What is modified bitumen?
Modified bitumen has three layers: boards, tar and mineral. It is a type of processed asphalt that has several ways of application.
This product is also suitable for roofs in both hot and cold temperatures. Furthermore, this type of bitumen can expand without losing its shape.
Modified roofs cost approximately $1.50 to $3.00 per square that is a reasonable price.
Roofing with this type of bitumen will be long-lasting with an average life of 20 years. However, it can last even longer with just basic care, since it’s a low-maintenance roofing system. In general, this type of bitumen roofs have a lot of advantages over other types of roofing materials, and are the modern alternative to the built-up roof.
Modified Bitumen application
The use of this type of bitumen has increased in road and building constructions in the world, notably in the Middle East & Africa regions,
due to the modified form of bitumen benefits such as low maintenance cost and efficiency. It is suitable for road constructions
that involve tunnel liners, bridges and flyovers, highways, and airport runways, where the use of high material performances is vital.
The future of modified bitumen
The analysts have estimated that the global this bitumen market value will be about 19.29 Billion USD by 2021, growing at a CAGR of 6.5%. There is a high probability for road constructions to grow at the highest rate during that period.
How do built-up roofing and modified bitumen differ?
A commercial roofing builder will have alternating sheets of roofing felt and bitumen in the form of asphalt, tar, or cold-applied adhesive.
Which type of bitumen should a commercial roofing builder use?
Conclusively, deciding on the actual type of bitumen depends on the type of project.
To lessen the timescales and to avoid the use of open flames, SBS-Modified Bitumen gives roof builders the versatility needed whilst maintaining the same level of hardwearing weather-proofing. Still, because APP bitumen is more suitable for hot-melt conditions, it may be better.
In this article, we discuss the meaning and simple definition of modified bitumen. Moreover, we talked about its applications, approximate price, and demand. To sum up, this product has many functions in roofing, while it has many uses in construction and road projects and coatings. Furthermore, this product is generally similar to asphalt, but has some extra additives. As a final point, providing a high-quality bitumen for the constructions have a high importance.
