Asphalt tank:
1. Asphalt tank should have good thermal insulation performance, and the asphalt temperature drop value every 24 hours should not exceed 5% of the difference between asphalt temperature and ambient temperature.
2. 500t asphalt tank should have sufficient heating area to ensure that the asphalt with short-circuit capacity can continue to provide asphalt above 100℃ after heating for 24 hours at an ambient temperature of 25℃.
3. Partial heating tank (tank in tank) should not have significant deformation after bearing pressure effect.

Asphalt heating tank:
1. Asphalt high-temperature heating tank should have good thermal insulation performance, and the asphalt temperature drop value every hour should not exceed 1% of the difference between asphalt temperature and ambient temperature.
2. The asphalt in the short-circuit capacity heating tank within 50t should be able to be heated from 120℃ to above 160℃ within 3h, and the heating temperature can be adjusted at will.
3. Partial heating tank (tank in tank) should not have significant deformation after bearing pressure effect.
