Classification and Uses of Asphalt Powder

Bitumen powder is a finely powdered substance made by grinding and sieving high-temperature asphalt. Below are some detailed information about bitumen powder: One, composition and source.

Bitumen powder, also known as high-temperature powder, is primarily composed of high-temperature asphalt, and may also contain mineral fillers or other chemical additives. Bitumen powder can originate from petroleum asphalt and natural asphalt, among others.

II. Features

The particle size of asphalt powder is typically very fine, commonly processed into sizes ranging from 0-1mm, 0-2mm, 0-3mm, 80-100 mesh, 150 mesh, and 200 mesh. The specific particle size depends on its application requirements. The particle size of the powder is usually between 0.1 to 100 micrometers.

‌Color: Asphalt powder is black or brown-red (colors may vary depending on custom specifications)

High Viscosity: Asphalt powder has a high viscosity, which varies with temperature. Generally, as the temperature rises, the viscosity decreases.

Waterproof and Moisture-Proof: The main component of asphalt powder boasts excellent waterproof and moisture-proof properties, suitable for the production of waterproof materials.

Corrosion Resistance: Asphalt powder exhibits excellent corrosion resistance and is suitable for anti-corrosion materials.

‌Hot Stability: Asphalt powder exhibits good stability under high temperatures, with minimal changes in its physical and chemical properties with temperature variations.

‌Oily: Asphalt powder possesses an oily nature, allowing it to dissolve with other organic substances.

Flammability: Bituminous powder has some flammability, but burns slower in the air.

Toxicity: Certain components in asphalt powder, such as anthracene, phenanthrene, and pyrene, are toxic and pose certain hazards to both human health and the environment. Therefore, proper handling and storage are required.

Use

Road Construction: Asphalt powder can be used as part of asphalt concrete for paving the surface layer of roads and bridges, enhancing the durability and waterproofing capabilities of the roads.

‌Construction: Asphalt powder can serve as a waterproofing material in construction projects such as roof waterproofing and damp-proofing of basements. It can also be mixed with polymers or rubbers to create waterproof coatings or membranes, which are used for waterproofing roofs, basements, swimming pools, and other structures.

‌Refractory Materials: Asphalt powder can be mixed with other materials to produce refractory materials, such as blast furnace mud, blast furnace tamping material, magnesia-carbon bricks, and more.

‌Anticorrosive Materials: Asphalt powder can be mixed with other materials to form anticorrosive coatings, used for the protective coating of metal pipelines, bridges, storage tanks, and more.

Sealant Materials: Asphalt powder can be used to manufacture sealants.
