[0002] When the asphalt pavement is hot-regenerated in situ, the loosened old asphalt mixture is transported through the spiral blade and scraper lifting feeder, which will produce old asphalt clumps with very low strength composed of fine materials and old asphalt. The old asphalt clumps are spread on the road surface as large-particle aggregates. After being rolled by a steel wheel roller, oil spots will appear on the asphalt pavement, affecting the performance of the recycled pavement.

[0003] In addition, during the paving process of recycled asphalt mixture, the old asphalt fine material will often accumulate at the bottom of the hopper, causing the hopper to be blocked. This often happens when the asphalt mass is too viscous, too cold, or the angle of the hopper is not steep enough. Once the hopper is blocked, it will affect the construction quality and efficiency of the asphalt pavement, and in severe cases, it may lead to a large amount of asphalt material being wasted.
