Asphalt mixer is a high-efficiency mixing equipment specifically designed to mix asphalt, aggregates, and other substances in a certain ratio to form asphalt concrete. Its working principle is to mix liquid asphalt with dry aggregates and mineral powders through the internal mixing system of the equipment at a specified temperature and time, generating an asphalt mixture that meets the specifications.

Asphalt mixer has a wide range of applications in various engineering projects, mainly including the following aspects:

1. Road construction: Asphalt mixers are widely used for laying asphalt pavement on highways, urban roads, and bridges. The asphalt concrete produced by the mixer has excellent durability and compressive strength, which can meet the high-strength requirements of road use.

2. Airport runway construction: Airport runways have extremely strict quality requirements for road surfaces, and asphalt mixers can accurately control the mixing ratio to produce high-quality asphalt concrete, ensuring the smoothness and durability of the runway.

3. Municipal engineering and repair engineering: Asphalt mixer is used in municipal engineering to repair old roads, especially in urban environments. The mixer can provide high-quality asphalt mixture for areas with high traffic flow, improve the service life of the road surface, and reduce maintenance costs.

4. Special purpose pavement: On some special purpose roads, such as highways, heavy-duty roads, etc., asphalt mixers can provide asphalt concrete with higher strength and stronger fatigue resistance, ensuring the stability of the pavement under extreme conditions.

These designs enable the asphalt mixer to not only operate but also maintain smooth operational performance, meeting the needs of various engineering projects.
