Selenizza® SLN : a naturally occurring asphalt additive for producing high performance bituminous mixtures
Our product conforms to EN 13108-4 Appendix B Table B2
The additive Selenizza® SLN is compatible with all types of bitumen and its asphaltene content confers to bituminous mixes exceptional rheological and mechanical properties.
It can be blended directly with the hot bitumen in tanks, but usually, it is added during the asphalt mixing process (in the mixer for the discontinuous asphalt plants, or in the recycling ring for the continuous plants).
Depending on the added quantity of Selenizza SLN and on the characteristics of base bitumen as well, it is possible to obtain precise penetration and R&B softening point values of the resulting binder.
Its acidity index enhances the adherence of the constituents of mix asphalt. Selenizza® is completely and uniformly miscible with base bitumen. The resulting high performance asphalt mixes are homogenous and ensure better workability.
