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.

Fog sealing is a road maintenance method with a wide range of applications. Mainly used on roads with light to moderate fines loss or loose material. For example, when the asphalt pavement is loose, the fog seal layer can solve the problem; such as the surface of dense-graded asphalt mixture on aging pockmarked surface, the surface of gravel seal layer, the surface of open-graded asphalt mixture, etc. It mainly refers to the fact that the road surface has begun to show slight fatigue cracks and fine aggregate loss, and its water permeability has increased. Pavement water will enter the asphalt mixture through cracks or fine aggregate damage, causing cracks, cracks, and Potholes and other pavement conditions where the pavement structure performs well.

The technical feature of the simultaneous gravel sealing technology is that one equipment can spread the bonding material and stone at the same time. The asphalt and stone must be combined within one second. The temperature of the hot asphalt is 140°C when the bonding material is sprayed, and the temperature can be guaranteed to be above 120°C during bonding. The asphalt temperature drops very little. At this time, the fluidity of the asphalt binder is still very good, and the bonding area with the stone is large, which enhances the bonding with the stone. The strength of the stone bond. The traditional surface sealing technology generally uses two different equipments and two processes for spreading construction. Such a long construction time interval will cause the temperature of the asphalt to drop by about 70°C, and the bonding effect between the stone and the asphalt will be poor, resulting in a large loss of stone and affecting the performance of the sealing layer.

The type of mixture used for slurry seal construction is selected based on factors such as usage requirements, original road conditions, traffic volume, climate conditions, etc., and the mix ratio design, road performance test and design parameter test of the mixture are carried out, and the mix is ??determined based on the test results. Material mix ratio. This process is recommended to be equipped with a mineral screening machine to screen stones.
Specific precautions are as follows:
