ROSIN OIL-MODIFIED BITUMEN AND THE BITUMINOUS COMPOSITION CONTAINING THEREOF

摘要

A rosin oil-modified bitumen compound having a significantly reduced viscosity compared to the conventional bitumen at same temperature, yet providing the bituminous composition of comparable indirect tensile strength and performance is disclosed. The bituminous composition made of the disclosed modified bitumen allows the production and application at lower temperatures than the conventional bituminous composition, and thereby a reduction in energy consumption and a lower emission level of organic volatiles and fumes.
