Transportation is still the mainstream mode of transportation. However, there are many inspection standards for the laying of highways. One of them is that the ground needs to be treated before the road is laid. During the treatment, the ground needs to be compacted. The compaction degree of the foundation is related to the quality and bearing capacity of the later road. Therefore, the compaction degree of the foundation is highly valued by the quality inspection units.
