Bitumen is an oil based engineering material, produced to meet a variety of end-use specifications based on physical properties. Due to its properties Bitumen is a crucial component of road construction and maintenance materials, which contributes to create significant flexibility, weather resistance and durability of the surface material.
Bitumen are situable for use in the construction and maintenanse of roads, airfields and other paved areas.
