Description

Technical Field

[0001] This utility model relates to the field of compaction testing technology, specifically a highway compaction testing device. Background Technology

[0002] Compaction of highway subgrade and pavement is the most critical process in highway subgrade and pavement construction. The degree of compaction is one of the key indicators for inspecting the construction quality of highway subgrade and pavement. The higher the degree of compaction, the greater its density, the better the overall performance of its materials, and the longer the service life of the highway. Therefore, improving the degree of compaction can effectively enhance the strength and stability of the highway subgrade. Thus, accurate testing of the degree of compaction is very important.

[0003] The sand-filling method is a commonly used approach. A suitable hole is excavated at the testing location, and standard sand is poured into the hole. The volume of the hole is calculated based on the density of the sand and the mass of sand poured into the hole. The mass of the sample taken from the hole is then weighed, and the density and compaction degree of the road are thus determined. This method is relatively accurate.

[0004] Manual drilling requires a variety of tools and is time-consuming and labor-intensive. Mechanical drilling usually uses drill bits, which can easily damage the inner wall of the hole during the drilling process, making the surface of the inner wall uneven and resulting in non-standard volume inside the hole, thus affecting the test data.
