Many users who use emulsified asphalt do not understand why emulsified asphalt needs to be demulsified, nor what its use is. Therefore, the editor of emulsified asphalt manufacturer Sinoroader would like to take this opportunity to explain in detail the relevant knowledge of emulsified asphalt demulsification.

Usually asphalt needs to be heated to increase the temperature before it can be melted, so it needs to be constructed at high temperature. However, later, people emulsified the asphalt used at high temperature through mechanical stirring and chemical stabilization, spreading the asphalt to the tax and liquefying it into a very viscous form at room temperature. Low and very free flowing road construction material, emulsified bitumen.
Since emulsified asphalt is used at room temperature, the moisture contained in it needs to volatilize before it can condense into a whole with the material. The basis for simply determining whether the moisture exists is to see whether its emulsified state still exists, that is to say, whether its emulsified state still exists. If it is not damaged, it means the emulsion is broken. As long as the emulsification is broken, it means that there is no moisture in the asphalt.
The length of the demulsification time needs to be determined based on the actual usage. However, if the demulsification time is too fast, it may be caused by too high emulsifier activity or too high water temperature. You need to promptly adjust the amount of emulsified asphalt emulsifier and pay attention to the water temperature. If the emulsification time is too long and the emulsification does not break after several hours, you need to consider whether the emulsifier activity and the asphalt content are too low.
The above is the knowledge about emulsified asphalt demulsification explained to you by Sinoroader, an emulsified asphalt manufacturer. I hope it can be helpful to you.
