Bitumen 60 70 , Bitumen VG grade

Descripción del producto

Bitumen penetration grade *0/*0 is semi-hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair conjointly for the production of asphalt pavements with below technical specifications. This grade of bitumen is mainly used in the manufacture of hot combine asphalt for bases and wearing courses. Bitumen *0/*0 is the most used bitumen grade and basic material for all alternative bituminous products.Bitumen Penetration Grade *0/*0 is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Penetration Grade bitumens are specified by the penetration and softening point test. The designation is by penetration range only. The penetration grade bitumens have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/ viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability and application temperatures of bitumen.
 

The penetration grade bitumen is refinery bitumen that is manufactured at different viscosities. The penetration test is carried out to characterize the bitumen, based on the hardness. Thus, it has the name penetration bitumen.

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, and its very important once it bounds the aggregates and creates a unique cohesion and stability to the bituminous mix.

Penetration value is the vertical distance traversed or penetrated by the point of a standard needle into the bituminous material under specific conditions of load, time and temperature.
