The lectures will be given by Prof. Jean-François Corté
Professor Jean-François Corté graduated from the Polytechnic University of Paris, France, the French National Road and Bridge College and the University of California, Berkeley. He was the Secretary-General of the former World Road Association (PIARC) and was the Director of the National Highway Network Management and Construction Center of the French Ministry of Transport and the Technical Director of Road Engineering in the French Central Road and Bridge Laboratory (LCPC, now IFSTTAR). Professor JF Corté's main research areas involve: High modulus asphalt and mixture, asphalt pavement modeling technology, subgrade pavement engineering, road material testing and analysis technology, etc. He is an authoritative expert and well-known scholar in the field of French road engineering. He is the editor-in-chief of several French geotechnical and highway standards; the legal representative of the CEN TC227 writing group of the European Technical Specification; the French representative of the European Technical Specification CEN TC336 writing group.
