Key Points of Small Roller in Subgrade Construction
Small road roller plays an important role in road construction, in different stages of construction, there are different points of attention. The following is a small road roller manufacturers to introduce the key points of subgrade construction, hoping to help you.
1. When using small road rollers for subgrade construction, it is necessary to ensure good drainage facilities to avoid water immersion.
2, subgrade filling before the embankment construction first put the boundary, remove the topsoil to the side line, fill the hole leveling and compaction, embankment stability without subsidence.
3. Small roller manufacturers remind you that the roadbed filler must be selected to ensure the stability of the soil and the strength and particle size can meet the construction requirements.
4, embankment filling ladder overlap each other new and old interface to connect, slope excavation steps, sectional filling left ladder, while the construction layer is stacked.
5, different soil mixed embankment embankment fill is not the same, according to the soil quality of the layer, strength permeable as the basis, to prevent the subgrade instability.
