Properties

Bitumen 85/100, often referred to as paving grade bitumen, is a type of bitumen that falls within a specific viscosity range. The numbers 85 and 100 represent the penetration grade, which measures the consistency of the bitumen. A higher penetration value indicates softer bitumen, making bitumen 85/100 relatively softer than some other grades. This specific grade is well-suited for various construction purposes due to its balance between stiffness and flexibility.

Applications

Road Construction

One of the primary applications of bitumen 85/100 is in road construction and maintenance. It is commonly used as a binder in asphalt mixtures, where it provides adhesive properties, durability, and resistance to deformation under heavy traffic loads and varying weather conditions. The flexibility of bitumen 85/100 allows it to accommodate the movement of the underlying layers, preventing cracks and enhancing the lifespan of roads.

Waterproofing

Furthermore, bitumen 85/100 finds use in the roofing industry. Its waterproofing capabilities make it an ideal material for manufacturing roofing sheets, shingles, and membranes. Bitumen’s ability to form a seamless, watertight layer helps protect buildings from water infiltration, thus contributing to their longevity.

Production process

The production of bitumen 85/100 involves the refining of crude oil. During this process, bitumen is separated from other components of crude oil through fractional distillation. The resulting bitumen is then further processed to achieve the desired penetration grade and other properties. The availability of bitumen 85/100 depends on the quality of the crude oil and the refining techniques employed.

Environmental effects

While bitumen 85/100 offers numerous benefits, its production and use raise environmental considerations. The extraction and processing of crude oil to obtain bitumen contribute to carbon emissions and other environmental impacts. However, the industry is actively researching and implementing more sustainable practices, such as incorporating recycled materials into bitumen mixtures and exploring alternative binders with lower environmental footprints.

Conclusion

In conclusion, bitumen 85/100 plays a vital role in modern construction, particularly in road paving and waterproofing applications. Its unique balance of stiffness and flexibility, along with its adhesive properties, make it a valuable construction material. Despite its environmental challenges, ongoing efforts to improve sustainability within the industry highlight the importance of responsible bitumen production and usage. As construction practices continue to evolve, bitumen 85/100 will likely remain a key component in building resilient infrastructure for the future.
