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:

Selection of large-scale asphalt mixing equipment High-grade highways have strict requirements for black pavement equipment. Mixing, paving, and rolling are the three main processes of mechanized pavement construction. Asphalt concrete mixing equipment is an important factor in determining progress and quality. Mixing equipment is generally divided into two categories, namely continuous and intermittent. Due to the poor specifications of domestic raw materials, high-grade highways do not use the continuous roller type and require the forced intermittent type. There are many types of asphalt mixing equipment, with different mixing and dust removal methods, and different site requirements.

Analysis of common faults in asphalt mixing plants
In asphalt pavement construction, asphalt concrete mixing plants are key equipment to ensure construction quality and improve efficiency. In the construction of domestic high-grade highway pavements, almost all imported asphalt mixing plants are used. The general specifications are more than 160 hours. The equipment investment is large and is a very critical part of the pavement construction technology.
The efficiency of the asphalt mixing plant and the quality of the concrete produced are related to whether the asphalt concrete mixing plant fails and the type and probability of failure. Combining many years of experience in asphalt concrete production and electric flat truck construction, the causes of failures in asphalt concrete mixing plants are analyzed to provide some experience in promoting the development of asphalt concrete and ensuring the construction quality of high-grade asphalt pavement.

Asphalt mixture mixing equipment is a proportion of the investment in asphalt mixture mixing plants. It not only affects the normal production, but also directly determines the quality of asphalt mixture and the cost of use.
    The model of asphalt mixing equipment should be scientifically and rationally selected based on the annual output. If the model is too large, it will increase the investment cost and reduce the effective use efficiency of polyurethane products; if the equipment model is too small, the output will be insufficient, resulting in the failure to improve construction efficiency, thereby prolonging the operation time. , poor economy, construction workers are also prone to fatigue. Asphalt mixing plants below type 2000 are usually used for local construction roads or municipal maintenance and repairs, while type 3000 or above are mostly used in large-scale road projects such as highways, national highways, and provincial highways. Usually these projects have tight construction periods.
