During the four coming weeks, best experts in bitumen will bring you their knowledge and experience to build a strong understanding of today’s realities and new perspectives on the future of bitumen. Total is the European leader on bitumen markets. Innovation has always been the key to sustainability and durability in the products they develop. Their main objective here is to share technical knowledge and experience to insure bitumen are being used in the most effective and efficient ways for their different applications in road works. Ecole des Ponts, France oldest engineering school, remains very much in the present, as it has always been, in training engineers in order to meet the needs of our society and citizens in key areas such as transport housing and urban services, but also in fields like energy, environment, climate sciences, land-use planning and sustainable development. Nineteen world recognized experts on bitumen are contributing to this MOOC. The idea is to provide the broadest prism on this topic area with speakers coming from research, industry and end users.

Syllabus

Bitumen market, generalities, the manufacture of bitumen, transport, uses of bitumen, main developments and alternatives

Origins, history, definition, terminology | market per geographical areas, figures of consumption, main producers, capacities of production, ranking, main flows between areas | global development of motorised transport - cars, airplane - was one of the single most development of 20-21st centuries | global development of buidings, roofing and other applications of bitumen | difference between bitumen, cement and tar coal. Advantages and drawback of each | different ways of transport of bitumen and present the supply chain diagram and restrictions. ADR Regulation | sampling, handling and safety principles. Hazard from handling hot bitumen is thermal burns.
