Ezikhathini zamuva nje, izinhlangano zikaloliwe emhlabeni wonke ziye zaphendukela ekusebenziseni i-geosynthetics njengesixazululo esinezindleko eziphansi sokuzinzisa i-ballast.Kulo mbono, ucwaningo olubanzi lwenziwe emhlabeni wonke ukuhlola ukusebenza kwe-ballast eqiniswe yi-geosynthetic ngaphansi kwezimo ezihlukahlukene zokulayisha.Leli phepha lihlola izinzuzo ezihlukahlukene imboni yezitimela engazithola ngenxa yokuqiniswa kwe-geosynthetic.Ukubuyekezwa kwezincwadi kuveza ukuthi i-geogrid ibopha ukusabalala kwe-ballast ehlangothini, inciphisa izinga lokuhlala mpo unomphela futhi inciphise ukuphuka kwezinhlayiyana.I-geogrid iphinde yatholakala ukunciphisa izinga lokucindezelwa kwe-volumetric ku-ballast.Ukuthuthukiswa kokusebenza sekukonke ngenxa ye-geogrid kubonwe njengomsebenzi wesici esibonakalayo esisebenza kahle (φ).Ngaphezu kwalokho, ucwaningo luphinde lwasungula indima eyengeziwe yama-geogrids ekwehliseni ukuhlaliswa kwethrekhi okuhlukile kanye nokunciphisa izingcindezi ezingeni le-subgrade.I-geosynthetics itholwe inenzuzo enkulu uma amathrekhi ahlala kuma-subgrades athambile.Ngaphezu kwalokho, izinzuzo ze-geosynthetics ekuqiniseni i-ballast zitholwe ziphakeme kakhulu uma zibekwe ngaphakathi kwe-ballast.Indawo ekahle yokubeka ye-geosynthetics ibikwe abacwaningi abaningana ukuthi icishe ibe ngu-200-250 mm ngaphansi kwe-slee soffit yokushona okujwayelekile kwe-ballast okungu-300-350 mm.Uphenyo oluningi lwezikimu kanye nezikimu zokuvuselela umkhondo kuphinde kwaqinisekisa indima ye-geosynthetics/geogrids ekuqiniseni amathrekhi ngaleyo ndlela kusize ekususeni imikhawulo eqinile yesivinini ebibekwe ngaphambili, kanye nokuthuthukisa isikhawu sesikhathi phakathi kokusebenza kokulungisa.
