A performance grade of polymer - modified bitumen, according to SHRP specifications

Vasilica Beica, Mihai Dimonie

Abstract


This paper present some results obtained on the evaluation of various bituminous binders used in rehabilitation, modernization and maintenance works, involving the SHRP/SUPERPAVE equipments and specifications, based on the performance criteria, in conjunction with the classical methods as those involving the thermal susceptibility, Fraass breaking point and chemical composition. The paper also includes recommendations concerning the improvement of the performance of these binders, by modification either with SBS or reactive polymers.
