Shifting the bitumen structure from sol to gel. F. Bonemazzi and C. Giavarini. J. Petrol. Sci. Engng., January 1999, 22(1--3), 17--24.
The viscoelastic model and rheometer measurements are utilized to reveal the microscopic structure changes from sol to gel of acid or air-treated bitumen. Stability studies have also been undertaken on bitumens modified with a new class of polymers (polypropylene heteroplastic copolymers) before and after physical (high temperature blowing) or chemical (acid addition) treatments. 20 refs.
