Different classification

According to the composition of the environment, oxidized asphalt natural asphalt can be divided into asphalt, lake asphalt, bottom asphalt, etc. D. Asphalt usually occurs in rock cracks or in a mixture with the ground. Asphalt is a natural bitumen that continuously falls from the earth's crust and occurs by long-term transpiration and condensation in rocks and in cracks between rocks. Lake asphalt is a kind of natural accumulation asphalt, which is composed of clay and water in the form of emulsion, mainly in the form of lake surface.

Petroleum asphalt can be roughly divided into straight-run asphalt, solvent-degreased asphalt, oxidized asphalt, mixed asphalt, emulsified asphalt, and modified asphalt according to the production method. d.; From the appearance, it can be roughly divided into liquid asphalt, solid asphalt, diluent, emulsion, modified body, etc. d.; According to the use, it can be divided into travel asphalt, construction asphalt, oxidized asphalt waterproof and moisture-proof asphalt, various special asphalts, named use or function.

Use the difference

Natural asphalt is mainly used to modify or harmonize high-grade bridge deck asphalt, as a drilling aid or to prepare special high-softening asphalt. As a green, low-carbon and environmentally friendly new material, natural asphalt will be widely implemented at all levels of highway construction.

Petroleum asphalt is mainly used as materials, materials and fuels for capital construction, such as transportation (road, railway, aviation), construction, agriculture, water conservancy, industry (extractive industry, manufacturing), civil use, etc.

difference in meaning

Natural bitumen is formed in nature through the long-term kneading of the earth's crust and the gradual modification of the contact between air and water. Natural asphalt exists in a natural way, often mixed with a certain proportion of minerals. According to the composition of the environment, it can be divided into asphalt, lake asphalt, submarine asphalt, etc.

Petroleum bitumen is the product of crude oil processing process. It is mucus, semi-solid substance or solid at constant temperature. It mainly contains alkyl and nepalyl derivatives. It is soluble in trichloroethylene. If you have any other questions, please contact us for oxidized asphalt details or contact us directly.
