[0002] Asphalt concrete is a composite material composed of materials such as aggregates, asphalt, and additives, and is usually used for road paving and repair. The construction of asphalt concrete generally includes processes such as mix design, raw material preparation, mixing, paving, and compaction. Asphalt concrete has excellent water resistance, durability, and crack resistance, and is a commonly used material in road paving and repair. When asphalt concrete is used, its fluidity usually needs to be detected, and the fluidity test is one of the important indicators for evaluating the quality and construction performance of asphalt concrete.
