Analytical Modeling of Three-Layered HMA Mixtures
(American Society of Civil Engineers, 2007)This paper presents the analytical modeling of three-layered hot mix asphalt (HMA) mixtures. Conventional HMA mixtures can be regarded as a two-layered composite with asphalt-coated aggregate particles dispersed in an ... -
Responses of Excess Pore Water Pressure in Soft Marine Clay around a Soil–Cement Column
(American Society of Civil Engineers, 2007)The soil ground treated by deep cement mixing (DCM) in the field normally consists of cement–soil mixed columns and untreated soils. Although many attempts have been made, research on the consolidation behavior of the ... -
Development of an Elastoviscoplastic Microstructural-Based Continuum Model to Predict Permanent Deformation in Hot Mix Asphalt
(American Society of Civil Engineers, 2007)Permanent deformation in hot mix asphalt is caused by a combination of densification (decrease in volume and hence increase in density) and shear deformation. The primary objective of this paper is to develop an ... -
Three-Dimensional Linear Behavior of Bituminous Materials: Experiments and Modeling
(American Society of Civil Engineers, 2007)The linear viscoelastic properties of bituminous mixtures are used to design pavement structure. Usually, only complex moduli -
Micromechanical Modeling of the Viscoelastic Behavior of Asphalt Mixtures Using the Discrete-Element Method
(American Society of Civil Engineers, 2007)This paper presents a methodology for analyzing the viscoelastic response of asphalt mixtures using the discrete-element method (DEM). Two unmodified (neat) and seven modified binders were mixed with the same aggregate ... -
Advanced Testing and Characterization of Asphalt Concrete Materials in Tension
(American Society of Civil Engineers, 2007)The modeling of asphalt concrete materials is currently handled using linear viscoelasticity (VE) and viscoplasticity (VP) with damage. Exploratory frequency sweep and creep and recovery test results indicate that the ... -
Unified DSC Constitutive Model for Pavement Materials with Numerical Implementation
(American Society of Civil Engineers, 2007)Need for unified and mechanistic constitutive models for pavement materials for evaluation of various distresses has been recognized; however, such models are not yet available. There have been efforts to develop unified ... -
Computational Constitutive Model for Predicting Nonlinear Viscoelastic Damage and Fracture Failure of Asphalt Concrete Mixtures
(American Society of Civil Engineers, 2007)A computational constitutive model was developed to predict damage and fracture failure of asphalt concrete mixtures. Complex heterogeneity and inelastic mechanical behavior are addressed by the model by using finite-element ... -
Viscoelastoplastic Damage Characterization of Asphalt–Aggregate Mixtures Using Digital Image Correlation
(American Society of Civil Engineers, 2007)This paper presents the research effort in which the viscoelastoplastic continuum damage (VEPCD) model is developed and calibrated for the behavioral prediction of asphalt–aggregate mixtures subjected to tensile stresses ... -
Clogging of Pervious Monolayers Subjected to Radial Flow
(American Society of Civil Engineers, 2007)Particle migration within porous networks often results in permeability reductions due to clogging. In many field applications, fluids and entrained particles travel radially toward producing wells. The nonhomogeneous ... -
Influence of Nonassociativity on Localization and Failure in Geomechanics Based on Gradient Elastoplasticity
(American Society of Civil Engineers, 2007)We present results of a parametric study on shearband formation in geomaterials, examining the influence of material dilatancy on shearband properties. The study is based on a new higher order continuum theory, called ... -
Diagnostic Curve Methods for Consolidation Coefficient
(American Society of Civil Engineers, 2007)Two new diagnostic curve methods, which do not require the implicit or explicit determination of initial or final dial gauge readings for primary settlement, are proposed for the identification of the consolidation ... -
Quadrilateral Isoparametric Shear Deformable Shell Element for Use in Soil-Structure Interaction Problems
(American Society of Civil Engineers, 2007)In the finite-element analysis of soil-structure interaction problems, shell elements are important to model structural components such as tunnel linings or sheet pile walls. In this paper the development, implementation, ... -
Effect of the Smear and Transition Zones around Prefabricated Vertical Drains Installed in a Triangular Pattern on the Rate of Soil Consolidation
(American Society of Civil Engineers, 2007)Soil disturbance caused by the installation of prefabricated vertical drains (PVDs) has a large impact on the rate of consolidation. It is essential in design to quantify this effect. In this paper, we investigate the ... -
General Axisymmetric Active Earth Pressure by Method of Characteristics—Theory and Numerical Formulation
(American Society of Civil Engineers, 2007)Active pressure for axisymmetric problem under general conditions is formulated and solved by an iterative finite difference solution of the characteristic equations in the present paper. A general lateral stress coefficient ... -
Validation of 3DFE Analysis of Rigid Pavement Dynamic Response to Moving Traffic and Nonlinear Temperature Gradient Effects
(American Society of Civil Engineers, 2007)The response of dowel jointed concrete pavements to the combined effect of nonlinear thermal gradient and moving axle load is examined using three-dimensional finite-element (3DFE) modeling. The 3DFE-computed response to ... -
Ultimate Bearing Capacity of Two Interfering Rough Strip Footings
(American Society of Civil Engineers, 2007)The ultimate bearing capacity of two interfering strip footings was determined by using the method of stress characteristics. The analysis was performed by choosing two different possible failure mechanisms. The variation ... -
Numerical Analysis of T-Bar Penetration in Soft Clay
(American Society of Civil Engineers, 2006)The penetration resistance of a cylindrical T-bar penetrometer in soft clay is affected by features such as anisotropy, high strain rates, and gradual strain-softening during passage of the T-bar. In order to evaluate these ... -
Degradation of a Granular Base under a Flexible Pavement: DEM Simulation
(American Society of Civil Engineers, 2006)Flexible pavements are composed by an asphalt concrete layer, granular base and subbase layers, and a natural subgrade. The granular materials forming part of the granular layers are subjected to static and dynamic loads ... -
