How is asphalt properly stored after it is refined?

If it is a barrel (50Kg-200Kg), it can be stored directly, there is no special requirements, but in the production of barrels, into the special insulation of asphalt tanks; if it is a tanker, it should be pumped directly into the insulation of asphalt tanks. Insulated tanks have different specifications such as 50 tons, 60 tons, the number and capacity can be decided according to the site, the amount of production, the amount of money and other factors.

Asphalt Production Methods

distillation method: is the regular pressure distillation of crude oil from gasoline, kerosene, diesel and other light fractions, and then by decompression distillation (residual pressure of 10 ~ 100mmHg) out of the decompression distillate oil, the remaining residue in line with the specifications of road asphalt can be produced directly out of the asphalt products, the resulting asphalt is also known as straight-run asphalt, the production of road asphalt is the main method of asphalt.

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.

How many hours can you leave asphalt material

The amount of time an asphalt mixture is left in place is affected by a number of factors, including temperature, humidity, oxygen concentration, and mixture composition. Generally, it is recommended that asphalt mixtures be used within 3 hours to ensure optimum performance. If it takes longer than 24 hours, the effectiveness of the mix may be compromised. For ordinary asphalt mixtures, the storage time should not exceed 72 hours. For modified asphalt mixtures, the storage time should not exceed 24 hours, and it is recommended that they be used on the same day only. Therefore, the placement time of asphalt mixtures should be determined according to the specific type and environmental conditions in order to ensure the performance of the mixture
