RISResearch on Permanent Deformation of Asphalt Mixture by Triaxial Repeated Load Test
Publisher: American Society of Civil Engineers
Abstract: Triaxial repeated load permanent deformation tests of AC13F, AC13C, AC16 and AC20 under interim haversine loading were conducted. The flow number was selected as an evaluation index to investigate the influences of asphalt ...
Effects of Material Design Parameters on Mechanical States of Bridge Deck Pavement
Publisher: American Society of Civil Engineers
Abstract: Bridge deck pavement is suffered from more complicated stresses than ordinary pavement, and mechanical states of the paving layers are influenced by material design parameters. After mechanical computation, the effects of ...
Micromechanical Analysis on Viscoelasticity of Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: Mori-Tanaka equivalent inclusion micromechanics theory was employed to investigate the viscoelasticity of asphalt mixture. Asphalt mixture was regarded as composites which treated coarse aggregate as a rigid inclusion and ...
Analysis of Asphalt Pavement Rut Based on Elastic-viscoplastic Theory
Publisher: American Society of Civil Engineers
Abstract: The elastic-viscoplastic theory was applied to research the permanent deformation of asphalt mixture, and a creep model was adopted for its good agreement with actual result. ABAQUS, the finite element modeling technique, ...
Research on Propagation and Fatigue Life of Asphalt Pavement Surface Crack
Publisher: American Society of Civil Engineers
Abstract: Focusing on the severity of asphalt pavement surface crack, a finite element analysis model of 20-node isoparametric elements was established with the commerce FEM software ABAQUS based on fracture mechanics theory. The ...
Numeric Analysis of Friction Contact between Tread and Flexible Pavement
Publisher: American Society of Civil Engineers
Abstract: A finite element analysis model including rubber tread and flexible pavement was established by FEM software ANASYS and friction contact problem between tread and flexible pavement was numerically analyzed. The deformational ...
Enhancement of Interfacial Thermal Conductance of SiC by Overlapped Carbon Nanotubes and Intertube Atoms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new way was proposed to enhance the interfacial thermal conductance (ITC) of silicon carbide (SiC) composite through the overlapped carbon nanotubes (CNTs) and intertube atoms. By nonequilibrium molecular dynamics (NEMD) ...
