Since the emulsified asphalt itself is a meta-stable system, in order to ensure that the quality of the emulsified asphalt remains stable during use, the storage of the emulsified asphalt should be as follows:

Storage condition requirements

(1) Different types of emulsified asphalt cannot be mixed, and must be stored in separate categories.

(2) Emulsified bitumen should be stored in shade to avoid direct sunlight.

(3) The emulsified bitumen should be kept tightly closed to prevent the evaporation of water or the mixing of other substances such as rain from affecting the quality of the emulsified bitumen.

(4) High temperature or low temperature storage should be avoided for emulsified asphalt, usually 5~50 C.

(5) Long-term storage of emulsified asphalt must be regularly stirred to make it uniform. Special attention should be paid to stirring it before use to ensure the uniformity of the emulsified asphalt. The mixing time is determined by the amount of emulsified asphalt stored, usually 15-20 minutes.

(6) The storage time of emulsified asphalt should not be longer than 1 month, and it is usually best to use up within 3-5 days.

Storage tank, agitator, emulsified asphalt pump and other hardware requirements

(1) The emulsified asphalt storage tank needs to be equipped with a stirrer. The mixing of the emulsified asphalt storage tank is a low-speed large blade, and the rotation speed is 60~80 rpm.

(2) Emulsified asphalt pump: usually centrifugal pumps, screw pumps, diaphragm pumps, etc. are used to pump the emulsified asphalt with less shear. Gear pumps are opposed.

(3) The storage tank is equipped with heating coils, and the special emulsified asphalt needs to be used at a relatively high temperature.
