​Prof Wynand Steyn is Head of Department and professor of the Department of Civil Engineering, and Chair of the School of Engineering at the University of Pretoria. He is a professionally registered pavement engineer with a research interest in vehicle-pavement interaction, accelerated pavement testing, pavement engineering, pavement materials, Civiltronics and instrumentation. He completed both his undergraduate and graduate studies at the University of Pretoria, South Africa. He has authored, co-authored and edited 41 journal papers, 21 book chapters (author / co-author / editor) and 109 conference papers. He is Associate Editor of the International Journal for Pavement Engineering and the International Journal of Pavement Research and Technology, andhas a B3 National Research Foundation (NRF) rating.He is a Fellow of the South African Institution of Civil Engineers, Fellow of the South African Academy of Engineering (SAAE) and an adjunct professor at the Chang’an University inXian, and the Shandong Jianzhu University in Jinan, China.Dr. Wang Zhixin is a senior engineer of Hainan Province Hydrogeological Engineering Geological Survey Institute. He is also a member of National First-Class Construction Engineers in construction engineering and a member of Registered Civil Engineers in the geotechnical field. He engages mainly in geotechnical engineering survey design and construction, geological disaster assessment and construction, underground engineering, marine geotechnical engineering, water and soil conservation and other engineering and research work. He has supervised and led over five National Natural Science Foundation and Provincial Natural Science Foundation projects, as well as more than ten Provincial key engineering projects. He has published more than ten papers.Glynn Holleran is a research fellow at the University of Auckland in the Civil and environmental engineering department. He is ManagingDirector of Advanced Asphalt technologies New Zealand and a registered engineer of Engineering New Zealand, A Chartered Chemist of the Royal Australian Chemical Institute and American Chemical Society. He is a life member of the association of Asphalt Pavement Technologists USA. He has worked in materials science and engineering since 1977 in all continents, including eastern Europe, Asia, China, Middle East, Africa, North America, South America, and Australasia, and he has many published journal and conference papers. His specialty is polymer chemistry and rheology and performance asphalt mix design, pavement design, bitumen chemistry ( former bitumen consultant to Mobil oil international ), and refining. He has been associated with FHWA projects in the USA and government projects in New Zealand. He is currently working on an MBIE government project on electric vehicle charging. Current interests are pavement preservation and toll roads in India and work with Texas A&M in Qatar. Glynnis a reviewer for several ASCE and other international journals. He has had several patents with Mobil Oil, and a current patent in polymer science in India is under review.
