Definition of Bitumen Penetration Grade 85/100
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. Penetration Grade Bitumen supplied by RABIT (RAHA BITUMEN) Co. is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. The Bitumen supplied by RABIT Trading 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 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 it’s 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.
Application of Bitumen 85/100
Bitumen 85/100 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 spaying and chip application. The bitumen is provided during the presses of oxidation of vacuum bottom in bitumen production units. Due to its relatively low air blowing and penetration, It is used in areas with cold weather for asphalting and insulation. It is not cracked in low temperatures.
Guaranty and safety
RABIT (RAHA BITUMEN) Company guaranty the quality of bitumen penetration grade 85/100 with the arrangement of the international inspectors to check quality and quantity of the bitumen penetration grade 85/100 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.
Packing
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 85/100 is commonly packed in new steel drums, 150, 180 & 220 Kg barrels and Jumbo Bags or 300 Kg Bitubag.
- 1 MT Jumbo Bag with Steel Cage and Pallet- Loading 20 Jumbo Bag in 20ft Container= 20 Ton- The most common packaging for East of Asia and South America
- 1200 Kg Jumbo Bag- Loading 20 Jumbo Bag in 40ft Container= 24 Ton- The most common packaging for SouthEast of Asia
- 300Kg Bitubag- Loading 80 Bitubag in 20ft Container= 24 Ton- Of course, it is worth noting that containers must be sent to the factory for loading, which is subject to a cost.
- 180kg New Steel Drum- Loading 110Drum in 20ft Container= 19.8-20 Ton- The most common packaging for East of Asia and Africa Countries
- 150kg New Steel Drum- Loading 110Drum in 20ft Container= 16.5 Ton- The most common packaging for Bangladesh, Nepal- Indonesia
- Bitutainer- Loading 25 Ton Bulk Bitumen in Bitutainer- This type of packaging is not common due to the high cost of the Bitutainer and is often suitable for short distances where round-trip transportation is cost-effective.
- Bulk in Tanker Truck= Loading 24-25 Ton Bulk Bitumen in Tanker Truck- Suitable for neighboring countries
- Bulk in Bitumen Carrier (Bulk Vessel): Loading 2,000-40,000 Ton Bitumen in Bulk Vessel- Very convenient and suitable and cost-effective for customers who have tanks at the destination port.
