ORBITON 25/55-60

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

Description of the product

ORBITON 25/55-60 modified bitumen is one of the most popular modified bitumen types. It is used in asphalt concrete base and binder courses and for high-stiffness modulus asphalt concrete AC EME1 (at the required stiffness modulus of 14 000 MPa). It can also be used in wearing, binder and base courses made of SMA at sections carrying slow and heavy traffic and in mastic asphalt MA.

* – 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
