The traffic of vehicles on the surface of roads yield deformations in the pavement structure that are a function of both the traveling loads and the mechanical characteristics of the pavement itself. These deformations are either reversible (elastic deflections) or permanent (plastic ruts). With the cyclic application of traffic load, these deformations degrade the pavements and irregularities, ruts, longitudinal asphalt cracks, and alligator cracks appear on the surface. The structural strength of flexible pavement is related to its constitutive elements: the asphalt layer, the granular base, the in-situ subgrade soil and the geosynthetic reinforcement. Geosynthetics are, nowadays, commonly used in flexible road base reinforcement by inserting them typically at the interface between the aggregate base course and the subgrade. The aim of this in-ground test is to quantify and evaluate the structural contribution of geosynthetic reinforcement to pavement systems and to develop a sound design algorithm based upon actual empirical testing of geogrid reinforced road sections.
