This study presents the efficiency of bioengineering through the cultivation of Kikuyu grasses for the stabilization of slopes on Highway Route PE-28B in Peru. The objective was to evaluate the impact of Kikuyu roots on soil shear resistance and slope stability. Direct cutting tests and global stability analysis were carried out using SLIDE V6.0 software, both in natural conditions and with the intervention of Kikuyu grasses. The results showed that the safety factor (FS) of the slope increased significantly with the presence of Kikuyu roots: from 0.905 to 1.504 according to the Bishop Method and from 0.881 to 1.444 according to the Janbú method in static analyses, and from 0.751 to 1.278 and from 0.728 to 1.218 in pseudostatic analyzes respectively. Furthermore, direct shear tests revealed an increase in friction angle and soil cohesion with the presence of Kikuyu roots. In conclusion, bioengineering with Kikuyu grasses is demonstrated as an effective and sustainable technique to improve slope stability, offering a viable alternative to traditional stabilization methods, with significant economic and environmental benefits.
