Penetration bitumen is semi hard black material known as petroleum grade bitumen which is produced by blowing hot air into the vacuum bottom.
Bitumen penetration grade is suitable for road surfacing, production of asphalt pavements and hot mix asphalt. Low penetration grade bitumen is used in the warm areas while high penetration grade is used in cold areas.
We have the capability to supply customers a wide range of Bitumen penetration grades such as 60/70, 80/100, 85/100, 40/50, 30/40.
