RISEffective Reduction of Cement Content in Pavement Concrete Mixtures Based on Theoretical and Experimental Particle Packing Methods
Publisher: ASCE
Abstract: The effective reduction of cement content in pavement concrete without compromising its fresh, mechanical, and durability properties can lead to more economical and sustainable pavement engineering. Because a reduction in ...
Multiscale Characterization to Examine the Effects of Aggregate Properties on Aggregate-Paste Interphase in Cement Concrete Mixtures
Publisher: ASCE
Abstract: This study aims to test the effects of aggregate properties on the features of aggregate-paste interphase in portland cement concrete mixtures. The microstructural, chemical, and nanomechanical properties of the interphase ...
Linear Viscoelastic Analysis of Asphalt Mastics
Publisher: American Society of Civil Engineers
Abstract: The dynamic shear rheometer (DSR) is used to characterize linear viscoelastic properties of asphalt cement and asphalt mastic (asphalt cement with a filler that is smaller than 75 μm in size). The study focuses on using ...
Mechanistic Modeling to Evaluate Structural Performance of Bituminous Pavements with Inelastic Deformation and Fatigue Damage of Mixtures
Publisher: American Society of Civil Engineers
Abstract: This study modeled structural performance of bituminous pavements with inelastic deformation and fatigue damage. Two major distresses, namely rutting and fatigue damage, of typical bituminous pavements were modeled by ...
Damage-Induced Modeling of Elastic-Viscoelastic Randomly Oriented Particulate Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a model for predicting the damage-induced mechanical response of particle-reinforced composites. The modeling includes the effects of matrix viscoelasticity and fracture, both ...
Fatigue and Healing Characterization of Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: This paper investigates the effect of the processes on fatigue fracture and fracture healing during controlled-strain, dynamic mechanical analysis (DMA) testing. Sand asphalt samples were fabricated with two SHRP-classified ...
Damage-Induced Modeling of Asphalt Mixtures through Computational Micromechanics and Cohesive Zone Fracture
Publisher: American Society of Civil Engineers
Abstract: This paper presents a computational micromechanics modeling approach to predict damage-induced mechanical response of asphalt mixtures. Heterogeneous geometric characteristics and inelastic mechanical behavior were taken ...
Computational Constitutive Model for Predicting Nonlinear Viscoelastic Damage and Fracture Failure of Asphalt Concrete Mixtures
Publisher: American Society of Civil Engineers
Abstract: 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 ...
