COMPACTION OF GRANULAR MATERIALS MADE FROM RECYCLED GLASS BOTTLES COMBINED WITH GEOGRIDS

Abstract

In order to evaluate the effects of geogrids in improving the compactibility of poorly compactible granular materials made from recycled glass bottles, compaction tests were conducted. They revealed that geogrid was effective in improving the compactibility. Moreover, in order to evaluate the effects of geogrids in improving the deformation and strength properties, triaxial tests were conducted on this material compacted with geogrids. They revealed that residual strain after cyclic loading could be reduced by using geogrids. However, small strain stiffness during cyclic loading did not change significantly. On the other hand, the peak strength under monotonic loading could be improved by using geogrids.
