Mastering bitumen for better roads and innovative applications

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.
