Sustainable Solutions for Railways and Transportation Engineering

Sherif El-Badawy is associate professor at Mansoura University, Egypt. He serves as the director of Highway and Airport Engineering Laboratory, Director of the Center of Scientific, Experimental, and Technical Services, Mansoura University. He received a BSc degree with honor in Civil Engineering and MSc from Mansoura University, Egypt. Dr. El-Badawy pursued his PhD Degree at Arizona State University (ASU), USA in 2006. He worked as a Postdoctoral Research Associate at ASU from June 2006 until July 2007 and as a Research Fellow at University of Idaho from December 2009 until January 2012. He has more than 20 years of experience in pavement structural analysis, design and characterization. Dr. El-Badawy has participated in several state and national projects during his employment in the US. He was one of the team members under Professor Witczak in the NCHRP 1-37A and 1-40D Projects which focused on the development of the Mechanistic-Empirical Pavement Design Guide (MEPDG). He serves as a TRB Committee Member on Flexible Pavement Design (AFD60) since April, 2012. He is an elected board member of the Middle East Society of Asphalt Technologists (MESAT), a member of the International Geosynthetic Society (IGS), Transportation and Traffic Society (TTS), International Association of Computer Science and Information Technology (IACSIT), and Chi-Epsilon Honor Society. He developed and taught many undergraduate and postgraduate course in USA and Egypt. His research interest focuses on pavement material characterization and modeling, Mechanistic-Empirical pavement design methods, and traffic characteristics. Dr. EL-Badawy was the Chief Editor of the ASCE GPS "Innovative Technologies for Severe Weathers and Climate Changes". Through research and graduate advising, he published more than 70 technical publications and reports. Jan Valentin, Ph.D.: Active in the civil engineering (focus on pavement and road engineering) form more than 15 years. Since 2004 employed by Faculty of Civil Engineering, Czech Technical University in Prague. Presently deputy head of the Department of Road Structures and senior researcher. Part time also working as a specialist for the international company HOCHTIEF. He got his Ph.D. from CTU in Prague focusing on cold recycling performance characterization in 2009. His main areas of research and scientific interest are: recycling, warm mix asphalts, modification of bitumen incl. rubber, performance testing of bitumen and asphalt mixtures focusing actually mainly on deformation behavior. He is further interested in PPP schemes and in introducing digitalization to the road construction industry in the Czech Republic. Jan represent Czech Republic in the HSE committee of European Asphalt Pavements Association, he is a member of IASS and member of some TC within RILEM.
