PERFORMANCE GRADE IMPROVER

 

Ravasol UPGRADE is a polymeric additive that modifies bitumen rheology to enhance high service temperature performances by boosting its softening point.  When dosed into the bitumen it improves PG (performance grade) complex modulus, maintaining unchanged low temperature values.

Heat-resistant and store stable when added into hot bitumen.

Due to its chemical composition it decreases PMB viscosity and when dosed together with SBS allows a sensible reduction of polymer content.

 

RECOMMENDED DOSAGE: 0.7 to 4.0 % by weight of bitumen.
