This work presents the design of micropiles with fiber-reinforced polymers as a deep foundation methodology for low load-bearing capacity clay soils in the abutments of a 16-meter span beam bridge. To determine the load capacity in the geotechnical design, three calculation methods are used: the Federal Highway Administration (FHWA) methodology, the Spanish Guide for Projects and the Execution of Micropiles in Road Works, and the method proposed by Bustamante and Doix in 1985. Additionally, the verification of compression, tension, and shear of the micropiles under the acting stresses in the ultimate limit states of the bridge’s structural design is carried out, according to the Technical File with CUI No. 2535402.The cost and benefit of the solution employed by the contractors, which involves the replacement with granular soils and false footings along with the implementation of fiber-reinforced polymer micropiles, are also evaluated through the unit cost analysis with the S10 Program. The allowable load capacity (Qadm) with the micropile foundation reaches 34.61 kg/cm². In the design of the deep foundation for the abutments of the Paccho Molinos Bridge in Huancavelica, the use of 9 micropiles with a diameter of 20 cm and a depth of 6 meters in each abutment is necessary to ensure structural resistance to compression, tension, and shear.Finally, the use of micropiles as a deep foundation reduces the investment cost by 45.80% compared to the soil replacement technique with false footings.
