Morao tjena, mekhatlo ea literene ho pota lefatše e sebelisitse tšebeliso ea geosynthetics e le tharollo e theko e tlaase ea ho tsitsisa ballast. Ka pono ena, ho entsoe liphuputso tse batsi lefatšeng ka bophara ho lekola ts'ebetso ea "geosynthetic-reinforced ballast" tlasa maemo a fapaneng a ho jarolla. Pampiri ena e lekola melemo e fapaneng eo indasteri ea literene e ka e fumanang ka lebaka la matlafatso ea geosynthetic. Tlhahlobo ea lingoliloeng e senola hore geogrid e ts'oara ho ata ha ballast ka morao, e fokotsa boholo ba sebaka sa ho lula se otlolohileng mme e fokotsa ho robeha ha likaroloana. Geogrid e ile ea boela ea fumanoa e fokotsa boholo ba likhatello tsa volumetric ho ballast. Kakaretso ea ntlafatso ea ts'ebetso ka lebaka la geogrid e ile ea bonoa e le ts'ebetso ea sebopeho se sebetsang hantle sa sebopeho (φ). Ho feta moo, liphuputso li boetse li thehile karolo ea tlatsetso ea li-geogrids ho fokotsa maemo a fapaneng le ho fokotsa khatello ea maikutlo maemong a tlase. Li-geosynthetics li fumanoe li le molemo haholo haeba lipina li lutse holim'a li-subgrades tse bonolo. Ho feta moo, melemo ea geosynthetics ea ho tsitsisa ballast e fumanoe e phahame haholo ha e behoa ka har'a ballast. Sebaka se nepahetseng sa sebaka sa geosynthetics se tlalehiloe ke bafuputsi ba 'maloa hore se ka ba 200-250 mm ka tlase ho soffit ea boroko bakeng sa botebo bo tloaelehileng ba ballast ba 300-350 mm. Liphuputso tse 'maloa tsa masimong le merero ea ntlafatso ea pina le tsona li netefalitse karolo ea geosynthetics/geogrids ho tsitsisa litsela ka hona ho thusa ho tlosa lithibelo tse thata tse neng li behiloe pejana, le ho matlafatsa nako ea nako lipakeng tsa ts'ebetso ea tokiso.
