Fill engineering is widely used across various infrastructures. Compared to bridge and tunnel engineering, it may seem simple, but it is actually quite complex. Its engineering quality is even harder to control. With the development of technology, both the method of fill compaction and the method of quality control have undergone profound changes. Intelligent compaction, as a new technology, integrates compaction and quality control of fill, fully embodying the four basic characteristics of intelligent construction: “perception, analysis, decision-making, execution,” and is a pioneer of intelligent construction.
