Asphalt concrete is widely used in road construction, extending the lifespan of roads and reducing the impact on road surfaces during vehicle travel. Additionally, it is suitable for airport runways to ensure safe take-offs and landings; for bridge construction to enhance durability and load-bearing capacity; and for parking lot construction due to its ability to withstand heavy vehicle loads and resistance to damage. Moreover, asphalt concrete can also be used for building oil separators, storm drain systems, and other environmental facilities, as well as for nuclear waste storage facilities.

Asphalt concrete is a high-performance pavement material with broad application prospects. In the manufacturing...During the preparation, paving, and compaction processes, strict control of all parameters and quality requirements should be maintained to ensure the quality and safety of the road surface.
