Description

Technical Field

[0002] Highway compaction testing is an important part of ensuring road quality and safety. Insufficient compaction may cause settlement, deformation and other problems during the use of the road surface, affecting driving safety. Therefore, accurate testing of highway compaction is crucial.

[0003] In the prior art, the commonly used methods for testing the compaction of highway roadbeds include sand filling method, ring knife method, coring method and the like; however, the above methods are relatively troublesome and require taking out a part of the road surface for testing. According to a Chinese patent application number 201920033063.5, a highway compaction test detection device uses the elastic potential energy of a spring to drive a detection pressure ball to impact the detection area to form a certain depression. The staff can judge whether the compaction of the highway is within the qualified range according to the degree of the depression. Compared with the sampling detection in the prior art, the operation is more convenient;

[0004] However, the above patent still has a disadvantage, that is, it is difficult to keep the compression degree of the spring consistent each time the test is performed; each time the worker needs to pull up the test pressure ball, and then judge the pull-up height of the test pressure ball by the scale line; in this way, the worker needs to visually align the scale while pulling the test pressure ball, which is difficult and hard to align. If the compression degree of the spring is different each time, it will seriously affect the test result; therefore, a highway compaction detection device needs to be improved to address this problem.
