Abstract : The stabilization of naturally-occurring or native soil has been performed by millennia.
The Mesopotamians and Romans separately discovered that it was possible to improve the ability of pathways to carry traffic by mixing the weak soils with a stabilizing agent like pulverized lime stone or calcium.
This was the first chemical stabilization of weak soils to improve their load-carrying ability.Successful modern soil stabilization techniques are necessary to assure adequate sub grade stability, especially for weaker and wetter soils.
It is widely recognized that selection between cementitious stabilizing agents cement and lime is based on the Plasticity Index (P I) of the primary soil type being improved.
