Bitumen 30-40

Bitumen 30-40

 

Bitumen 30-40 is a thermoplastic material and its stiffness is dependent on temperature. The temperature-vs-stiffness relationship of bitumen is dependent on the source of crude oil and the method of refining. Bitumen penetration grade30/40 is semi hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements with below technical specification. This grade of bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.Bitumen 30/40 is most used bitumen grade and basic material for all other bitumenious products.
