Munguva pfupi yapfuura, masangano echitima pasirese akashandisa geosynthetics semhinduro inodhura yekudzikamisa ballast. Mune maonero aya, zvidzidzo zvakakura zvakaitwa pasi rose kuti zviongorore kushanda kwegeosynthetic-reinforced ballast pasi pemamiriro akasiyana-siyana ekurodha. Iri bepa rinoongorora mabhenefiti akasiyana siyana anogona kuwanikwa neindasitiri yechitima nekuda kweiyo geosynthetic kusimbiswa. Ongororo yezvinyorwa inoratidza kuti geogrid inosunga kupararira kwekupedzisira kweballast, inoderedza huwandu hwekugara yakamira yakamira uye inoderedza kutsemuka kwechikamu. Iyo geogrid yakawanikwa zvakare kuderedza kuwanda kweiyo volumetric compression muballast. Kuvandudzwa kwekuita kwese kwese nekuda kwegeogrid kwakaonekwa kuve basa reiyo interface inoshanda factor (φ). Zvakare, zvidzidzo zvakare zvakasimbisa iro rekuwedzera basa rema geogrids mukudzikisa mutsauko wekugara uye kuderedza kushushikana padanho repasi. Iyo geosynthetics yakawanikwa ichinyanya kubatsira kana ma track achizorora pane akapfava subgrades. Uyezve, mabhenefiti e geosynthetics mukudzikamisa ballast akawanikwa ari akanyanya kukwirira kana akaiswa mukati me ballast. Iyo yakakwana yekuisa nzvimbo ye geosynthetics yakashumwa nevaongorori vakati kuti ingangoita 200-250 mm pazasi pesofit yekurara yeyakajairwa ballast kudzika kwe300-350 mm. Huwandu hwekuferefeta kwemumunda uye zvirongwa zvekudzoreredza track zvakasimbisawo basa re geosynthetics/geogrids mukudzikamisa matinji nekudaro zvichibatsira mukubvisa zvirambidzo zvekumhanya zvakatemerwa kare, uye kusimudzira nguva pakati pekugadzirisa mabasa.
