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.
Petroleum asphalt grade: No. 50, No. 70, No. 90, No. 110
Heating temperature of asphalt: 160~170, 155~165, 150~160, 145~155
When in production, the asphalt should be continuously heated and cannot be cooled. When not in production, it can be cooled.
Asphalt of different grades should never be mixed. Different grades of asphalt have different prices, different properties, different levels of road surface, and so on.
