Emulsion bitumen is a new emulsion formed by mechanical action of asphalt and emulsifier aqueous solution.
Emulsion bitumen is classified according to the different particle properties of the bitumen emulsifier used: cationic emulsion bitumen, anionic emulsion bitumen and nonionic emulsion bitumen.
More than 95% of road construction uses cationic emulsion bitumen. Why does cationic emulsion bitumen have such advantages?

Preparation items for micro-surfacing slurry sealing: materials, construction machinery (micro-surfacing paver) and other auxiliary equipment.

Cape seal is a composite highway maintenance construction technology that uses a construction process of first laying a layer of gravel seal and then laying a layer of slurry seal/micro-surfacing. But what should you pay attention to when doing cape sealing? Maybe there are still many people who are not too clear about it. Today we will briefly talk about this issue.

What is needed to produce emulsified asphalt? How to do it?
1: Determine the customer range of emulsified asphalt and which business channels need to be expanded in the future.
2: Where does the technology for the production and application of emulsified asphalt come from? This question is related to: How to choose materials? How to self-check the various indicators of the product? How to determine the emulsifying effect and stability of the product? How can we reduce losses?
3: Selection of equipment and materials.

When the asphalt mixing plant is running, combustion oil will be used, but the combustion oil is divided into different grades. The key to us is to use it correctly. The following are the specifications for the use of combustion oil in asphalt mixing plants, please be sure to abide by them.

The drying and heating system can be regarded as an important part of the whole, so in actual work, it processes materials in a countercurrent heating manner, thereby fully dehydrating the cold aggregate and heating it at the same time. to a certain temperature, thus providing the necessary conditions for the normal and continuous operation of the asphalt mixing plant.
