RISEvaluation of Aging Characteristics of High-Viscosity Asphalt: Rheological Properties, Rutting Resistance, Temperature Sensitivity, Homogeneity, and Chemical Composition
Publisher: ASCE
Abstract: The purpose of this paper was to study the aging behaviors of high-viscosity asphalt (HVA). Three kinds of asphalt binders [base asphalt, styrene-butadiene-styrene-modified asphalt (SBSMA), and HVA] were treated with rolling ...
The Effect of the Accommodation Coefficient on Slider Air Bearing Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In solving the slider air bearing problem, both the Molecular Gas-film Lubrication (MGL) model and the Direct Simulation Monte Carlo (DSMC) model require the accommodation coefficient as input. ...
An Asperity Contact Model for the Slider Air Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As sliders fly closer and closer to the disks, asperity contact is inevitable due to the roughness on the sliders and the disks. A single asperity contact problem was solved using the molecular ...
Oxygen Transfer in High-Speed Surface Aeration Tank for Wastewater Treatment: Full-Scale Test and Numerical Modeling
Publisher: American Society of Civil Engineers
Abstract: Oxygen transfer is one of the key processes in the bioreactor. Herein a computational fluid dynamics model for the oxygen transfer in high-speed surface aeration tank has been developed and validated through a full-scale ...
Low-Temperature and Fatigue Characteristics of Degraded Crumb Rubber–Modified Bitumen Before and After Aging
Publisher: ASCE
Abstract: The high viscosity and poor storage stability of crumb rubber–modified asphalt (CRMA) can be partially addressed by the appropriate degree of degradation of the crumb rubber modifier. However, the low-temperature and fatigue ...
Influence of SBS on the Aging Properties of High-Content Terminal Blend Rubber Modified Asphalt
Publisher: ASCE
Abstract: The goal of this study was to investigate the effect of styrene-butadiene-styrene (SBS) polymer on the aging properties of high-content terminal blend rubber modified asphalt (HCTBMA). All asphalt was tested for chemo-rheological ...
Research of Underfill Delamination in Flip Chip by the J-Integral Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fracture mechanics approaches have been used to study reliability problems in electronic packages, in particular, adhesion related failure in flip chip assembly. It was verified in this work ...
Chemical, Physical, and Rheological Evaluation of Aging Behaviors of Terminal Blend Rubberized Asphalt Binder
Publisher: ASCE
Abstract: Terminal blend rubberized asphalt (TBRA) is widely used as binder of asphalt mixtures due to its technical characteristics of storage stability. However, its road performance deteriorates due to the aging process of TBRA. ...
Evaluation of Physicochemical and Rheological Properties of Terminal Blend Rubberized Asphalt Incorporating Polymer
Publisher: American Society of Civil Engineers
Abstract: Waste tires, used in combination with polymers, have been extensively employed in the construction of asphalt pavements. The performance of these hybrid asphalts varies depending on the manufacturing process, the characteristics ...
Analysis of Quantification and Mechanism of SBS Modifier in SBS-Modified Asphalt
Publisher: ASCE
Abstract: The determination of styrene-butadiene-styrene (SBS) content in SBS-modified asphalt (SBSMA) is crucial in road quality control. In this study, a polystyrene (PS)-based index, which is an alternative indicator for the ...
