This approach involves several
advantages, especially for the environment:
Recovery of silt-clayey materials
in site;
Clear separation between worked layers
and below layers, with no use of geotextile materials;
Significant increase of CBR index;
Significant increase of erosion
resistance;
Significant increase of freezing / thawing
resistance;
Slow and constant hardening process due
to chemical processes activated by pozzolanic binder reactions
in clayey minerals and siliceous components of grounds
when mixed with lime;
