In the production process of asphalt mixture, there are often some factors that affect its production quality. For example, the bag dust collector of the asphalt commercial concrete station will cause the emission to fail to meet the emission standards due to a large amount of high-temperature gas and dust. Therefore, the dust collector must be treated reasonably and effectively to ensure its normal operation and meet the emission requirements. Bag dust collectors have great advantages, such as strong adaptability, simple structure and stable operation, so they are widely used in the treatment of emissions. However, there are still many shortcomings in bag dust collectors, and effective measures must be taken to maintain them reasonably to ensure their efficient operation.

Pavement preventive maintenance is a periodic mandatory maintenance measure that is taken to restore the service function of the pavement surface when the structural strength of the pavement is sufficient and only the surface function is attenuated. A series of new preventive maintenance technologies such as ultra-viscous fiber-added low-noise micro-surfaces and synchronous gravel seals have been widely used on the main lines of national highways, and the construction results have been widely praised by customers.

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

Asphalt mixing equipment (asphalt concrete mixing equipment) all work in open-air sites, with heavy dust pollution. Many parts work in high temperatures of 140-160 degrees, and each shift lasts up to 12-14 hours. Therefore, the daily maintenance of the equipment is related to the normal operation and service life of the equipment. So how to do a good job in the daily maintenance of asphalt mixing station equipment?

Treatment of the heavy oil combustion system failure in asphalt mixing station
An asphalt mixing station (hereinafter referred to as the mixing station) used by a certain unit uses diesel as fuel in production. As the market diesel price continues to rise, the operating cost of the equipment is getting higher and higher, and the efficiency is constantly decreasing. In order to reduce production costs, it is decided to use a low-priced, combustion-friendly and qualified special combustion oil (heavy oil for short) to replace diesel as fuel.

Gravel seal technology is a thin-layer construction technique used to establish road surface functionality. The basic method is to first spread an appropriate amount of asphalt binder evenly on the road surface through special equipment, then densely distribute gravel with relatively uniform particle size on the asphalt layer, and then roll it so that an average of about 3/5 of the gravel particle size is embedded. Asphalt layer.
Gravel sealing technology has the advantages of excellent anti-slip performance and effective water sealing effect, low cost, simple construction technology, and fast construction speed, so this technology is widely used in Europe and the United States and other countries.
