Reflectance Spectra of Thermochromic Asphalt Binder: Characterization and Optical Mixing Model
(American Society of Civil Engineers, 2016)Asphalt pavement constructed with traditional asphalt binder, which features high solar absorbance, is characterized by high surface temperatures during summer. This causes undesirable performance degradation (i.e., due ... -
Laboratory Evaluation of Long-Term Draindown of Porous Asphalt Mixtures
(American Society of Civil Engineers, 2015)Long-term draindown is the term adopted in this study to describe the downward flow of binder in a porous asphalt mixture due to the force of gravity at high temperatures experienced during service, especially in warmer ... -
Effects of WMA Technologies on Asphalt Binder Blending
(American Society of Civil Engineers, 2016)Because of environmental and economical benefits, the paving industry has made attempts to incorporate recycled asphalt pavement (RAP) or recycled asphalt shingle (RAS) into warm mix asphalt (WMA). However, the low ... -
Silica Aerogel–Glass Fiber Composites As Fire Shield for Steel Frame Structures
(American Society of Civil Engineers, 2015)In this study, glass fiber silica aerogel composites were fabricated and used to protect steel frames against fire. Glass-fiber-coated silica aerogel was synthesized by immersing glass fibers into silica sol. Following gel ... -
Inorganic–Organic Hybrid of Lunar Soil Simulant and Polyethylene
(American Society of Civil Engineers, 2016)Inorganic–organic hybrid (IOH) lunar cements are processed by using a lunar soil simulant and polyethylene (PE). As the inorganic simulant grains are strongly held together by the PE binder, the IOH may be utilized as an ... -
