when the ratio of EvothermTM is increased, viscosity and softening point is decreased.
On the other hand, penetration is increased.
At 1.8%wt of EvothermTM is the ratio which bitumen is still on grade.
As compared with the performances of the each additives for warm mix bitumen, EvothermTM has viscosity and softening point lower than other additives, but on the other hand it has highest penetration.
