RISA Model of Pyrolysis Carbon Black and Waste Chicken Feather Using a Response Surface Method in Hot-Mix Asphalt Mixtures
Publisher: ASCE
Abstract: Research on waste tire pyrolysis carbon black (PCB) in bitumen mixtures indicates that it has excellent high-temperature rutting resistance; however, the degradation of low-temperature crack resistance and water stability ...
Effect of Magnesium Ions on the Mechanical Properties of Soil Reinforced by Microbially Induced Carbonate Precipitation
Publisher: ASCE
Abstract: Microbially induced carbonate precipitation (MICP) is a new foundation treatment technology, which can improve the mechanical properties of soil. In this study, sand specimens containing different magnesium/calcium ion ...
Development of a Generalized Slip Surface Generation Model and Stress Calculation Method for Limit-Equilibrium Analysis of Slopes
Publisher: American Society of Civil Engineers
Abstract: This study introduces a generalized slip surface (GSS) based on the Mohr–Coulomb strength criterion, which encompasses various types of slip surfaces. It also presents a novel approach for multisegment GSSs in layered ...
Uncertainty Quantification on the Cooling Performance of a Transonic Turbine Vane With Upstream Endwall Misalignment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With increasing aerodynamic and thermal loads, film cooling has been a popular technology integrated into the design of the modern gas turbine vane endwall, especially for the first-stage vane endwall. A staggering amount ...
Microstructure of Alkali-Activated Slag in Ultralow Temperature Environments
Publisher: ASCE
Abstract: In this study, the changes in the phase and microstructure of alkali-activated slag (AAS) in ultralow-temperature environments (−170°C) was experimentally studied by means of X-ray diffraction (XRD), Fourier transform ...
Mechanism and Performance of SBS Polymer Dry-Modified Asphalt Mixture with PCB and TPO from Waste Tires
Publisher: ASCE
Abstract: Based on the efficient resource utilization of scrap tires, pyrolysis carbon black (PCB), and pyrolysis oil of waste tire (TPO), scrap tires’ products were treated using dry styrene-butadiene-styrene (SBS) polymer modification ...
Factors Affecting the Properties of PCB-Modified Asphalt
Publisher: ASCE
Abstract: Waste tire pyrolysis has the advantages of economy, environmental protection, and high energy conversion rate; however, there is little research on the application of pyrolysis carbon black (PCB), which accounts for a high ...
