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.

The surface coating is to apply a reducing agent that can partially or fully restore the performance of aged asphalt to the aged asphalt pavement. Through the penetration of the reducing agent, it penetrates into the asphalt surface layer to a certain depth and interacts with the aged asphalt paste. The polymerization reaction occurs, causing the components of aged asphalt to undergo reverse changes, restoring flexibility, reducing brittleness, and at the same time protecting unaged asphalt to delay aging. Surface coating is suitable for pavements where the asphalt pavement is obviously aging, and the pavement has a wide range of slight cracks and local looseness. There are two types of surface coatings, one is the fog seal layer and the other is the reducing agent coating. Today we will focus on understanding the fog seal layer.

When operating solder evaporation equipment, you need to pay attention to safety and follow correct operating procedures and procedures. First, you need to check whether the equipment is intact, then turn on the heating system, and wait for the equipment to reach the appropriate temperature before adding solder. Stir continuously during the feeding process to prevent the aluminum alloy from agglomerating. Clean the equipment promptly after use and keep the equipment clean and hygienic.

Nowadays, asphalt pavement is widely used in road construction due to its many advantages. At present, we mainly use hot bitumen and emulsified bitumen in the construction of asphalt pavement. Hot bitumen consumes a lot of heat energy, especially large quantities of sand and gravel materials that require baking heat. The construction environment for operators is poor and the labor intensity is high. When using emulsified bitumen for construction, heating is not required and it can be sprayed or mixed for paving at room temperature, and pavement of various structures can be paved. Moreover, emulsified bitumen can flow by itself at room temperature, and can be made into emulsified bitumen of different concentrations as needed. It is easy to achieve the required asphalt film thickness by pouring or permeating the layer, which cannot be achieved by hot bitumen. With the gradual improvement of the road network and the upgrading requirements of low-grade roads, the use of emulsified bitumen will become larger and larger; with the enhancement of environmental awareness and the gradual shortage of energy, the proportion of emulsified bitumen in asphalt will become higher and higher. The scope of use will also become wider and wider, and the quality will become better and better. Emulsified bitumen has the characteristics of non-toxic, odorless, non-flammable, fast drying and strong bonding. It can not only improve road quality, expand the scope of asphalt use, extend the construction season, reduce environmental pollution and improve construction conditions, but also save energy and materials.
