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. 

The manufacturer shares with you the function of asphalt melting equipment, which is mainly used to heat and melt asphalt to meet the needs of construction or use. This kind of equipment usually uses electric heating or gas heating, and has the characteristics of energy saving, environmental protection and so on. The use of asphalt melter equipment can greatly improve construction efficiency, reduce energy consumption, and at the same time ensure construction quality. In addition, this kind of equipment can also be used in road maintenance, pavement repair and other fields, and has broad application prospects.

According to statistics, about 80% of the high-grade highways that have been completed and opened to traffic in our country are asphalt pavements. However, with the development of time, the influence of different climatic and environmental factors, and the action of high-intensity driving loads, the asphalt pavements will deteriorate. Different degrees of degradation or damage occur, and pavement maintenance is to adopt effective technical means to slow down this degradation so that the pavement can provide good service quality during its service life.

An asphalt concrete mixing plant plus auxiliary machinery can complete the production process of asphalt concrete mixture from raw materials to finished materials. Its nature is equivalent to a small factory. Regarding the entire production process of the asphalt plant, we summarize the factors that affect production quality into 4M1E according to the traditional method, namely Man, Machine, Material, Method and Environment. Strict independent control over these factors, changing post-inspection to in-process control, and changing from managing results to managing factors. The influencing factors are now stated as follows:
