The objective of this paper is to analyze stress concentration in the concrete round circumference dowels for airport jointed rigid pavement system. Based upon ABAQUS, a 3D finite element model established by using continuum dowels, and actual interface conditions between concrete, slabs base are considered. status stresses including edge loading case corner obtained through structural response analysis. results indicate that maximum principal shear extremely high, magnitudes about 10.0MPa...
Dowel bar misalignment causes stress concentration in jointed concrete pavements, and misaligned dowel bars may lose their ability to transfer loads. To examine this problem, a damage plasticity (CDP) model method were implemented using ABAQUS evaluate its parameters. The CDP simulated the stress–strain relationship for tension compression specimens, was validated through experimental testing. A three-dimensional finite element of pavement developed, equivalent stress, plastic strain, under...
Recycled engine oil bottoms (REOBs) are widely used in asphalt binders for modification and cost saving. However, more early road failures have appeared on the pavements constructed with REOB-modified North America, leading to bans limits of its use interest REOB’s quantification binders. This study aims systematically introduce a quantifying method via liquid-state nuclear magnetic resonance (NMR) techniques. One base binder, two REOB resources, eight blend samples were measured by H1 NMR,...
The remaining life is usually taken into account for pavement maintenance or reconstruction. To determine the optimal reconstruction time of a certain composite airport pavement, authors used 3 kinds methods to predict life, respectively based on former Federal Aviation Administration (FAA) design standard called as Layered Elastic Design (LEDFAA), Airport Pavement Method China (APDMC) and Condition Index (PCI) regression model. According in-situ data Heavy Weight Deflectometer (HWD), PCI...
