Background

The detection frequency in the highway engineering construction technical specification is mainly determined for better controlling engineering in construction, and the inspection and evaluation standard is the most basic frequency determined for evaluating the engineering quality. The degree of compaction, also known as degree of compaction, refers to the ratio of the dry density of the soil or other road material after compaction to the standard maximum dry density, expressed as a percentage, and the determination of the degree of compaction mainly includes the determination of the indoor standard density (maximum dry density) and the field density test. The compactness is one of key indexes for detecting the construction quality of the roadbed and the pavement, the compactness condition after on-site compaction is represented, and the higher the compactness is, the higher the density is, and the better the overall performance of the material is. For roadbed, semi-rigid base course of road surface and flexible base course of granular material, the compactness is the ratio of dry density actually reached in construction site to the maximum dry density obtained by indoor standard compaction experiment; for asphalt surface course and asphalt stabilized base course, the degree of compaction is the ratio of the density achieved on site to the indoor standard density.

In the prior art, tamping is mostly carried out by adopting a tamping method, and a heavy hammer tamping method is a foundation treatment method for enabling a soil layer in a certain depth under the ground to be in a compact state by utilizing impact energy generated when a heavy hammer freely falls from high altitude. The effective tamping depth depends on the weight of the hammer, the diameter of the bottom of the hammer, the drop distance and the soil. The heavy hammer tamping method can improve the bearing capacity of the foundation and eliminate the collapsible phenomenon of the collapsible foundation.
