Abstract:

This paper describes an ongoing study where aggregate layer modulus enhancement due to geo-synthetic stabilization was quantified via shear wave measurements using bender element (BE) sensor technol-ogy in both laboratory triaxial test setup and a large-scale testbed. Five different integral geogrids, two welded geogrids, one woven geogrid, one woven geotextile and one nonwoven geotextile were evaluated in repeated load triaxial testing. Some of the geosynthetics with good performance trends were also evaluated in a large-scale testbed. Both modulus enhancement and extent of geosynthetic influence zone were quantified. The results herein provide quantitative inputs to include geosynthetics into mechanistic-empirical pavement design.
