Bitumen Penetration Grade
ASTM Standard – Bitumen 120/150
Bitumen Grade 120/150, a versatile and essential construction material, serves as the backbone of modern infrastructure. Among the array of bitumen grades, Bitumen 120/150 stands out for its distinct properties and wide-ranging applications.
Bitumen Penetration Grade 120/150 is classified based on its penetration and viscosity properties, with the numbers representing the penetration depth in tenths of a millimetre at a standard temperature of 25°C.
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.
Application
The primary application of Bitumen 120/150 lies in road construction, where it serves as a binding agent in asphalt mixes. Its robust properties contribute to the creation of durable road surfaces capable of withstanding heavy traffic loads and environmental challenges.
Beyond road construction, Bitumen 120/150 finds utility in the industrial sector, where it is employed in the formulation of coatings, adhesives, and sealants, catering to a wide range of applications.
