How to evaluate the compaction effect of a single-wheel vibratory roller?

1. Density detection: Use equipment such as sand filling method, ring knife method or nuclear density meter to measure the density of the compacted material. The higher the density, the better the compaction effect.
2. Settlement observation: Before and after compaction, measure the elevation change of the ground and calculate the settlement. Smaller settlement usually indicates better compaction effect.
3. Bearing capacity test: Evaluate the bearing capacity of the compacted foundation or road surface through methods such as bearing plate test or deflection test. The stronger the bearing capacity, the better the compaction effect.
4. Appearance inspection: Observe whether the compacted surface is flat and solid, and whether there are defects such as looseness, cracks or peeling. Good surface quality usually means better compaction effect.
5. Rebound modulus determination: Measure the rebound modulus of the material. The larger the value, the stronger the material's ability to resist deformation and the better the compaction effect.
6. Moisture content detection: Detect the change in moisture content of the material before and after compaction. Appropriate moisture content and uniformity will help improve the compaction effect.
