Bitumen is typically obtained from crude oil through a process called fractional distillation. During fractional distillation, crude oil is heated and separated into different fractions based on their boiling points. The lighter components with lower boiling points, such as gasodiesel, vaporize and are collected at different stages of the distillation process. The remaining fraction, which is the heavier and higher boiling point component, is bitumen.
We can provide you with all kinds of bitumen in standard grades:
Bitumen VG-10
VG-10 is widely used in spraying applications such as surface-dressing and paving in very cold climate in lieu of old 80/100 Penetration grade. It is also used to manufacture Bitumen Emulsion and Modified Bitumen products.
Bitumen VG-20
VG-20 is used for paving in cold climate & high altitude regions.
Bitumen VG-30
VG-30 is primarily used to construct extra heavy duty Bitumen pavements that need to endure substantial traffic loads. It can be used in lieu of 60/70 Penetration grade.
Bitumen VG-40
VG-40 is used in highly stressed areas such as intersections, near toll booths and truck parking lots in lieu of old 30/40 Penetration grade. Due to its higher viscosity, stiffer Bitumen mixes can be produced to improve resistance to shoving and other problems associated with higher temperature and heavy traffic loads.
Bitumen Penetration Grade 40-50
Penetration Grade Bitumen is specified by the penetration and softening point test. Designation 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
Bitumen Penetration Grade 80-100
Bitumen Penetration Grade 85-100
Bitumen Penetration Grade 100-120
