Classification and Uses of Asphalt Powder

Bitumen powder is a fine powder substance produced by grinding and sieving high-temperature asphalt. Here are some details about bitumen powder: One, composition and origin.

Bituminous powder, also known as high-temperature asphaltCoal, asphaltPowder, mainly composed of high-temperature asphalt, may also contain some mineral fillers or other chemical additives. Asphalt powder can originate fromCoal Tar PitchPetroleum asphalt and natural asphalt, etc.

II. Features

The particle size of asphalt powder is typically very fine, usually 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 size of the powder particles usually ranges between 0.1 to 100 micrometers.

‌Color: Bitumen powder is black or brown-red (colors may vary due to customized specifications)

High Viscosity: Asphalt powder has a high viscosity, which varies with temperature; generally, as the temperature increases, the viscosity decreases.

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

Corrosion Resistance: Asphalt powder boasts excellent corrosion resistance, suitable for use in anticorrosive materials.

‌Thermal Stability: Asphalt powder maintains good stability at high temperatures, with minimal changes in its physical and chemical properties with temperature variations.

‌Oily: Asphalt powder possesses a certain degree of oiliness, allowing it to be soluble with other organic substances.

Flammability: Bitumen powder has a certain flammability, but it 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 humans and the environment. Therefore, proper handling and storage are required.

III. Usage

Road Construction: Asphalt powder can be integrated into asphalt concrete as a surface layer for road and bridge paving, enhancing the durability and waterproofing capabilities of the road.

‌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 rolls, 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 slag, blast furnace ramming mass, and magnesite-carbon bricks, etc.

Corrosion Materials: Asphalt powder can be mixed with other materials to create corrosion-resistant coatings, used for the protective coating of metal pipelines, bridges, storage tanks, and more.

Sealant Materials: Asphalt powder can be used in the production of sealant materials.
