It is known for many years, the procedure to mix lime to him to a plastic clay, in order to lower its plasticity as well as to increase its capacity to support efforts. And also, during many years, a series of procedures has been standardized to carry out this incorporation, to manage to obtain a homogenous mixture as well as to establish some type of control that allows to verify results us. Also the great difficulties have been legendary that must when trying apply the procedures established in a certain work. Different procedures have been proven to obtain a uniform mixture of lime and clay. It has been tried for example, to disintegrate a plastic clay layer being used from agricultural plows, happening through motoconformadoras to the use of diverse machines with disgregadores drums of varied so large and designs.
Once disintegrated the clay layer, it has been tried to incorporate a certain percentage to him of lime, being followed diverse instructions or that they indicate that the lime is handled in coats and the content of them is distributed according to a grid previously drawn up and calculated to have a relation according to the percentage that will have to be applied, or by some other procedures that can include in bulk until the application of the lime. Already the value of its Limits of Consistency is perfectly known that the lime builds a favorable effect in the behavior of a plastic clay, when modifying (Limits of Atterberg). In infinity of taken tests I finish during the course of the time, has been that the value of the Liquid Limit of a plastic clay tends to be increased when this clay is mixed with lime. When taking place this increase in the value of the Plastic Limit, consequently logical, the Plastic Index will tend to fall of value, which as well means that the plastic behavior of the treated clay improves, for the generally looked for aims in the construction.
