Bitumen Penetration Grade 30/40
Description of Bitumen 30/40
Penetration Bitumen Grade 30-40 is Semi-Hard penetration grade bitumen using as Paving Grade Bitumen suitable for road construction and repair also for the production of Asphalt pavements with below Penetration Bitumen 30/40 Specifications. This grade of bitumen mainly used in the manufacture of hot mix Asphalt for bases and wearing courses.
Bitumen Penetration Grade 30/40 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.
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.
Properties of Bitumen 30/40
The bitumen penetration grade 30/40 supplied by RAHA Oil is produced from the vacuum residue (short residue) feedstock. Penetration grade bitumens are specified by the penetration and softening point test. Penetration grade bitumens have a thermoplastic property which causes the material to soften at high temperatures and to harden at low temperatures. The temperature-vs-stiffness relationship of bitumen is dependent on the source of crude oil and the method of refining. Bitumen penetration grade 30/40 is semi-hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements with below technical specifications. This grade of bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.
Uses of Bitumen 30/40
RAHA Bitumen 30/40 is used in specialized applications like airport runways and also in very heavy traffic volume roads in coastal cities in the country.
This grade of bitumen mainly used in the manufacture of hot mix asphalt for bases and wearing courses. suited for areas where the difference in min and max temperature is 25 C.
Guaranty and Safety of Bitumen Penetration 30/40
RAHA Oil Company guaranty the quality of bitumen penetration grade 30/40 with the arrangement of the international inspector to check quality and quantity of the bitumen penetration grade 30/40 during the loading to the vessel and controlling the production by QC by batch test report before shipping. RAHA Oil Company guarantees the quality to meet with ASTM.
Packing of Bitumen 30/40
Paving Bitumen 30/40 is commonly packed in new steel drums, 150, 180 & 220 Kg barrels and 1MT and 500Kg Jumbo Bags or 300kg Bitubag.
Likewise, the rest of the grades are ready to load Ex-work bulk RAHA Bitumen by truck.
