RISDiffusive Dynamics and Structural Organization of Moisture in Asphaltic Materials Based on Molecular Dynamics Simulation
Publisher: ASCE
Abstract: Understanding the diffusion of moisture in asphaltic materials is crucial because it yields key insights into the moisture-induced damages of asphalt pavement. In this work, the molecular dynamics simulation technique was ...
Temporal Homogenization Modeling of Viscoelastic Asphalt Concretes and Pavement Structures under Large Numbers of Load Cycles
Publisher: American Society of Civil Engineers
Abstract: This paper aims to introduce a highly efficient computational model compared to the current cycle-by-cycle simulation strategy to compute the viscoelastic responses of asphalt concretes and pavement structures under large ...
Weak Form Equation–Based Finite-Element Modeling of Viscoelastic Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: The objective of this study is to demonstrate using weak form partial differential equation (PDE) method for a finite-element (FE) modeling of a new constitutive relation without the need of user subroutine programming. ...
Microstructure-Based Inherent Anisotropy of Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: Asphalt mixtures have been demonstrated to be anisotropic materials in both laboratory and field tests. The anisotropy of asphalt mixtures consists of inherent anisotropy and stress-induced anisotropy. In previous work, ...
Characterizing Permanent Deformation and Fracture of Asphalt Mixtures by Using Compressive Dynamic Modulus Tests
Publisher: American Society of Civil Engineers
Abstract: Permanent deformation and fracture may develop simultaneously when an asphalt mixture is subjected to a compressive load. The objective of this research is to separate viscoplasticity and viscofracture from viscoelasticity ...
Mechanistic Modeling of Fracture in Asphalt Mixtures under Compressive Loading
Publisher: American Society of Civil Engineers
Abstract: When an asphalt mixture is subjected to a destructive compressive load, it experiences a sequence of three deformation stages, as follows: the (1) primary, (2) secondary, and (3) tertiary stages. Most literature research ...
Anisotropic Viscoelastic Properties of Undamaged Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: A test protocol and a data analysis method are developed in this paper on the basis of linear viscoelastic theory to characterize the anisotropic viscoelastic properties of undamaged asphalt mixtures. The test protocol ...
Weak Form Equation–Based Finite-Element Modeling of Viscoelastic Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: The objective of this study is to demonstrate using weak form partial differential equation (PDE) method for a finite-element (FE) modeling of a new constitutive relation without the need of user subroutine programming. ...
Promoting Public Participation in NIMBY Facilities' EIA in Urban Planning: An Evolutionary Game Model
Publisher: ASCE
Abstract: As a way of empowerment, public participation has gained extensive application to address not-in-my-backyard (NIMBY) issues in short-term one-off and long-term strategic urban planning. Promoting public participation in ...
Predicting High-Cycle Fatigue Damage in Viscoelastic Bituminous Materials Using the Time–Strain Superposition Principle
Publisher: American Society of Civil Engineers
Abstract: Fatigue crack damage is a primary pavement failure; however, it is an extreme challenge to predict the fatigue damage under high-cycle loading. This paper develops a time–strain superposition principle based on the free ...
