bitumen is produced from petroleum and primarily used for the production of asphalt. Its consistency depends largely on temperature — at hot temperatures it is viscous and larger chemical compounds such as aliphatics, petroleum resins, and asphaltenes move freely in the mass. Since asphalt and oxidized bitumen 110/30 are used for road construction as well as for waterproofing work, the longest possible product lifetime is desirable To slow down the aging of the material, reactions triggered by reactive gases, light, and heat must be minimized.
Application of bitumen 110-30
Bitumen is widely used as an anti-slip layer compound in the piling industry, for the manufacture of roofing felts, for sound dampening felts and under carriage sealant in the automobile industry, electric cable joint protection, joint filling compound, sealant compound and many others. The vast majority of bitumen is used by the construction industry, as a constituent of products used in paving and roofing. Excellent waterproofing characteristics and thermoplastic behaviour make it ideal for a wide range of applications. At elevated temperatures (typically between 100 and 2008C) it acts like a viscous liquid, and can be mixed with other components and manipulated and formed as required. Once Bitumen 110/30 cooled, it is an inert solid that is durable and hydrophobic (repels water).

Once cooled, it is an inert solid that is durable and hydrophobic (repels water).
Asphalt contents
The bitumen content of an asphalt is one of its most important characteristics. Using a oxidized bitumen 110/30 content lower than required may result in a dry, stiff mixture that is difficult to place and compact and will be prone to cracking and other durability problems while possessing lower resistance to fatigue cracking. Too much bitumen is likely to make the asphalt uneconomic because of the relatively high cost of bitumen and, in performance terms, it is likely to make the asphalt prone to bleeding and deformation.Asphalt content of bitumen 110-30 is depend on process of production line.if heat too much it may convert to coke.
