During the construction, there are problems involved on the ground where the pavement structure will be place. One of these problems is the load bearing capacity of the soil measured by the CBR value. The Ministerio de Transportes y Comunicaciones required in the Manual de Carreteras MC-05-14 that the minimum CBR value to be part of subgrades in pavement structure is 6%. In the city of Iquitos, we can find soils mainly composed of clays which are characterized by having a CBR value under what is required by MTC. Therefore, an increase in the load bearing capacity of this soils is necessary to be accepted as a subgrade in pavement structures. The present study proposes the addition of cationic bitumen emulsion in percentages of 2%, 3% and 4% to the clay soil sample collected in the city of Iquitos. The parameters will be evaluated from the results obtained by the Proctor modified test and CBR test. The results showed that the CBR increased to values of 7.6%, 11.8% and 15.5% with the addition of cationic asphalt emulsion in percentages of 2%, 3% and 4% respectively. Finally, the study concludes that adding the cationic bitumen emulsion the CBR value of the clay soil increase up to 6% required by the MTC to be accept as a subgrade of pavement structure.
