Common treatment methods for special roadbeds

Some of the very common conclusions of common treatment methods for special roadbeds include:

1. For the base sections near towns and roads overpasses, flooded water, reservoirs and flooded roads, the slopes of the embankment shall be protected by framework protection slopes, slurry rubble protection slopes, and dry rubble protection slopes.

2. For road base sections filled with silt, silty clay, powder and fine sand with a height of more than 5m, embankment slope reinforcement works mainly include geogrids and other treatment methods.

3. For the saline soil roadbed, it is mainly used to remove and replace, composite geomembrane cutoff method.

4. For soft ground treatment in flood alluvial areas, treatment methods such as excavation and replacement, geogrid, and strong concrete are mainly used.

5. For soft soil foundation treatment, heavy-duty roller compaction and geogrid methods are mainly used.

6. Geogrids and strong concrete are mainly used in seismic liquefaction areas.

7. For wind-blown roadbeds, it is mainly used in the treatment of neutral reed square sand barriers, reed square sand barriers, and block slab slopes.

8. For wind-sand flow subgrade projects, the treatment methods include sloping board slopes, neutral reed square sand barriers, reed square sand barriers, and geogrid.

9. For wind erosion roadbed construction, the method is mainly used for the treatment of the slope block, geogrid, and widening of the base surface.

10. For expansive soils (rocks), the use of subgrade replacement, anti-seepage composite geomembrane, mortar and chipping stone retaining wall, and skeleton slope protection are mainly used for the treatment of expansive soil (rock).

11. For wind-blown snow roadbed, the main use is to slow down the slope of the roadbed, set aside a wide platform, and set up a snow fence.
