About the Speaker:

Qing Lu is an associate professor of Civil and Environmental Engineering at the University of South Florida. The research focus includes the design and management of sustainable transport infrastructure, mainly road systems, pavement structures and asphalt materials. Deputy editor of Transportation Research Part D -- Transport and Environment, Chairman of the Academic Committee of China International Association of Infrastructure Professionals, member of ASCE EMI Pavement Mechanics Committee, And editorial board members of several magazines. He holds a Bachelor's degree in Highway and Urban Road Engineering from Southeast University, a doctorate in Civil engineering and a Master's degree in statistics from the University of California, Berkeley. Prior to joining the University of South Florida, he was a project scientist and laboratory at the University of California Pavement Research Center (UCPRC) Manager, California certified civil engineer.

Brief introduction of the lecture:

Porous asphalt mixture features a high permeability and is primarily used on pavement surface to reduce vehicle hydroplaning or stormwater runoff. The mixture may also offer additional functional and environmental benefits such as noise reduction through appropriate design. This talk presents recent research efforts in testing and analyzing porous asphalt mixture to improve its acoustic performance, durability, and environmental sustainability. Laboratory experiments were performed to evaluate the mixture performance in terms of permeability, surface texture, resistance to raveling, tensile strength, and sound absorption. A mechanistic-empirical model was developed for tire-pavement noise based on mixture design parameters. The potential of incorporating renewable or waste materials into the mixture was also evaluated.
