The present investigation presents the influence on the mechanical behavior of a soil from the Caserio de Callampampa, Llama, Cajamarca by adding powder rubber. This soil is low plasticity clay and its physical parameters were determined with the tests, such as Granulometric Analysis by means of the Hydrometer (MTC E 109-2016) and by Screening (MTC E 107-2016, NTP 339.128) and the determination of the Limit Liquid, Plastic Limit and Plasticity Index (NTP 339.129). The Modified Proctor (NTP 339.141) and Shear Box (NTP 339.171) test was performed as part of the methodology in order to know the mechanical parameters of the samples and explain the influence caused by the crushed rubber in the shear strength, cohesion, friction angle, etc. The samples tested were that of natural soil (S100) and mixtures with the addition of crushed rubber at 0.5%, 1.5%, 2.5% and 3.5%. The results obtained indicate that the maximum dry density offered by the S100 / C3.5 mixture is increased by 1.76% with respect to the S100 sample and the optimum moisture content decreases by 5.75%. Likewise, the resistance to shear stress offered by the S100 / C3.5 mixture is increased by 35.2% compared to the S100 sample, cohesion increases by 64% and the friction angle decreases by 9.1%. On the other hand, for the CBR test the results obtained in the Modified Proctor tests will be required to find the parameters of the soil at the shear strength and see the viability as a terrain for a subgrade. The percentages were 1.5%, 2.5% and 3.5% whose results are compared with respect to natural soil. The results obtained from the 2 mm CBR of penetration with 95% of M.D.S was for an S100 of 3.3% and with the mixture of S100 / C3.5 it was increased to 9.4%. In conclusion, the clay floor of low plasticity improves its mechanical properties when crushed rubber is added.
