Paper Title
The Effect of Lime Rates on the Mechanical Behavior of Clay

Abstract
With the reduction of resources in quality materials, more and more constructions of civil engineering structures are made on low resistance soil, which leads to think of the development of techniques of stabilization of this type of soil. Lime stabilization has been widely applied in civil engineering practice as foundations. With the addition of lime to soils, reactions are established with the soil grains that lead to improved geotechnical properties of the treated soil. An experimental methodology was developed to study the physical and mechanical behavior of mixtures treated by evaluating the influence of a variety of lime percentages on the Atterberg limits, the blue value, the compactibility. A continuous increase in lime of 2 to 10% implies an improvement of the physicomechanical parameters, which means the good behavior of the treated mixtures. The stabilization of the clay-lime matrix is due to chemical reactions between the clay minerals in the soil and the hydrated lime (flocculation and agglomeration, pozzolanic reaction).
