Bitumen asphalt 60/70 80/100 50/70 grade

タイトルまたは説明

Asphalt, also known as bitumen, is a sticky, black, highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product

Bitumen is known for its waterproofing and adhesive properties, and is created through the crude oil distillation process. The process removes lighter crude oil materials such as diesel and gasoline, and leaves the heavier bitumen behind

 

Penetration Grade Bitumen is a standard bitumen commonly used as a Paving Grade Bitumen in road surfacing, essential for road construction and for the production of asphalt pavements with superior properties, and it's very important once it bounds the aggregates and creates a unique cohesion and stability to the bituminous mix.

All Penetration Grade Bitumen is manufactured from fractional / vacuum distillation of crude oil produced from vacuum residue (short residue) feedstock. Penetration Grade bitumen are specified by the penetration and softening point test.
