Did not investigate ideas to improve material genesis. Add Dynamic Cone Penetrometer (DCP) and Light Weight Deflectometer (LWD) probes. Add typical roadway model, used to map out the modulus-porosity-grid-grain shape relationship. Enhance hill material to include general grain shapes via clumped grains. Add Multiple Aperture Tensile (MAT) grid test. Properties to match Tensar SS20 Single Rib Tensile (SRT) and Aperture Grids, add ability to create triaxial beamed grids, and determine grid Enhance geogrid representation via beamed Structural beam of rectangular cross section with properties of Young's Of spherical balls joined by beamed contacts provides the behavior of a Create beam contact model, and verify that a string Extend the geogrid representation to allow different geogrid.

The PFC3D code can be obtained HERE, and the pavement-design package is provided below. FISH is a programming language embedded within PFC3D. * [The pavement-design package is provided in the form of a consistent set of FISH functions that operate within PFC3D version 5.0. 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.
