Modified asphalt equipment has gradually been widely used. The equipment has diversified configurations and processes, including fixed production, mobile, and main engine import. Generally, the modification of asphalt requires three processes: swelling, shearing, and development. For the modified asphalt system, swelling is closely related to compatibility. Analysis shows that the size of swelling will directly affect the compatibility. Swelling behavior is closely related to the production, processing technology, and high-temperature storage stability of modified asphalt.

Asphalt mixing plants are essential equipment for producing asphalt mixtures. Their site design and construction technical indicators and selection parameters are crucial for ensuring the proper operation and quality of the plant. The following details the relevant technical indicators and selection parameters for the site design and construction of asphalt mixing plants.

I. Applications
1. Widely used for mixing solid-solid (powder-to-powder) and solid-slurry (powder-to-cement) materials such as putty paste, stone paint, dry powder, putty, pharmaceuticals, foods, chemicals, feed, ceramics, and refractory materials. It is particularly suitable for mixing viscous materials.

After the asphalt spreader has been used for a period of time, many stains will be generated around the equipment. If it is not cleaned for a long time, a thick layer will be formed, which is more difficult to clean. Although the cleaning methods are all known, we need to pay attention to some asphalt spreader issues when cleaning the construction.

In recent years, my country's highway construction has boomed. Asphalt pavement, due to its superior driving comfort and performance, has become the preferred material for highway pavements. However, traditional hot-mix asphalt technology leads to severe environmental pollution and energy consumption during construction. Faced with this challenge, scientists are committed to developing environmentally friendly construction methods, leading to the emergence of warm-mix asphalt technology. This technology effectively lowers the mixing and paving compaction temperatures of the asphalt by adding a warm-mix agent during the hot-mixing process, thereby reducing smoke emissions and saving energy. The warm-mix agent reduces the viscosity of asphalt at high temperatures, improving its fluidity, thereby achieving the goal of lowering construction temperatures without compromising the asphalt's road performance.

Asphalt mixing plants are now widely used on construction sites and in various engineering projects. They are applied in many areas and contribute to my country's infrastructure development. However, several aspects need to be considered during use to ensure safer and more worry-free operation.
