Geogrid Reinforced Embankment Construction Technology

This study focused on construction technology of geogrid reinforced clayey soil embankment on common earth foundation. It is conducted according to a test road located in TongChuan, North-West China's ShaanXi province. Long term strain of geogrid in the embankment was researched. Technology of slope protection was also researched.Proper construction steps of geogrid reinforced embankment and geogrid overlapped are given. It is shown that the bruises of geogrid are decreased if sheep-foot roller is used when lay-down thickness deeper than 30cm. The deformation of geogrid mainly comes of construction. The infiltration of rainwater is disadvantage for the stabilization of geogrid reinforced embankment. Cement-soil is effective and economical as slope protection of geogrid reinforced embankment.
