Book excerpt: The proper understanding of tire-pavement interaction is important for the accurate analysis of load-induced stresses and strains in the pavement structure. This dissertation focuses on the analysis of the mechanism of tire-pavement interaction and the effect of tire-pavement interaction on pavement responses using a decoupled modeling approach. First, an air-inflated three-dimensional (3-D) finite element (FE) tire model was built and the interaction between a tire and a non-deformable pavement surface was simulated. The tire is modeled as a composite structure including rubber and reinforcement. The steady-state tire rolling process was simulated using an Arbitrary Lagrangian Eulerian (ALE) formulation. The developed tire-pavement interaction model is used to evaluate the mechanism of load distribution at the tire-pavement interface under various tire loading and rolling conditions. After that, a 3-D FE model of flexible pavement was developed to analyze pavement responses under various loading scenarios. This model utilizes the implicit dynamic analysis, simulates vehicular loading as a continuous moving load, and incorporates 3-D contact stresses at the tire-pavement interface. In the pavement model, the asphalt layer is modeled as a linear viscoelastic material and the granular base layer is modeled as a nonlinear anisotropic material. The FE pavement model was used to analyze critical pavement responses in thin and thick asphalt pavements considering different damage mechanisms. This dissertation concludes that knowledge of tire-pavement contact stress distributions is critical for pavement response prediction. Most importantly, the non-uniform distribution of vertical contact stresses and the localized tangential contact stresses should be considered in the mechanistic-empirical pavement design. The contact stress distributions at the tire-pavement interface are affected by vehicle loading (wheel load and tire inflation pressure), tire configuration (dual-tire assembly and wide-base tire), vehicle maneuvering (braking/acceleration and cornering), and pavement surface friction. Therefore, pavement damage should be quantified using accurate loading inputs that are represented by realistic tire-pavement contact stress distributions. Thin and thick asphalt pavements fail in different ways. Multiple distress modes could occur in thin asphalt pavements, including bottom-up fatigue cracking and rutting in each pavement layer. It was found that the interaction between the viscoelastic asphalt layer and the nonlinear anisotropic granular base layer plays an important role for the stress distribution within a thin asphalt pavement structure under moving vehicular loading. In thick asphalt pavements, near-surface cracking is a critical failure mechanism, which is affected by the localized stress states and pavement structure characteristics. Particularly, the effect of shear stress on the formation of near-surface cracking at multi-axial stress states is important and can not be neglected, especially at high temperatures.

Download or read book Coupled System Pavement - Tire - Vehicle written by Michael Kaliske and published by Springer Nature. This book was released on 2021-07-02 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes research being pursued within the Research Unit FOR 2089, funded by the German Research Foundation (DFG), the goal of which is to develop the scientific base for a paradigm shift towards dimensioning, structural realization and maintenance of pavements, and prepare road infrastructure for future requirements. It provides a coupled thermo-mechanical model for a holistic physical analysis of the pavement-tire-vehicle system: based on this model, pavement structures and materials can be optimized so that new demands become compatible with the main goal – durability of the structures and the materials. The development of these new and qualitatively improved modelling approaches requires a holistic procedure through the coupling of theoretical numerical and experimental approaches as well as an interdisciplinary and closely linked handling of the coupled pavement-tire-vehicle system. This interdisciplinary research provides a deeper understanding of the physics of the full system through complex, coupled simulation approaches and progress in terms of improved and, therefore, more durable and sustainable structures.

Available in PDF, EPUB and Kindle. Book excerpt: Vehicles pass their loads through tires onto pavements. Traditionally, the vertical contact pressure is assumed to uniformly distribute in a rectangle or circular area, whereas the shear contact pressure is ignored in pavement design. Experiments have demonstrated that the interaction between the tire and the pavement surface is very complicated. The contact area is not a regular shape and the distribution of contact pressure is not uniform. However, experimental approaches to measure contact pressure are usually time and energy consuming, whereas the results are subject to errors introduced by measurement sensors. On the other hand, numerical simulation can describe the interaction between tire and pavement surface under all circumstances, such as various driving conditions, different tread types, and so on. In this paper, a three-dimensional finite-element model for tires was developed. The model was validated by the static test data. Then the interactions of different tires with pavement were analyzed, including the vertical and shear contact-pressure distributions on tires and on pavement surfaces. The influences of pavement friction and load level on the contact-pressure distributions of tires and pavement were investigated as well. It was found that vertical and shear contact pressures on tires and pavement were quite different when the type of tire or the friction changed. The contact-pressure distribution was found not uniform and the shape of contact area changed as the load level varied. The complicated interactions between different tires and pavement indicate that sophisticated tire models are necessary to obtain more accurate pavement responses.

This book was released on 2017 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of pavement responses is important for better understanding of pavement performance and accurate estimation of pavement service life. This dissertation aims to study flexible pavement responses using forward and inverse analysis. The first objective is development of axisymmetric finite element (FE) models that can simulate FWD loading on the pavement system. After that, the backcalculation of pavement layer moduli from FWD testing was studied by means of soft computing techniques such as Artificial Neural Networks (ANNs) and Genetic Algorithms (GA). The axisymmetric FE models were used to generate a synthetic database. The ANN-GA backcalculating program is developed to assess existing pavement condition after the training and verification using the synthetic database. The second objective of this dissertation is to investigate airfield flexible pavement responses under aircraft loading in consideration of the realistic aircraft tire-pavement interaction. An advanced three-dimensional (3-D) finite element (FE) model was developed to simulate heavy aircraft loading with high tire pressure. The aircraft loading was simulated as moving wheels having non-uniform contact stress distributions. Different tire rolling conditions caused by aircraft ground maneuvering were simulated, including free rolling, full-braking, and turning. The multi-wheel aircraft loading was modeled in two-wheel, four-wheel and six-wheel assembly. The analysis concludes that FWD deflections were affected by dynamic analysis, temperature gradient, bedrock depth, asphalt layer delamination, viscoelasticity, and unbound material nonlinearity. After validated with the field measurements in the long-term pavement performance program (LTPP) database, the developed ANN-GA program can be used to obtain damaged dynamic moduli of asphalt concrete and evaluate in-situ pavement conditions from structural point of view, which facilitates pavement overlay design procedure using Mechanistic-Empirical Pavement Design Guideline (MEPDG). The investigation on airfield flexible pavement emphasized the importance of considering non-uniform tire contact stresses and temperature profiles in airfield pavement analysis. For the aircraft ground maneuvering, aircraft braking or turning significantly increases shear failure potential in asphalt layer. The analysis of stress states would facilitate evaluation of the shear failure potential at airfield asphalt pavements. Finally, the investigation on multi-wheel aircraft loading indicates that the six-wheel gear configuration would cause more fatigue cracking and near-surface cracking potential than dual-wheel and four-wheel gears.
