For strengthening the road base, improving the subgrade, and taking soft-ground measures with a treatment thickness of 30 to 100 cm


This is a construction method that stabilizes the existing subgrade soil by adding and mixing cement and lime in situ. The finished thickness of one layer is 30 to 100 cm.


  1. It is possible to improve the existing subgrade to a subgrade with greater bearing capacity, making it possible to reduce the thickness of the pavement and making it more economical.
  2. Since it is possible to improve the soft subgrade without replacing it, no excavated soil is generated and the construction process can be shortened.


  • Improving the soft subgrade
  • Reducing the thickness of the pavement by increasing the bearing capacity of the subgrade
