bitumen
about bitumen
Bitumen is a black, sticky, and highly viscous material derived from crude oil or found naturally in deposits. Known for its waterproofing, adhesive, and durable properties, bitumen is one of the most widely used materials in construction. From paving smooth roads to providing long-lasting waterproofing solutions, it plays a vital role in modern infrastructure.
types of bitumen
- Natural Bitumen: Found in natural deposits, used in specialty applications.
- Petroleum Bitumen: Produced during crude oil refining, mainly used in road construction.
- Blown/oxidized Bitumen: Manufactured by blowing air through hot bitumen; ideal for roofing, waterproofing, and industrial uses.
- Cutback Bitumen: Bitumen blended with solvents for easier application in cold conditions.
- Emulsion Bitumen: Water-based form, eco-friendly and suitable for wet conditions.
- Polymer Modified Bitumen (PMB): Enhanced with polymers for improved elasticity, durability, and performance in extreme weather.
- Graded Bitumen: Classified by penetration, viscosity, or performance to match specific construction requirements.
