[0002] Recycled aggregate from cement-stabilized crushed stone refers to the aggregate obtained from crushing old cement concrete pavements. This method is used to prepare new cement-stabilized crushed stone layers. This method has important applications in road construction and maintenance. The compaction of recycled aggregate from cement-stabilized crushed stone approaches density, and its strength is primarily due to the interlocking effect between the crushed stones, while sufficient mortar volume is required to fill the gaps between the aggregates. It has high initial strength, which increases with age, quickly forming a slab, resulting in high strength, good impermeability, and frost resistance.

[0003] During specific use, the water-stabilized crushed stone recycled large aggregate needs to be screened before use, so that aggregates of different particle size levels can be obtained to meet the needs of different projects. However, the screening plate on the water-stabilized crushed stone recycled large aggregate screening device is not easy to replace, which makes it difficult for the screening device to screen water-stabilized crushed stone recycled large aggregates of different particle sizes, reducing the practicality of the water-stabilized crushed stone recycled large aggregate screening device.
