Where does bitumen come from?

Bitumen, dense, highly viscous, petroleum-based hydrocarbon that is found in deposits such as oil sands and pitch lakes (natural bitumen) or is obtained as a residue of the distillation of crude oil (refined bitumen).

Bitumen has a melting point of around 240 degrees Fahrenheit which is high enough to be safely used for roadway designs and low enough to be heated up without using a large amount of energy. Karen Abtin Spadana company can supply every grade of bitumen that comes from Iran originally which has the best quality and also best price in the market of Iran.

What is the meaning of 60 70 Bitumen?

Bitumen penetration grade 60/70 means the penetration value is in the range 60 to 70 at standard test conditions which commonly used as a Paving Grade. Bitumen is applicable for the production of hot mix asphalt for bases and pavements and for road construction.

What is difference between bitumen and asphalt?

Bitumen is the liquid binder that holds asphalt together. A bitumen-sealed surface is a layer of bitumen sprayed and then covered with an aggregate. … Asphalt is produced in a plant that heats, dries and mixes aggregate, bitumen and sand into a composite. It’s all good to understand the difference between the two.

What is bitumen used for?

Most refined bitumen is used in the construction industry. Mainly, it serves its use in paving and roofing applications. 85% of all bitumen is used as a binder in asphalt for roads, runways, parking lots, and foot paths
