The use of Selenizza SLN 120® profoundly profoundly changes the rheological properties of the natural binder. Depending on the amount of Selenizza added and the grade of base bitumen, it is possible to accurately obtain the required penetration and / or softening temperature for the binder to be obtained.

An important factor of the Selenizza asphalt admixture is the increase in the hardness of the initial bitumen without changing the elastic properties of the resulting binder.
