Packaging Description
The finished Selenizza SLN ® is delivered solid and cold in various forms:
-
pellets (4-12 mm) or powder (0-5 mm), treated with an anti-caking agent to prevent
aggregation in mass, conditioned in big-bags from 0.8 to 1.4 tons or in fusible plastic
bags of 15 kg or of a tailored weight for a dedicated customer.
Other packaging could be produced on demand depending on quantity.
The Selenizza SLN® is introduced either directly in the hot bitumen storage tanks or in
preference in the asphalt mixer during batch preparation or through the recycling ring
or the filler introduction tube in continuous asphalt plants.
Usual increase of asphalt mixing temperature is required for appropriate compaction
according the targeted grade.

Modification of pure bitumen
The Selenizza SLN® is used to modify the rheological properties of the base bitumen.
Depending on initial base bitumen grade and percentage of Selenizza SLN ® added in the
base bitumen, the all range of hard bitumen from 35/50 to 10/20 could be obtained. The
addition of the natural bitumen from Selenice in penetration grade bitumen like 50/70
or 35/50 leads to the production of 35/50, 20/30 or 10/20, without significant influence on
binder ageing properties.

Modification of asphalt mix
The Selenizza SLN® is mainly used as additive to improve the asphalt mix design
performances on modulus, puncturing and rutting and so to produce BBME béton bitumineux à module élevé and EME - enrobes à module élevé (according
the EU standard EN 13108-1 "Bituminous mixtures, Material specifications,
Asphalt concrete").
For information purpose, some mix design studies at laboratory level are listed here below.

Depending on mix design, targeted performances and mix optimization, it is possible to
reach the BBME and EME specifications on a tailored mode by using conventional
penetration grade 35/50 with the appropriate addition of Selenizza SLN® during the
preparation of the bituminous mixture in the in the mix design leads plant.

Gains from the use of Selenizza SLN®
The addition of Selenizza SLN® in mix design leads to:
- Reduction of the penetration of the bituminous binder
- Increase in the softening point and the viscosity of the binder
- Increase of the modulus of asphalt mixes
- Improvement of the resistance of asphalt mixes to the permanent deformation,
puncturing and rutting
- Reduction of the sensitivity of the asphalt mix to hot temperature
- Increase in asphalt mixes lifetime
possible decrease of asphalt layers thickness
Applications of Selenizza SLN®
- Production of high modulus asphalt mixes for heavily loaded pavements such as
highways, bus lanes, roundabouts, harbour and industrial platforms, airports …
- Production of high resistance mastic asphalt mixes for stressed bituminous
layers such as waterproofing layers on bridges, footpath in cities …
