BITUMEN & OIL PRODUCTS
BITUMIN & OIL PRODUCTS
Bitumen is a sticky, black, highly viscous liquid or semi-solid form of petroleum. it is commonly referred to as asphalt. It may be found in natural deposits or may be a refined product, and is classed as a pitch.
Bitumen is a product of Crude Oil Distillation. It is a semi-solid hydrocarbon product produced by removing lighter fractions (such as liquid petroleum gas, petrol, and diesel) from heavy crude oil during the refining process. As such, it is correctly known as refined bitumen. Petra Oil is a non-stop partner that can source products from refineries around the world and deliver them to clients in remote locations. Our full supply chain includes sourcing, packing, finance, logistics, and customs to the destination of our customers.We deliver and supply bitumen needed to make asphalt and bitumen-based products.
Fertilizers Used in Bitumen
The fertilizer used in bitumen may include MAP, DAP, TSP, NPK, or a combination thereof, and can come in various forms such as granular, crushed, compacted, crystalline, or prilled fertilizer. Prior to emulsification, the bitumen, cutback bitumen, or combination of bitumen and cutback bitumen may comprise 20-100% bitumen.
Types of Bitumen
- Road Bitumen
- Industrial Bitumen
- Modified Bitumen
- Rubber Bitumen
Road Bitumen
Bitumen is the adhesive used for asphalt toppings and bituminous layers of roadway structures, jointing the inorganic components of asphalt (sand, broken stone, ballast, and most frequently limestone dust).
In terms of the elemental composition of bitumen, it is 80-85% carbon, 9-10% hydrogen, and contains various amounts of heteroatoms. The amount of oxygen can vary from 2 to 8%, depending on the origin and production technology, and the sulphur content can range from a few tenths of a percentage to 7%, depending on the origin.
Bitumen is a viscous or viscoelastic material depending on the test temperature. Upon heating, it gradually softens and then becomes liquid. Bitumen with viscoelastic properties over a wide temperature range can be tested by rheological measurements. Rheological characterization allows performance-based classification of bitumen.
Industrial Bitumen
Building bitumen produced by MOL fully satisfies the limit values specified in the test methods of conventional bitumen. Furthermore, it increases the durability of roofing and waterproofing felts made from it and guarantees appropriate resistance against aging.
Modified Bitumen
Modified bitumen products are more durable and are primarily used on roads subjected to high traffic loads. Compared to road bitumen, these types have more flexible qualities and can bear temperature changes on a wider scale.
Rubber Bitumen
In line with the principle of reuse and recycling, MOL and the University of Pannonia (Veszprem) have developed chemically stabilized rubber bitumen as a new type of road construction binder through several years of research and development. Rubber bitumen received a Construction Technical Permit for use in transport construction in 2008 (ÉME 13/2008). The product and the manufacturing process were patented in 2009 (HU 226481).
Test-type road construction and asphalt testing in recent years have demonstrated significantly better quality than normal bitumen and excellent user properties for rubber bitumen, in line with international experience.
