Bitumen 40/50 Penetration Grade 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.
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 40/50 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 40/50 is one of the most used bitumen grades and it’s a basic material for all other bituminous products.
Bitumen 40/50 is commonly declared under HS Code 27132000, which is designated for petroleum bitumen and other residues from petroleum oils.
Bitumen Penetraton is classified under the international Harmonized System (HS) used for customs and trade documentation worldwide. The Bitumen grade 40/50 HS Code provides a standardized numerical method to identify products, ensuring uniformity in global trade.
Bitumen Pentration 40/50 is suitable for road construction and for the asphalt pavements with superior properties. This type of bitumen used in the manufacture of hot mix asphalt for bases and wearing courses and the main usage of this product is used in the road at tropical regions. the bitumen is provided during the presses of oxidation of vacuum bottom in bitumen production units. Due to its high air blowing and penetration, it is used in tropical areas with the Warm weather. It is not softened at high temperature and does not fail its qualities.
RABIT (RAHA BITUMEN) Company guaranty the quality of bitumen penetration grade 40/50 with the arrangement of the international inspector to check quality and quantity of the bitumen penetration grade 40/50 during the loading to the vessel and controlling the production by QC by batch test report before shipping. RABIT Company guarantees the quality to meet with ASTM.
There are several different ways to package the bitumen which can vary depending on the tonnage, type, and grade of the bitumen- as mentioned before, different grades of bitumen have different levels of stiffness and viscosity- so the grade also plays an important role in choosing a suitable packaging.
Bitumen grade 40/50 is commonly packed in new steel drums, 150, 180 & 220 Kg barrels and Jumbo Bags or 300 Kg Bitubag.
Density is a core physical characteristic that expresses how much mass is contained in a given volume of a material. For bitumen, this property is especially important because it influences how the material behaves and performs in different uses. Density is usually reported in kilograms per cubic metre (kg/m³) or grams per cubic centimetre (g/cm³). For the widely used penetration grade bitumen 40/50, the density typically falls between about 1,000 and 1,050 kg/m³.
