Bitumen 85/100

Definition of Bitumen 85/100

Bitumen  85/100 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. Penetration Grade Bitumen supplied by CARBOKIMCo. is petroleum-grade bitumen, manufactured from fractional/vacuum distillation of crude oil. The Bitumen supplied by RABIT Trading Co. This bitumen is produced through aeration on vacuum bottom (the raw material used for making bitumen left in the vacuum distillation column in oil refineries) in bitumen production units. Its penetration grade (the measure of bitumen hardness) is between 85 to 100.

Properties of Bitumen 85/100

Origin and Manufacturing Process

It is derived from the oxidation process of vacuum bottom Bitumen production feedstock. It is a result of the distillation tower residue in vacuum oil refineries, with specific penetration points between 85/100.

Penetration and Softening Point

The penetration grade bitumens, including , are specified by the penetration and softening point test. This grade exhibits a thermoplastic property, softening at high temperatures and hardening at lower temperatures. This unique characteristic influences Bitumen 85/100 performance parameters such as adhesion, rheology, durability, and application temperatures.

Thermoplastic Property

Bitumen 85/100 showcases a semi-hard penetration grade suitable for road construction and repair. Its thermoplastic nature makes it ideal for use in hot mix asphalt production, bases, and wearing courses.

Applications of Bitumen 85/100

It is extensively used in road construction, asphalt pavements, hot mix asphalt production, spaying, and chip application. Its relatively low air blowing and penetration properties make it suitable for cold weather areas, ensuring resistance to cracking and optimal performance in varied conditions.

Technical Specifications

The hardness is determined by penetration tests, measuring the depth to which a standard loaded needle vertically penetrates the sample. Bitumen 85/100 temperature-vs-stiffness relationship is influenced by crude oil type and refining methods, ensuring compliance with industry standards like ASTM.

Usage and Benefits

The main usage lies in road construction, asphalt pavements, and hot mix asphalt production. Its versatility extends to cold weather regions, where it maintains structural integrity and prevents cracking, ensuring long-term durability and safety.

Quality Assurance

CARBOKIM Company guarantees the quality of Bitumen Penetration Grade 85/100 through international inspection, quality control, and compliance with ASTM standards. Rigorous testing and batch reports ensure consistent quality and performance in various applications.
