3. Amfani da geogrid tare da zare na asali
Geogrid wajen amfani da manyan abubuwan da suka shafi ƙarfi, juriyar tsagewa, da kuma haɗakar ƙasa, juriya da tattalin arzikinta. A halin yanzu, ana amfani da geogrid a fannin gadon hanya, gadon layin dogo, magudanar ƙasa, haɓaka gangaren banki, tallafi da riƙe tsari, gyaran layin karyewar dutse, gyaran haɓaka shimfidar ƙasa da hana tsagewar haske da kuma kula da shi. Musamman amfani da geogrid a cikin haɓaka shimfidar ƙasa da hana tsagewar haske. Tsagewar haske shine matakin ciyawar hanya saboda canjin zafin jiki ko ɗaukar kaya da yawa kuma yana haifar da tsagewa, kuma ta hanyar yaduwar damuwa tsakanin layuka zuwa saman hanya, yana haifar da motsi a tsaye ko a kwance tsakanin layuka kuma yana sa farfajiyar hanya ta fashe. Amfani da geogrid mai aiki mai kyau zai iya inganta ƙarfin yanke layin da kuma aikin gajiya mai lanƙwasa na hanya yadda ya kamata, yana wargaza yawan damuwa, don haka yana hana faruwar tsagewar shimfidar ƙasa yadda ya kamata, kuma yana rage farashin kula da hanya sosai. Tsagewar tunani wani abu ne da aka saba samu a shimfidar ƙasa. Don tsagewar haske a saman hanya, sanya layin geotextile tsakanin layin saman kwalta da rufin ƙasa na iya kawar ko rage samar da tsagewar haske a cikin layin saman, don haka tsawaita rayuwar sabis na titin. Amma yanayin zafin da ke zuba a kan titin kwalta har zuwa 160 ℃, wanda ke haifar da ninka geotextile ko polymer geogrid, lalacewa, laushi, don haka aikin sa ya ragu sosai. Ana amfani da shi a kan titin kwalta geogrid ya fi kyau a yi amfani da geogrid na basalt fiber, saboda geogrid na basalt fiber yana da juriya mai kyau ga zafi, da ƙarfi mai yawa, babban modulus, ƙarancin tsayi, ƙarancin coefficient na faɗaɗa zafi da sauran halaye.
