Bitumen VG 30:

Bitumen VG 30   is a standard grade Bitumen usually we use as a Paving Grade Bitumen. It is suitable for road construction and for the production of asphalt pavements with superior properties. Also This grade of Bitumen mainly can use in the manufacture of hot mix asphalt for bases. How ever wearing courses, and possesses characteristics and qualities unique sand quite different from other agents.
They achieve very flexible and tenacious connections with other materials due mainly to viscoelastic response of bitumen.  Which behavior depends on how fast charges we apply. Also Pars Universal Bitumen Supply Viscosity Grade Bitumen and petroleum grade bitumen. Manufacture from fractional / vacuum distillation of crude oil, which practical appliance and behavior varies according to its temperature.

Providing Bitumen VG 30:

Pub-ltd produce Bitumen from vacuum residue (short residue) feed stock. Viscosity Grade bitumens specify by the methods described in ASTM Standard D3381-09 and AASHTO M226-80 (2008). Also Viscosity Grade specifications covers bitumen (asphalt) graded by Viscosity at 60 C (140 °F). There are two methods of grading:ºStandard Viscosity Grade Bitumen (AC-Grades), in which the Viscosity of the standard bitumen (asphalt) measure at 60 ºC (140 ºF). Also RTFOT Viscosity Grade Bitumen (AR-Grades), in which the Viscosity of bitumen (asphalt) is measured at 60 °C (140 °F) after the roll on thin film oven test.
