Soil stabilisation with lime – UNIROAD™

Clayey soil stabilisation with lime is a widespread technique which is universally accepted and has been requested for years in contracts with entities of national importance (ANAS and RFI – add link).
The enormous advantage it offers is the possibility to process and use soil that would otherwise be sent to a landfill.
The documentation viewable here contains details of all the processing stages, which are:

  • Soil analysis
  • Determination of the quantity of lime to be used depending on the destination of the treated material (modification or stabilisation)
  • Preparation of the site area (topsoil removal and moisture analysis)
  • Liming the ground according to the directions given by the laboratory
  • Mixing the soil with lime
  • Compaction
  • Next layer or coverage

The type of lime that is used most is calcium oxide, commonly known as quicklime. Hydrated lime, the slaked type of oxide, is equally effective but economically unattractive because much lighter and more voluminous than its reactive type.
Specifications and reference standards: CE marking and CL 90 classification (as defined in the Building Lime Standard 459). (Diagram CL90)
