Kenyan Bitumen Asphalt Suppliers and Manufacturers

Bitumen penetration grade 40/50 bitumen means the penetration value is in the range 40 to 50 at standard test conditions which commonly used as a Paving Grade. Bitumen is applicable for the production of hot mix asphalt for bases and pavements and for road construction. Penetration Grade Bitumen supplied by RABIT (RAHA BITUMEN) Co. This bitumen is produced through aeration on vacuum bottom (the raw material used for making bitumen left in vacuum distillation column in oil refineries) in bitumen production units. Its penetration grade ( the measure of bitumen hardness) is between 40 to 50. Bitumen is specified by the penetration and softening point test. Designing is by penetration range only. The penetration grade bitumen has 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.

Bitumen penetration grade 60/70 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 60/70 is the most used bitumen grade and basic material for all alternative bituminous products. Bitumen Penetration Grade 60/70 is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Penetration Grade Bitumen supplied by RAHA GROUP is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. The Bitumen supplied by RAHA GROUP is produced from vacuum residue (short residue) feedstock. RAHA 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.

Bitumen Penetration Grade 85/100 is a standard penetration grade Bitumen usually used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties. This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. This bitumen is produced through aeration on vacuum bottom (the raw material used for making bitumen left in vacuum distillation column in oil refineries) in bitumen production units. Its penetration grade ( the measure of bitumen hardness) is between 85 to 100. 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 Bitumen mode is dependent on temperature. The temperature-vs-stiffness relationship of bitumen is dependent on the type of crude oil and its refining method. Bitumen penetration grade 85/100 is semi hard penetration grade bitumen used as a paving grade bitumen which is suitable for road construction and repair. It is also used for the production of asphalt pavements with the below technical specification. This grade of bitumen is mainly used in the manufacturing of hot mix asphalt for bases and wearing courses. Bitumen 85/100 is one of the most used bitumen grades and a basic material for all other bituminous products. Penetration determines the hardness of bitumen by measuring the depth to which a standard loaded the needle will vertically penetrate in 5 seconds, in a sample of bitumen maintained at a temperature of 25 degrees Celsius.

VG10 bitumen is the softest grade of viscosity bitumen. This type of bitumen is widely used for spraying applications and surface coating. VG 10 bitumen means that your bitumen is also suitable for paving roads in a very cold climate instead of the old 80/100 penetration grade. The air temperature that matches VG10 bitumen ranges from -10 �¢?�¦C to 25 �¢?�¦C. Due to the high temperatures in hot climatic zones, the application of VG10 cannot provide desirable rutting resistance. This type of bitumen is also used to manufacture bitumen emulsions and modified bitumen products especially in India. As a viscosity grade bitumen, VG10 has a better performance incold weather.

VG-20 bitumen is a grade of viscosity bitumen used in cold climatic and high altitude regions. This grade of bitumen is suitable for road construction in regions with 30 to 37 C average temperature. In North India, vg20 is used for road construction in hot mix asphalt. The standard penetration value of bitumen viscosity grade VG-20 is 60 mm at 25 C. The absolute viscosity of VG-20 bitumen is 1600 to 2400 poise at 60 C.

This bitumen is primarily used for the construction of extra-heavy bitumen pavements that have to bear significant traffic loads. Bitumen VG30 is the most widely used type of bitumen in road construction, insulation, building construction industries, and also in the production of cutback bitumen. it is better to know that this vg30 bitumen can be used instead of 60/70 penetration bitumen grade.

VG40 bitumen is used in areas in which high pressure comes from heavy traffic loads, such as intersections, near tolls booths, and truck parking lots. Due to the high viscosity of this bitumen, it is more appropriate for improving resistance to shoving and other problems associated with higher temperatures and heavy traffic loads. It's long time that industries use vg-40 instead of the penetration grade bitumen 40/50.
