Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a cement-stabilized crushed stone material performance detection device. Background Art

[0002] Cement-stabilized crushed stone uses graded crushed stone as aggregate, employing a specific amount of cementitious material and sufficient mortar volume to fill the gaps between the aggregates. The material is spread and compacted using the interlocking principle. This achieves a near-perfect density, with strength primarily relying on the interlocking principle between the crushed stone and sufficient mortar volume to fill the gaps between the aggregates.

[0003] Before cement-stabilized gravel materials are put into construction and use, their impermeability needs to be tested. However, the thickness of the cement-stabilized gravel boards used for testing varies, making them difficult to fix during testing. In addition, water can easily flow directly down from the cement-stabilized gravel boards during testing, which can lead to deviations in the impermeability test results. Utility Model Content
