1. Description of the product
ORBITON 25/55-80 HiMA (“hard HiMA”) is designed for special courses requiring exceptional deformation resistance (parking lots for heavy vehicles, container terminals, etc.) and where very heavy, slow traffic takes place. Since this binder is very hard, it should be used only in justified cases and suitable site conditions need to be ensured. It should be clearly stated that ORBITON 25/55-80 HiMA is not a direct replacement for PMB 25/55-60 and is not intended for AC EME. For typical pavement constructions, ORBITON 45/80-80 HiMA is recommended instead of ORBITON 25/55-80 HiMA.
