Information
Small roller plays an important role in road construction, and has different points of attention in different stages of construction. The following is the introduction of small roller manufacturers to the key points of subgrade construction, hoping to help you.
 
 
 
1. When small roller is used for subgrade construction, drainage facilities shall be ensured to avoid water immersion.   
 
2. Before subgrade filling, the embankment construction shall be set out first, the topsoil shall be removed to the side line, the filling hole shall be leveled and compacted, and the embankment shall be stable and free from subsidence.
 
3. The small roller manufacturer reminds you that the subgrade filler must be selected well to ensure the stability of the soil and the strength particle size can meet the construction requirements.
 
4. The new and old interfaces of the embankment filling steps shall be connected with each other. The steps shall be excavated on the slope surface, and the steps shall be reserved for the section filling. At the same time, the construction layers shall be overlapped.
 
5. The filling of embankment with different soil is different. According to the soil quality, the layers are divided and the strength is permeable to prevent the subgrade from instability.
