RISAnalyzing the Damage–Healing Performance of Asphalt Mixture from Macroscopic and Mesoscopic Scales
Publisher: American Society of Civil Engineers
Abstract: Owing to their self-healing ability, asphalt mixtures have great potential for improving the service life of asphalt pavement, and can play an important role in sustainable infrastructures. In this study, a semicircular ...
Frost-Resistance Assessment of C60 Concrete Based on a Fiber Bragg Grating Sensor
Publisher: ASCE
Abstract: In this paper, fiber Bragg grating (FBG) sensors were applied to investigate the frost resistance of C60 concrete. First, the growth of both the static and dynamic elastic modulus of C60 concrete with curing age was ...
Aerodynamic Losses of a Cambered Turbine Vane: Influences of Surface Roughness and Freestream Turbulence Intensity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of surface roughness and freestream turbulence level on the aerodynamic performance of a turbine vane are experimentally investigated. Wake profiles are measured with three different ...

Emission Characteristics of a Natural Gas Engine Operating in Lean-Burn and Stoichiometric Modes
Publisher: American Society of Civil Engineers
Abstract: To comply with the stringent Euro VI emission standards, two techniques have been proposed for natural gas engines, namely, lean-burn combustion with oxidation catalyst (OC) and stoichiometric combustion with three-way ...
Active Damping Design of Flexible Structures Based on SISO and SIMO Noncollocated Sensor-Actuator Velocity Feedback
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An active damping design technique based on single input velocity feedback is presented in this paper. The stability conditions for each individual mode in SISO and SIMO velocity feedback are ...
Eco-Hydrological Requirements in Arid and Semiarid Regions: Case Study of the Yellow River in China
Publisher: American Society of Civil Engineers
Abstract: The eco-hydrological requirements of a river are related to the health of the river. In recent years, changing climate and intensifying human activities have further aggravated water problems in the Yellow River. Considering ...
Emission Characteristics of a Natural Gas Engine Operating in Lean-Burn and Stoichiometric Modes
Publisher: American Society of Civil Engineers
Abstract: To comply with the stringent Euro VI emission standards, two techniques have been proposed for natural gas engines, namely, lean-burn combustion with oxidation catalyst (OC) and stoichiometric combustion with three-way ...
Investigation on Fracture Mode and Initiation Mechanisms of Cracks in Sandstone Disk Containing a Preexisting Flaw
Publisher: ASCE
Abstract: Determination of the fracture mode and the initiation mechanism of cracks emanating from preexisting flaws are of great significance for understanding the failure process of rocks. In this research, Brazilian tests were ...
Microstructure, Fatigue, and Self-Healing Properties of SBS-Modified Asphalt under Ultraviolet Radiation
Publisher: American Society of Civil Engineers
Abstract: Asphalt gradually deteriorates under the influence of ultraviolet light, especially at high altitudes or low latitudes, significantly shortening the service life of pavements. In this study, styrene-butadiene-styrene ...
