Influence of Rubber Pre-Processing on the Rheological

Mixing of SBS and crumb-rubber in bitumen requires high temperatures, as well as long mixing times and high shear deformations, for producing a satisfactory dispersion. Rubber pre-treating leads to a more efficient mixing process with reduced mixing time
