The main objective of this research is to evaluate the influence of applying Barley Bran Ash in different percentages on the physical-mechanical properties at the subgrade level, in this specific case applied to the Yaurisque-San Juan de Taray highway; verifying that the soil meets the minimum requirements to be considered material that can be used at the subgrade level, all of this specified in the parameters of the Peruvian standards. Our hypotheses will be demonstrated through laboratory tests, which are: consistency limit tests (liquid limit, plastic limit and plasticity index), humidity-density relationship (Modified Proctor) and Support Capacity of California CBR. Also, it was possible to demonstrate that the present investigation had satisfactory results, although the improvement is not much after all Barley Bran Ash additive improved physicalchemical properties of the soil about which it was applied. Something else that is important to stand out is that Barley Bran Ash was obtained as recycled material from the waste from craft breweries in the city of Cusco. The research has a quantitative approach, since the results obtained were analyzed using variable quantifiers. Furthermore, all hypotheses were developed before the development of the trials. This research focuses only on soil samples obtained from the Yaurisque-San Juan de Taray highway, so the effectiveness of these results on other types of soil is not guaranteed. Barley Bran Ash was used in different percentages: 10%, 15% and 20%, with the most favorable results in the dosage of 10% barley bran ash where the highest result for the CBR is seen with a value of 15.58%, however it was not enough to be able to recategorize the sample, maintaining it as good subgrade (S3) according to the Peruvian Highway Manual (2013). In addition, something to highlight is the high presence of silica within Barley Bran Ash at 58.30%, magnesium (10.90%), calcium (8.10%), aluminum (8.26%), iron (3.20%) that favor the improvement of the physical-chemical properties of the soil at the subgrade level.
