Bitumen 200/300

Bitumen 200/300 is a standard grade of bitumen that is commonly used for road construction and producing high-quality asphalt pavements. This type of bitumen has excellent properties and is primarily used in the production of hot mix asphalt for bases and wearing courses. The quality of Bitumen 200/300 is determined by the penetration and softening point tests. It is specified by the penetration range only. Bitumen 200/300 is thermoplastic, which means that it softens at high temperatures and hardens at lower temperatures. This unique temperature-viscosity relationship is important in determining its performance parameters like adhesion, rheology, durability, and application temperatures. The mode of Bitumen 200/300 varies based on the temperature. The stiffness-temperature relationship of bitumen is determined by the type of crude oil and its refining method. Bitumen penetration grade 200/300 is semi-hard and is suitable for road construction and repair. It is also used for the production of asphalt pavements with specific technical specifications. Bitumen 200/300 is the basic material for all other bituminous products. The hardness of bitumen is determined by measuring the depth to which a standard loaded needle will vertically penetrate in 5 seconds in a sample of bitumen maintained at a temperature of 25 degrees Celsius. In general, Bitumen 200/300 is used in road construction and to produce high-quality asphalt pavements. Its unique properties make it an ideal material for hot mix asphalt for bases and wearing courses.
