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. Ragaa Abdelhakim is an assistant professor at Tanta University, Egypt.
