PENETRATION GRADE BITUMEN *0/*0
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.
USAGE:
Asphalt bitumen used in expansion joint construction is composed of a blend of asphalts, vegetable fibers, and mineral fillers formed under heat and pressure between two asphalt-saturated liners. It is waterproof, permanent, flexible, and self-sealing. It can fully absorb the bridge deck\'s vibration shock which come from vehicular traffic,and is effective in reducing the bridge cracks.
