and re-use of road materials. The Journal also intends to offer a platform for the publication of research of immediate interest regarding design and modeling of pavement behavior and performance, structural evaluation, stress, strain and thermal characterization and/or calculation, vehicle/road interaction, climatic effects and numerical and analytical modeling. The different layers of the road, including the soil, are considered. Emerging topics, such as new sensing methods, machine learning, smart materials and smart city pavement infrastructure are also encouraged. Contributions in the areas of airfield pavements and rail track infrastructures as well as new emerging modes of surface transportation are also welcome.
