Description of the product
ORBITON 65/105-60 modified bitumen is designed for use in hot mix wearing courses, within good mineral skeleton mixtures. It is produced using soft base bitumen with a high polymer content, which allows a product to be obtained with excellent low-temperature properties and elasticity. ORBITON 65/105-60 is characterised by higher penetration at 25°C in comparison to modified bitumen 45/80-65, and at the same time demonstrates high levels of cohesion and elasticity. The combination of those features renders the product a very good binder for thin-layered mixtures of non-continuous granulation. Such applications include PA, BBTM and AUTL mixes for thin wearing courses and SMA. Those are primarily special wearing courses and wearing courses used at low-temperature locations. This binder can also be used in bridge deck mixtures, whenever excellent elasticity of the binder is required.

* – change of mass may be a positive or negative value
** – depending on the final use, only one method for determining cohesion should be chosen. The cohesion determination by the Vialit method (EN 13588) should only be chosen for bitumen for surface treatment
NR – No Requirement
TBR – To Be Reported
