Hiwa Oil Co, bitumen penetration grade 120/150 is used mainly as a paving grade, which is suitable for road construction, and maintenance. This grade of bitumen is normally used in the manufacturing of hot mix asphalt for pavement bases and wearing courses. Bitumen 120/150 is one of the other most used bitumen grades.
Penetration bitumen grade 120/150 is produce by process of vacuum Bottom (VB) and air in the reactor. And due to the control of the process conditions, we reaching to pure quality of penetration grade bitumen 120/150 which has a penetration 120 to 150. The penetration grade bitumen 120/150 has a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures.
Guaranty and safety of penetration grade bitumen 120/150
Hiwa Oil Co, guaranty the quality of penetration grade bitumen 120/150, while inspecting by international inspection companies, the both quality and quantity of Penetration Bitumen grade 120/150, at loading port before loading and completing containers stuffing. The penetration Bitumen grade 120/150 also has its own prove of product quality of each batches by QC, while producing in refinery and before shipping. Hiwa Oil Co, guarantees the quality which meet with ASTM, according to following specification.
