Product Overview

Description

Bitumen 60-70:

Bitumen penetration grade  is semi hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements with below technical specification. It also mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Bitumen 60-70 is mostly used bitumen grade and basic material for all other bitumenious products.

Temperature vs stiffness relationship of bitumen is dependent on type of crude oil and its refining method. It used as a paving grade bitumen which is suitable for road construction and repair. It also used for production of asphalt pavements with below technical specification. This grade of bitumen is mainly used in manufacturing of hot mix asphalt for bases and wearing courses. It`s one of most used bitumen grades.

Softening point and penetration of bitumen 60/70

Application of bitumen penetration grade 60/70

Bitumen 60/70 is suitable for road construction and for the asphalt pavements with superior properties. This type of bitumen used in the manufacture of hot mix asphalt for bases and wearing courses and the main usage of this product is used in the road in mild regions. The bitumen is provided during the presses of oxidation of vacuum bottom in bitumen production units. Due to its medium air blowing and penetration, it is used in mild areas.
