The base layer of asphalt pavement is divided into semi-rigid and rigid. Since the base layer and the surface layer are materials of different properties, good bonding and continuity between the two are the top requirements for this type of pavement. In addition, when the asphalt surface layer seeps water, most of the water will be concentrated at the joint between the surface layer and the base layer, causing damage to the asphalt pavement such as slurry, looseness, and potholes. Therefore, adding a lower seal layer on top of a semi-rigid or rigid base layer will play a vital role in enhancing the strength, stability and waterproofing capabilities of the pavement structural layer. The more commonly used one is to use asphalt gravel synchronous sealing technology.

Many of today's asphalt mixing equipment are green and environmentally friendly products, and bottom-silo asphalt mixing plant is a relatively representative one. Whether it is its structural design or technical processing, it is based on energy conservation and environmental protection as the basic principle.

Asphalt spreading trucks are used to spread the permeable oil, waterproof layer and bonding layer of the bottom layer of asphalt pavement on high-grade highways. It can also be used in the construction of county and township-level highway asphalt roads that implement layered paving technology. It consists of a car chassis, an asphalt tank, an asphalt pumping and spraying system, a thermal oil heating system, a hydraulic system, a combustion system, a control system, a pneumatic system, and an operating platform.

As the main equipment for asphalt processing, asphalt mixing plants are used in many engineering constructions. Even though there have been many improvements in the performance and quality of the equipment, its pollution problem is still very serious. Obviously this is inconsistent with our environmental protection and energy saving requirements. I wonder if there is a special environmentally friendly asphalt mixing plant?

The entire asphalt mixing plant also includes the heating tank, and the quality of the final product is closely related to the correct use of the bitumen heating tank. The following are specific operating specifications for your reference.

As road maintenance becomes increasingly important, slurry sealing trucks play a huge role in road maintenance. In highway maintenance, the main material of slurry sealing technology is emulsified asphalt, and its main functions are: The following aspects.
