ORBITON 45/80-65

Reference standard: PN-EN 14023:2011/Ap2:2020-02

Description of the product

ORBITON 45/80-65 modified bitumen is designed for use in wearing courses and for special applications. It is characterised by very high elasticity, high softening point and favourable characteristics in low temperatures. The high polymer content makes it difficult to incorporate in thin layers in adverse weather conditions (quick stiffening of layer, compaction problems). The high softening point and modification level render it suitable for application in locations where high tensile strength and fatigue resistance are necessary in combination with excellent low-temperature properties. ORBITON 45/80-65 modified bitumen has been primarily designed for application in wearing courses, as well as for porous asphalt PA.​

* – 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
