RISEffect of Amorphous Alloy Fiber on the Mechanical Properties of Ultrahigh-Performance Concrete by Nano-SiO2 Surface Modification
Publisher: American Society of Civil Engineers
Abstract: AbstractAmorphous alloy fiber-reinforced concrete (AAFRC) demonstrates superior tensile strength
and corrosion resistance compared to steel fiber-reinforced concrete. However, the
weak interfacial bonding between amorphous ...
Modeling of Axial Symmetric Flow Structure in Gas–Solids Risers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pneumatic transport of solids in a riser has a unique nonuniform flow structure, characterized by the core solids acceleration and the wall solids deceleration along the riser, which causes the downflow of solids and hence ...
Influence of Paraffin on the Microproperties of Asphalt Binder Using MD Simulation
Publisher: American Society of Civil Engineers
Abstract: Previous research has proved that paraffin has a negative effect on the mechanical properties of asphalt binder; however, until now there are very few studies on the fundamental mechanisms on a microscale. To study the ...
Asphalt Fume Exposures by Pavement Construction Workers: Current Status and Project Cases
Publisher: American Society of Civil Engineers
Abstract: Workers involved in asphalt pavement construction are exposed to asphalt fumes. The adverse health effects of asphalt fumes have long been recognized; however, there is still a lack of consistent and systematic approaches ...
Evaluation of Polishing Behavior of Fine Aggregates Using an Accelerated Polishing Machine with Real Tires
Publisher: American Society of Civil Engineers
Abstract: The long-term durability of both coarse and fine aggregate significantly affects the mechanical performance of asphalt pavements. Extensive investigations of aggregate durability have been conducted on coarse aggregate in ...
Development of a Three Degrees-of-Freedom Tendon-Sheath-Driven Upper Limb Exoskeleton With Sliding Mode Admittance Control for Microlaryngoscopic Surgery Assistance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Microlaryngoscopic surgery requires surgeons to maintain elevated arm postures for extended periods, leading to muscle fatigue, tremors, and reduced precision. Although upper-limb exoskeletons have been widely ...
Fatigue and Nonlinear Performance Characterization of Asphalt Mastics: A Combined Approach
Publisher: American Society of Civil Engineers
Abstract: AbstractAsphalt mastics, composed of a bitumen matrix and fillers, play a vital role in the
fatigue failure of asphalt mixtures. However, the mechanisms by which fillers influence
the fatigue properties of asphalt mastics ...
Influence of Temperature on the Mechanical Response of Asphalt Mixtures Using Microstructural Analysis and Finite-Element Simulations
Publisher: American Society of Civil Engineers
Abstract: Asphalt pavements are commonly used for highways and airport runways. In pavement design and analysis, environmental factors such as temperature need to be taken into account to accurately predict the service life of asphalt ...
Polymer Modification of Asphalt with Recycling By-Products of Polyurethane Foam as Asphalt Extender
Publisher: American Society of Civil Engineers
Abstract: AbstractWaste polyurethane (PU) can be degraded into polyols for recycling through alcoholysis,
effectively addressing environmental pollution and solid waste management challenges.
However, substantial byproducts of ...
