Control of compaction of natural soil (in excavation) or compacted in the embankment during the construction of roads is one of the basic forms of quality control of the substructure. When building high-speed roads (highways and high-speed railways), the priority is to achieve a high level of control over the performed work. In order to prevent dif...
