Key points for small rollers in subgrade construction
Release time:

Small road rollers play a crucial role in road construction, and different attention points are required at various stages of the project. Below, a small road roller manufacturer shares key tips for subgrade construction, hoping to provide valuable assistance to everyone.
1. When using a small roller for subgrade construction, it is essential to first ensure proper drainage facilities to prevent water damage.
2. Before constructing the embankment, first establish boundaries, remove topsoil down to the edge lines, fill in any depressions, level the surface, and then compact it thoroughly to ensure the embankment remains stable and does not settle.
3. A small roller manufacturer reminds you to carefully select the subgrade fill material to ensure soil stability and that its strength and particle size meet the construction requirements.
4. When constructing embankments, the new and old interfaces of adjacent stepped fills must be properly connected. On sloping surfaces, step-like trenches should be excavated, and stepped sections left in place during segmented filling. At the same time, construction layers should overlap seamlessly.
5. For embankments constructed with mixed fill materials of varying soil types, the fill should be layered according to soil characteristics, using strength and permeability as key criteria, to prevent instability in the subgrade.
