Comparative for obtaining the optimum dosage of the soil-cement in clays of high and low plasticity

Dosage is a technique to modify and improve the conditions of the soil-cement that comply with the conditions of the "Instituto Nacional de Vías" standard and in the same way, is economic to be implemented in different types of clay. The clay was classified depending on its plasticity (high plasticity and low plasticity) and the behavior at loads; making laboratory tests of modified proctor, compaction and CBR% for the clays with 4% of soil cement; at the same time, the results of CBR% of soil cement of 4% with natural soils, of 6% of cement and 1 were compared. In this way, was made a proposal of the elaboration of each type of soil-cement with its respective percentage, concluding that the clay of high plasticity can be used for subgrade and the one of low plasticity has a weak bearing capacity
