Unpaved Road Stabilization Using Bamboo Grid and Bitumen Coated Bamboo Cells

Abstract

The present study encompasses laboratory model tests, both static and cyclic loading, on fly ash sub-bases of varying thickness overlying sand subgrade. Different sub-base conditions were created by introducing a single basal bamboo geogrid beneath the sub-base as well as reinforcing the sub-base with bamboo geocell without and with single basal bamboo geogrid. The cyclic load tests indicated considerable reduction in cyclic and permanent deformations in reinforced models as compared to unreinforced models; around 44% reduction in cyclic deformation and 35% reduction in permanent deformation were achieved for fly ash sub-base reinforced with bamboo geocell mattress with single basal bamboo geogrid.
