The present investigation is mainly related to the use of the Standard Penetration Test (SPT) and the Direct Shear Test, through these tests results were obtained that were used to formulate a correction expression. The study was carried out on sandly soils with a percentage of fine less than 12 % in the Lima districts of Villa El Salvador and Ventanilla. Due to the great diffusion and use of the Direct Shear Test it is of utmost importance that the results obtained are as reliable as possible, since it depends on the design of foundation structures, slopes, embankments, among others. However, there is great difficulty in obtaining undisturbed samples from sandy soils, which induces to Direct Shear tests being carried out, reshaping the specimen to its natural density, moisture content, compactness and others, this could generate a considerable variation in the results (soil resistance parameters). Based on the above, it is considered necessary to find a way to counteract this problem, for this reason it is proposed to formulate a correction expression for the friction angle obtained in the Direct Shear tests of remoulded samples. For the formulation of said expression, the Microsoft Excel program was used to perform a multiple linear regression with the variables related to the friction angle, resulting in a correction expression that improves the friction angles of the Direct Shear Test by 63.69 %.
