Penetration bitumen

40/50, 50/70, 60/70, 60/90, 80/100, 85/100

Penetration Grade Bitumen is a standard bitumen usually used as a Paving Grade Bitumen essential for road construction and for the production of asphalt pavements with superior properties. The penetration grades bitumen is refinery bitumen which is produced by different viscosity. In fact, Penetration bitumen is semi hard black material known as petroleum grade bitumen. The penetration test is carried out to characterize the bitumen, based on the hardness.

The common bitumen penetration grades are 60/70, 80/100, 85/100, 40/50 and 30/40; which normally Low penetration grade bitumen is used in the warm areas while high penetration grade is used in cold areas. The major Penetration Grade Bitumen is Bitumen 60/70 that is generally used for all the markets.

This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.

Penetration test of Bitumen determines the hardness or softness of bitumen by measuring the depth in millimeter to which a standard loaded needle will penetrate vertically in five seconds while the temperature of the bitumen sample is maintained at 25 C.
