Municipal engineering inspection projects:
1. Subgrade: For embankment subgrade, layer-by-layer density and thickness checks are required, and density, settlement, and flatness must be inspected upon reaching the top layer; for excavation subgrade, only the latter few items are directly checked.
2. Underlay: Thickness, Compaction.
3. Compacted Layer: Flatness, Compaction, Thickness, Unconfined Compressive Strength, Cement Dosage.
4. Concrete pavement: Flexural strength, smoothness, core sampling, structural depth.
5. Asphalt Pavement: Deflection, Compaction, Thickness, Skid Resistance, Flatness, Water Permeability.
