This research work fulfills the purpose of determining to what extent the Physical-Mechanical properties of clayey soils of Av. Primavera of the APV are modified. Pillao Matao of the district of San Jerónimo - Cusco for subgrade purposes for pavements, by adding Pino Colophony as an improving agent in the amounts of 3%, 5% and 7%, for which laboratory tests were carried out, according to the “Manual de Ensayo de Materiales” (2016). The approach with which this research has been carried out is of a quantitative nature, due to the fact that during the performance of the different activities, data corresponding to each combination percentage have been recorded, which are contrasted with the hypotheses based on the processed and obtained results. In relation to the scope, it should be noted that the main Physical-Mechanical characteristics of Clay Soil in combination with Pine Rosin are described. We worked only with clay samples, obtained at Av. Primavera in the district of San Jerónimo, in combination with the mentioned percentages. Regarding the results obtained from the standard sample and the samples with Pine Rosin at 3%, 5% and 7%, it is concluded that the Granulometry does not present representative variations, meanwhile the percentages of the Consistency Limits were reduced. Regarding the unaltered samples, the Maximum Dry Densities experienced a certain decrease, mainly due to the incorporation of the improving agent, this resource, being an input of lower density than that of the compacted clay soil, causes lower densities to be obtained. Regarding the Maximum Dry Density of 1.77 gr/cm3 (pattern sample), the densities obtained experience a decrease between 0.03 – 0.07 gr/cm3. In relation to the Optimum Moisture Content of 18.00% (pattern sample), the percentages are reduced to 17.43%, 17.11% and 16.78%, with respect to the addition of Pine Rosin at 3%, 5% and 7% respectively. For the results of the CBR tests, the improvement produced by the Pine Rosin on the evaluated samples stands out, changing the CBR value, from a Poor Subgrade with a CBR of 4.00% (pattern sample), to a corresponding value of a Regular Subgrade; from the first application of 3%, a CBR of 6.74% is provided, with 5% a CBR of 7.49% is obtained and with 7% a CBR of 8.25% is obtained, which exceeds the 6% required by the MTC standard, having the certainty that Pine Rosin can be used as an improving additive for clay foundations in road works.
