Indoor and Outdoor Aging Behaviors of a Heat-Reflective Coating for Pavement in the Chongqing Area
Publisher: American Society of Civil Engineers
Abstract: The indoor and outdoor aging behaviors of a heat-reflective coating were studied regarding the problems derived from aging and reduced cooling effects. A one-year natural exposure test of the coating on a roof and on ...
Molecular Dynamics Simulation to Investigate the Influence of SBS on Molecular Agglomeration Behavior of Asphalt
Publisher: American Society of Civil Engineers
Abstract: Styrene-butadiene-styrene (SBS) modified asphalt has been used in many road projects for its good performance at high and low temperatures. However, there was no final conclusion whether SBS could change the chemical ...
Cooling Principle Analyses and Performance Evaluation of Heat-Reflective Coating for Asphalt Pavement
Publisher: American Society of Civil Engineers
Abstract: In the experiment, a heat-reflective coating (HRC) was applied to the surface of asphalt pavement. The coating temperature reduction principle and the mechanism to mitigate the urban heat island effect (UHI) were explored ...
g-C3N4/TiO2 Photocatalyst and Its Performance of NO Degradation in Emulsified Asphalt
Publisher: American Society of Civil Engineers
Abstract: This study prepared one g-C3N4/TiO2 composite photocatalyst by calcinating a mixture of melamine and nano TiO2, and then mixed it with asphalts to photodegrade the NO produced by automobile exhaust. The melamine and TiO2 ...
