Classification of asphalt materials

The first category is ground asphalt, mainly natural asphalt and petroleum asphalt; The second category is tar pitch, mainly coal pitch, shale pitch, peat pitch and wood tar. There are two types of refining of natural bitumen, one is direct mining, such as the bitumen of the Trinidad and Tobago Bitumen Lake; the second is obtained by refining in sandstone and sand. Petroleum asphalt is made from the processing of petroleum products, petroleum asphalt can be categorized according to the following system : According to the production method is divided into: straight-run asphalt, solvent de-oiled asphalt, oxidized asphalt, blended asphalt, emulsified asphalt, modified asphalt and so on; According to the appearance of the form is divided into: liquid asphalt, solid asphalt, diluent, emulsion, modified body, etc.; According to the use of: road asphalt, construction asphalt, waterproof and moisture-proof asphalt, to the use or function of the name of a variety of special asphalt.
