Bitumen 20/30

Bitumen 20/30 Overview

Bitumen 20/30 is a standard penetration grade bitumen that functions as a paving material for road construction and repairs. Additionally, it serves as a raw material for producing higher-grade paving bitumens. With its thermoplastic properties, it softens at high temperatures and hardens when cooled, This makes it highly adaptable to varying weather conditions, allowing it to perform well in road construction and asphalt pavement production.

Temperature-Stiffness Relationship

The temperature-stiffness relationship of bitumen 20/30 depends on the type of crude oil used and the refining method. As a semi-hard penetration bitumen, it is suitable for paving applications, Therefore, it is one of the most commonly used grades in the industry, especially in hot mix asphalt production for bases and wearing courses. Moreover, bitumen 20/30 is also essential in the manufacturing of other bituminous products.

Softening Point and Penetration

Bitumen 20/30 uses pure petroleum-grade bitumen, produced by passing hot air through vacuum bottom residues of crude oil and removing hydrocarbons. It typically has a penetration range of 20–30 desi-millimeters, along with a softening point between 55°C and 63°C, Furthermore, the thermoplastic behavior of this grade, similar to synthetic resin materials, enables it to soften when heated and harden when cooled. Compared to other grades, it also demonstrates stronger viscosity.

Uses and Applications

Bitumen 20/30 is ideal for road construction and repairs, Additionally, it works effectively in the production of hot mix asphalt for both base and wearing courses. Its superior properties make it an excellent choice for creating long-lasting, durable asphalt pavements.Quality Assurance and Standards
