Slurry seal is to use mechanical equipment to mix appropriately graded emulsified asphalt, coarse and fine aggregates, water, fillers (cement, lime, fly ash, stone powder, etc.) and additives into a slurry mixture according to the designed ratio and evenly spread it on the original road surface. After wrapping, demulsification, water separation, evaporation and solidification, it is firmly combined with the original road surface to form a dense, strong, wear-resistant and road surface seal, which greatly improves the performance of the road surface.

Chip seal technology is a thin layer construction technology used to establish road surface functions. The basic method is to first spread an appropriate amount of asphalt binder evenly on the road surface through special equipment, and then spread the relatively uniform particle size of crushed stones densely on the asphalt layer, and after rolling, an average of about 3/5 of the crushed stone particles are embedded in the asphalt layer.

Emulsified bitumen production equipment is a mechanical device used to disperse tiny droplets of bitumen in an aqueous solution containing an emulsifier after hot melting and mechanical shearing, thereby forming an oil-in-water bitumen emulsion. Do you know what performance characteristics it has when in use? If you don't know, follow the technicians of Sinoroader Group to take a look.
The technicians of Sinoroader Group, a manufacturer of emulsified bitumen production equipment, summarized the characteristics of emulsified bitumen production equipment into the following 3 points:

Users who have used slurry seal know that it is a cold-mix fine-grained asphalt concrete thin layer construction technology with (modified) emulsified asphalt as a bonding material. Do you know what it does? If you don't know, follow the editor of Sinoroader Group to learn about it.
1. Filling effect. Since the emulsified bitumen slurry mixture contains more water and is in a slurry state after mixing, the slurry seal has a filling and leveling effect, which can fill the fine cracks on the road surface and the uneven road surface caused by loose detachment to improve the flatness of the road surface.

Asphalt mixing plants will generate a lot of dust and harmful exhaust gas during construction. In order to reduce the harm caused by these pollutants, relevant dust removal equipment is generally configured for treatment. At present, two types of dust removal devices, consisting of cyclone dust collectors and bag dust collectors, are usually used to collect pollutants as much as possible to reduce pollution and meet the standards of environmental protection regulations.
However, in this process, the selected dust removal equipment must meet certain requirements. Especially for the selection of filter materials, because after a period of use of asphalt mixing plant equipment and machine bag dust collectors, the filter materials will be damaged due to some reasons and need to be repaired or replaced. Therefore, which filter material to choose is a question worth thinking about. The usual way is to choose according to the provisions and requirements of the equipment's instruction manual or maintenance manual, but it is still not ideal.

Asphalt mixing plants are also called asphalt concrete mixing equipment, which plays an important role in pavement construction. This set of equipment specializing in the production of asphalt concrete can be divided into many forms. Asphalt mixing plants can produce asphalt mixtures and colored asphalt mixtures, etc. So, what problems should be paid attention to when operating such equipment? First of all, after starting the equipment, it should be run at no load for a period of time.
