To access a residential complex located in the Northwest sector of Punta Arenas, it was necessary to traverse terrain composed of compressible soils with very low bearing capacity (locally known as “mazacote” [9] and peat [2][5]).

For the construction of the roadway, the proposed solution was a reinforced embankment using Biaxial Geogrids. A stability analysis was carried out, and a simplified geotechnical model was developed to estimate the expected theoretical settlement.

Additionally, to accelerate the consolidation process, a pre-load was applied, consisting of a stabilized granular base, which would later serve as the riding surface. Topographic readings were taken on the embankment surface and its performance was monitored over time.

Once the vertical movements of the embankment had ceased, the pre-load was removed, and the pavement project was implemented, achieving the required factor of safety to ensure proper performance and durability according to the proposed design.
