In this paper,the mechanisms of High density polyethylene( HDPE) geogrids after photo-oxidation ag-ing are introduced systematically. Analyzed the influence factors for geogrids during photo-oxidation degradation,in-cluding environment factors,installation damages and processing methods. Simultaneously,introduced performance changes in the photo-oxidation of high density polyethylene geogrids,and summarized characterization of indicators from the mechanical properties,changes in appearance and microstructure indicators. Also pointed out deficiency at aspects of research and future research issues are analyzed for HDPE geogrids.
