Abstract:

In this study, the behavior of two biaxial geogrids and a reinforcing geotextile located at different depths in a subbase layer of a pavement, composed of light tezontle, is evaluated through a standard static load test.

The load tests were carried out inside a test box of dimensions 2.0 x 2.0 x 1.50m. The sensors used for the study included linear transducers of variable displacement, pressure and load cells, and strain gauges attached to the geosynthetics.

Additionally, numerical modeling with finite elements was carried out using PLAXIS 3D Software in order to compare the results with those obtained experimentally and to identify their prediction capacity.
