Bitumen Penetration Grade 50/70 is a standard penetration grade Bitumen usually used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties.
This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.
Application of Bitumen Penetration Grade 50/70
The bitumen penetration grade 50/70 is a semi-hard penetration grade, with penetration between 50 and 70. Which is mostly used in road construction, asphalt pavement, and manufacturer of hot-mix asphalt.
The penetration bituminous asphalt with high penetration numbers which are soft, mostly used in cold weather conditions and hard bituminous asphalt (low penetration number) can be used for warm weather conditions.
Bitumen 50/70 Specification
Kiapetro guarantees that the Bitumen Grade 50/70 is produced in compliance and conformity to International of European Standard DIN EN 12591:99, also meets the requirements of the following specification.
