In highway maintenance, the main material of slurry seal technology is emulsified asphalt, and its main functions are as follows:
First, slurry sealing technology improves the waterproofing function of the road surface. This function is inseparable from the diverse composition and small particle size of the slurry mixture. These features allow it to form a tight surface after paving. Materials with smaller particle sizes can improve the bonding degree of the original pavement to a greater extent and better prevent rain or snow from penetrating into the pavement base layer. In short, because the materials of the slurry sealing technology not only have smaller particle sizes but also have a certain gradation, the stability of the pavement base layer and soil layer is greatly improved, and the permeability coefficient of the pavement is reduced.

Certain failures cannot be avoided during the use of the asphalt mixing plant. For example, a malfunction of the cold material feeding device may cause the asphalt mixing plant to shut down. This may be due to a malfunction in the asphalt mixing plant or due to gravel or foreign matter being trapped under the cold material belt. If it is stuck, if it is a circuit failure, first check whether the motor control inverter of the asphalt mixing station is faulty and whether the line is connected or open.

Recently, Sinoroader Company sold a 6m3 slurry sealing truck to a customer from Indonesia to assist in highway maintenance and construction in Southeast Asia.

Synchronous gravel sealing technology has broad prospects. Synchronous gravel sealing technology already has mature application experience in Europe and the United States. Likewise, it is completely suitable for the Chinese highway market. The main basis is as follows:

1: The site should be located on higher ground and away from residential areas and densely populated areas.
Because part of the equipment of the mixing station is installed below the ground, in order to avoid continuous rainfall. The equipment will suffer disaster, and the changing aggregate moisture content will affect the concrete quality. Quality accidents are prone to occur. Therefore, during site construction, attention should be paid to the construction of drainage pipelines and sand and gravel quarries. With the rapid development of cities. As the city continues to expand, environmental protection requirements will become more and more stringent. Gravel vehicles are prohibited from traveling on urban roads, so concrete mixing plants should be built far away from the urban area.　　

In recent years, China has provided a lot of help to Jamaica in terms of infrastructure construction. Some of Jamaica's major highways are constructed by Chinese companies. Jamaica will continue to deepen cooperation with China and hopes that China will continue to invest in infrastructure construction in Jamaica and the Caribbean. Currently, Jamaica is actively promoting the construction of special economic zones and hopes to receive more help from China.
