Description

A kind of excavator for subgrade compactness detection

technical field

The utility model belongs to the technical field of roadbed compaction detection, and more specifically relates to a soil borrower for roadbed compaction detection.

Background technique

Subgrade compaction (formerly: refers to the ratio of the dry density of soil or other road construction materials after compaction to the standard maximum dry density, expressed as a percentage.) Subgrade compaction is one of the key indicators for the quality inspection of subgrade pavement construction , to represent the density status after on-site compaction. The higher the compaction degree, the greater the density, and the better the overall performance of the material. When testing the compactness of the roadbed, the sand filling method is usually used. The sand filling method is to punch the test roadbed hole, and use uniform particle sand to replace the volume of the test hole. It is the most common method at present. Many projects have listed the sand filling method as the main method for on-site density determination. This method can be used to test various soil or pavement materials density of.
