Feasibility of the Use of Existing Analytical Models and Experimental Data toAssess Current Design Methods for Pavement Geogrid-Reinforced Base Layers

摘要

In recent years polymer geogrids have been proposed and used to improve theperformance of paved roadways and/or to reduce base course thickness. Performance improvements have been demonstrated for design conditions where relatively large rut depths are acceptable and where relatively weak pavement sections have been used. This work was undertaken to examine existing literature concerning laboratory and field experimental studies, and analytical studies pertaining to inclusion of geogrid polymer materials in roadway pavement sections for the purpose of improving performance or to allow for a reduction in the constructed section thicknesses.
