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. November 2013 – V07 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. 35/50 Before RTFOT Penetration @ 25°C, dmm Softening Point, °C 35/50 After RTFOT 35/50 + 35/50 + 35/50 20/30 15% SLN 15% SLN (EN 12591 (EN 12591 Before RTFOT After RTFOT specifications) specifications) 43 31 35 – 50 20 – 30 53,2 56,4 50 – 58 55 – 63 Resistance to hardening : Retained penetration, % Softening Point, °C 64,2 63 53 mini 55 mini 59 63,4 52 mini 57 mini November 2013 – V07 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.

November 2013 – V07 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 … Selenice Bitumi Sha Po box 8202 – Tirana – ALBANIA Tel: +355 (0) 44 50 25 54 Fax: +355 (0) 44 50 25 53 E-mail: [email protected] www.selenicebitumi.com
