Rheological investigation of asphalt and bitumen :: Anton

Rheological investigation of asphalt and bitumen. Bitumen is a refined residue from crude oil distillation. It is a complex mixture containing many diverse petrochemical components. Asphalt is a mixture of bitumen and mineral components, with bitumen serving as a binder. In some countries (like the USA), however, the terms asphalt and bitumen
