Sezvo pamusoro pesimbi-plastiki geogrid inosvika pakuita yakakasharara pateni, inoiswa pasi pekunetseka kwakanyanya uye kupokana nekuzadza, izvo zvinomisa kuveura, kudzvanya kwepashure uye kusimudzwa kwenheyo ivhu zvakazara. Pamusana pekuoma kwepamusoro kwesimbi yakasimbiswa yevhu, inobatsira kupararira uye kutakura yunifomu yemutoro wepamusoro wenheyo, uye inogoverwa pamusoro pevhu rakapfava revhu rine simba rakanaka rekutakura. Saka, chii chiri kushandiswa kwesimbi epurasitiki geogrids pane asphalt overlays?
Pamusana pekushanda kwayo kwakanakisisa, mushure mekugadzirisa kwepamusoro uye kugadziriswa kwekuvhara, nzvimbo dzepamusoro dzesimbi nepurasitiki dzakashanduka, zvinhu zvakasanganiswa zvesimbi zvakagadziridzwa, uye kupikisa kupfeka uye kupikisa kweshear kwematrix kwakagadziridzwa zvikuru.vandudza. Iyo simbi yepurasitiki geogrid inogadzirwa nesimbi yepurasitiki geogrid inogadzira inogona kuita basa rakakosha kana yaiswa kune asphalt yakavharika.
Kana kutonhora kwakakwirira, pamusoro peasphalt pavement yakapfava uye inonamira; pasi pechiito chemutoro wemotokari, nzvimbo yeasphalt haigoni kudzokera kune yayo yapfuura. Mushure mokunge mutoro wacho wabviswa, deformation yeplastiki inoitika. Plastic deformation inoumbwa pasi pesimba rekugara kuunganidza uye kudzokororwa kutenderera kwemotokari panguva yeestrus. Mune asphalt pavement, simbi yepurasitiki geogrid inogona kuparadzira kushushikana uye kusagadzikana kunetseka, uye kugadzira nzvimbo yebuffer pakati pezviviri izvi. Kushungurudzika hakusi kuchinjwa kamwe kamwe asi zvishoma nezvishoma, izvo zvinoderedza kukanganisa kweasphalt pavement inokonzerwa nekushanduka kamwe kamwe kwekunetseka. Panguva imwecheteyo, kureba kwakadzika kunoderedza kutsauka kwepamusoro pemugwagwa uye kunovimbisa kuti mugwagwa hauzoitirwe deformation yakawandisa.
Simbi plastiki geogrid chinhu chikuru geosynthetic zvinhu. Iyo ine yakasarudzika zvivakwa uye inoshanda ichienzaniswa nemamwe geosynthetics. Geogrids inowanzoshandiswa pakusimbisa zvivakwa zvevhu zvakasimbiswa kana zvinhu zvinosanganiswa. Iyo simbi-yepurasitiki geogrid yakagadzirwa nepamusoro-simba simbi waya kuburikidza nekurapa kwakakosha, uye inokwidziridzwa mumubatanidzwa wepamusoro-simba resimbi bhandi rine rough embossing pamusoro pezvinowedzera senge polyethylene kana polypropylene. Iri bhandi rimwe chete rakarukwa kana kusungirirwa pane imwe chinhambwe kureba uye kuchinjika, uye majoini aro akaiswa welded nehunyanzvi hwekusimbisa uye bonding welding tekinoroji. Iyo yakasimbiswa geogrid.
