[0002] The roadbed compaction layer refers to the roadbed soil layer that has been compacted. It is located above the soil and stone materials and provides a solid foundation for the pavement structure layer. The roadbed compaction layer is usually formed by compacting the soil and stone materials with compaction equipment. During the compaction process, the air in the soil is removed, the porosity is reduced, and the density and stability are increased. The thickness of the roadbed compaction layer is one of the important indicators to measure the quality of road construction.
