1. Description of the product
ORBITON 45/80-80 HiMA (“medium HiMA”) is suitable for all asphalt layers of flexible pavements: base courses, including perpetual pavements, binder courses and wearing courses subject to very high loads. This universal binder combines elasticity with a very good rutting resistance.
2. Properties
Division based on types and requirements for highly modified bitumen in Poland acc. to National Annex NA, table NA.2, to standard PN-EN 14023:2011/Ap2:2020-02
