Our Bitumen Products, Types & Grades

Bitumen - A Versatile Construction Material

Bitumen is a multifunctional petroleum derivative used in various fields such as mobility, construction and industry. In the mobility sector, it binds the aggregates in road construction, ensuring durable and smooth surfaces. In the construction sector, bitumen is of central importance for sealing and waterproofing roofs and provides protection against environmental elements. In the industrial sector, it is used for soundproofing, insulation and as an adhesive. At Nextpetrol, we focus on bitumen products optimized for road construction.

Types and Grades

There are numerous international standards that define the different types and grades of bitumen. These types and grades are classified according to various criteria, which can vary depending on the application and region of the world. Nextpetrol's product portfolio is based on the markets we serve, in particular European and American standards.

Penetration Grade Bitumen

Bitumen is classified by its penetration value, which indicates how far a standardized needle can penetrate a bitumen sample at room temperature. The higher the penetration value, the softer the bitumen.

Viscosity Grade Bitumen

Bitumen is classified based on its viscosity at defined high temperatures. This classification is often used for applications where precise control of flow properties is required.

Modified Bitumen

Modified bitumen is altered by adding petrochemical polymers or other additives to enhance its performance characteristics. This can improve elasticity, adhesion, and resistance to aging, often in response to issues like rutting and cracking due to environmental and stress conditions.

Emulsion Bitumen

Emulsion bitumen is a mixture of bitumen and water created through emulsification. It is commonly used for road construction applications because it is liquid at ambient temperature. It can be processed without prior heating, making it easy to handle and apply. As it hardens, the water evaporates, and the asphalt regains its usual strength. These types and grades of bitumen are classified based on various criteria, which can vary depending on the application and region of the world. There are numerous international standards that regulate the different types and grades of bitumen.

Cutback Bitumen

Cutback bitumen is a variant where bitumen is liquefied by dilution with a solvent such as kerosene, diesel, or gasoline. This process reduces the viscosity of the bitumen, facilitating easier handling and application. After the solvent evaporates, the bitumen returns to its original consistency. Cutback bitumen is often used in various road construction and repair applications.
