1. Description of the product
ORBITON 10/40-65 modified bitumen modified bitumen is the hardest modified bitumen in the range of modified bitumens currently manufactured by ORLEN Group. Its very high softening point renders it suitable for high-stiffness-modulus mixture AC EME base and binder courses. It can also be used for conventional asphalt concrete mixtures. Results of tests of resistance to rutting of asphalt mixtures containing this type of bitumen demonstrate that it is suitable for pavements carrying slow and heavy traffic, such as parking lots, slow traffic lanes and crossroads. This type of bitumen is not recommended for use in wearing courses.

* – 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
