Bitumen Penetration Grade
ASTM Standard – Bitumen 70/100
Penetration Graded Bitumen 70/100 is high-quality asphalt, derived from crude petroleum refining. It is dark in colour and possesses waterproofing and adhesive properties. It is substantially non-volatile and softens gradually when heated. paving grade bitumen for hot asphalt-concrete mixtures. Bitumen 70/100 is applied for construction and reconstruction of roads, highways and other asphalt-concrete pavements.
Cutback RC 250
Rapid Curing 250 RC250 a combination of penetration grade asphalt cement and a diluent or cutter highly rapid in its volatility making it easier to apply.
Cutback MC 800
Rapid Curing 800 MC800 a combination of penetration grade asphalt cement and a diluent or cutter highly rapid in its volatility making it easier to apply.
Uses
Bitumen 70/100 is commonly used to produce hot mix asphalt for the base and wearing courses. a thinner pavement design Usage: The main common usage of bitumen 70/100 is being used in the manufacturing of hot mix asphalt for the base and wearing courses. Due to its high level of viscosity, it enables a thinner pavement engineering design and an overall 30 percent reduction in the amount of asphalt being applied. Bitumen 70/100 is soft type paving grade bitumen and can be used in a wearing course, even in low temperature areas. It can be used in AC and SMA mixes in case the mix is resistant to rutting.
