Abstract This paper illustrates application of a locally produced geogrid material for strength improvement expansive subgrade soil. Samples black, soft soil predominating the study area were collected from south western parts Modjo town, inside rift valley region central Ethiopia. X-Ray diffraction as well index property tests executed to identify and categorize expansiveness highly plastic Th...

The development of reinforcements for soil has made an impact in most the civil engineering sectors especially transportation. use geogrids is frequent roadways but they are also finding railways. major that could have providing desired stiffness to a section by reducing material and serving as proper reinforcement material. In current study, attempt been redesign railway embankment economicall...

Geosynthetics (GSN) are polymeric products used in Geotechnical Engineering for the purpose of improving properties insitu soil. In this project, experimental work was carried out to determine influence presence fines within granular soil on CBR strength reinforced with different GSN (Woven geotextile, Non-woven Geogrid and Geonet). Two types disturbed state containing varying percentage were s...
