ABOUT BITUMEN
Bitumen, also known as asphalt, is a black, sticky, and highly viscous liquid or semi-solid form of petroleum. It is primarily used in the construction industry for paving roads, waterproofing roofs and as a binding agent in concrete. Bitumen is also used in the production of various other products such as adhesives, sealants, and coatings. It is a valuable resource and is found in many parts of the world, including Canada, the United States, and the Middle East.
BITUMEN TYPES
There are several types of bitumen available, each with its own characteristics and applications. Here are some commonly used types:
Penetration Grade Bitumen: This type is classified based on its penetration value, which measures the hardness of the bitumen. It is commonly used in road construction and has different grades, such as 40/50, 60/70, and 80/100.
Polymer Modified Bitumen (PMB): PMB is a blend of bitumen and polymer additives. It offers improved performance in terms of elasticity, durability, and resistance to deformation. PMB is often used for high-stress applications like airports and racetracks.
Cutback Bitumen: Cutback bitumen is a mixture of bitumen and a solvent such as gasoline or kerosene. It is used for spraying applications like prime coats, tack coats, and surface dressings. The solvent evaporates, leaving behind a bitumen film.
Emulsion Bitumen: Emulsion bitumen is a suspension of bitumen droplets in water, stabilized with an emulsifying agent. It is commonly used for surface treatments, such as chip seal and slurry seal, as well as in cold mix applications.
Oxidized Bitumen: This type of bitumen is produced by blowing air through hot bitumen, resulting in increased hardness and higher softening point. It is used primarily for industrial purposes like roofing, pipe coating, and electrical insulation.
These are just a few examples of the various types of bitumen available in the market, each catering to specific applications and requirements.
