Investigate the behavior of other aggregate-geogrid systems such as a Grain-size distribution, initial specimen porosity, moisture content andĬonfining stress are varied (Potyondy et al., 2016 Siekmeier et al.,Ģ016 Siekmeier and Casanova, 2016). Geogrid-reinforced aggregate roadway configurations in which the Modulus of the aggregate base without geogrid) for typical Resilient modulus of the aggregate base with geogrid to resilient
Minnesota by estimating geogrid gain factors (defined as the ratio of Package is being used to improve pavement-design methodology in Geometry, structural stiffness and grid-grain interface behavior. The microstructural properties of the geogrid include: Grains, grain material type, moisture content and initial specimen Material include: grain size distribution of spherical or clumped
The microstructural properties of the granular Macroscopic response, which includes the stress-strain curves producedĭuring triaxial tests. Study and quantify the effect of microstructural properties on Restraint to the granular material as a result of interlocking andįriction between the geogrid and the granular material, and this isīelieved to be the primary structural benefit of adding geogrid to theĪggregate base layer of a pavement structure. Granular material containing geogrid.* The geogrid provides lateral Supports creation and triaxial testing of a synthetic unsaturated The pavement-design package (Potyondy, 2019) for the Particle Flow Code in 3 Dimensions ( PFC3D)
