• Ngwaahịa nwere uru nke Ike dị elu, ala elongation, elu okpomọkụ na-eguzogide, elu modulus, ìhè arọ, ezi siri ike, corrosion eguzogide, ogologo ọrụ ndụ, mfe dabara, wdg, nwere ike ọtụtụ-eji na ochie ciment pavement, ọdụ ụgbọ elu runway mmezi, embankment, osimiri bank, mkpọda nchebe, okporo ụzọ na àkwà mmiri pavement nkwalite ọgwụgwọ na ndị ọzọ engineering ubi, nwere ike inye pavement iji welie na okpomọkụ na-emesi ike, ike ọgwụgwụ na-eme ka ike ọgwụgwụ na-eme ka okpomọkụ na-eme ka aru ike, na-eme ka ike ọgwụgwụ na-eme ka ike ọgwụgwụ, na-eme ka okpomọkụ na-eme ka ọ dịkwuo elu, na-eme ka ike ọgwụgwụ na-eme ka ike sie ike na pavement. mgbasawanye na mgbawa mgbawa na mgbawa na-atụgharị anya na-esote, na Ọ nwere ike ịgbasa pavement na-enwe nrụgide na ogologo ndụ ọrụ nke pavement.
• Ike ike dị elu na elongation dị ala: basalt fiber geogrid dabeere na eriri basalt dị ka ihe ọkụkụ, na basalt fiber tensile ike dị oke elu, karịa eriri ndị ọzọ na ígwè nkịtị. N'otu oge ahụ ọ nwere modul dị elu, nwere nnukwu iguzogide deformation, mgbaji elongation bụ ihe na-erughị 3%.
• Ọ dịghị ogologo oge na-akpụ akpụ: dị ka ihe na-agba ume, na-enwe ike iguzogide nrụrụ n'ihe banyere ibu ogologo oge nke na-eguzogide ihe na-akpụ akpụ dị oke mkpa, eriri basalt agaghị abanye, iji hụ na ngwaahịa ahụ nwere ike ịnọgide na-arụ ọrụ ogologo oge.
• Nkwụsi ike nke anụ ahụ na nke kemịkal dị mma: eriri basalt n'onwe ya nwere nguzogide siri ike na acid na alkali corrosion, basalt geogrid nwere ike iguzogide ụdị anụ ahụ dị iche iche na nsị kemịkalụ, kamakwa megide mmebi nke ndu na mgbanwe ihu igwe, iji hụ na arụmọrụ ya adịghị efu.
• Ezi nkwụsi ike nke okpomọkụ: ebe mgbaze basalt fiber na 1500 Celsius C ma ọ bụ karịa, ogologo oge iji okpomọkụ n'etiti -260 ° ~ 650 Celsius, iji hụ na basalt geogrid na paving ọrụ na-eguzogide elu okpomọkụ kwụsie ike.
• Mkpokọta nke agbakwunyere mkpọchi na mmachi: n'ihi na basalt geogrid bụ ntupu Ọdịdị, asphalt ihe na mkpokọta nwere ike penetrated, nke mere na e guzobere n'ibu agbakwunyere mkpọchi. Mgbochi a na-egbochi mmegharị nke mkpokọta, nke mere na ngwakọta asphalt n'ihe banyere ibu nwere ike nweta ọnọdụ dị mma nke mgbagwoju anya, ikike ibu ibu dị elu, ọrụ nnyefe dị mma na obere nrụrụ.
• Na ngwakọta ngwakọta asphalt: basalt geogrid na usoro ọgwụgwọ post-ọgwụgwọ ihe eji eme ihe maka ngwakọta asphalt, eriri ọ bụla ejiri asphalt kpuchie ya nke ọma nwere oke ndakọrịta, si otú a na-ahụ na basalt fiber geogrid na oyi akwa asphalt agaghị ekewapụ ya na ngwakọta asphalt, mana jikọtara ọnụ.
• Mgbochi ike ọgwụgwụ: basalt geogrid na akwa akwa akwa akwa, nwere ike ịbụ nrụgide wheel n'elu okporo ụzọ na ihe na-akpata mkpakọ na nrụgide nrụgide na-akpata, nhazi nke mpaghara nchekwa n'etiti mpaghara nchekasị abụọ, mgbanwe nke nwayọọ nwayọọ karịa mgbanwe mberede, na-ebelata mgbanwe mberede nke nrụgide n'elu oyi akwa nke asphalt. N'otu oge ahụ, elongation dị ala nke basalt geogrid na-ebelata nkwụsị nke pavement, na-ahụ na pavement agaghị eme oke nrụrụ.
• Rutting na-eguzogide okpomọkụ dị elu: ojiji nke basalt geogrid na oyi akwa asphalt, nke na-arụ ọrụ ọkpụkpụ na oyi akwa asphalt. Mkpokọta na asphalt ihe site okporo, na-akpụ a mejupụtara n'ibu kpochidoro usoro, ịmachi ije nke aggregates, na-amụba transverse adịgide adịgide ike na asphalt elu oyi akwa, asphalt elu oyi akwa nke ọ bụla akụkụ nke ọ bụla ọzọ, igbochi asphalt elu oyi akwa nke push na-egwu ọrụ nke iguzogide rutting.
• Mgbochi dị ala okpomọkụ shrinkage cracking: na obere okpomọkụ ọnọdụ, asphalt ihe oyi shrinkage, na-akpata nrụgide tensile, mgbe tensile nrụgide karịrị tensile ike nke asphalt kompat, butere cracks. Basalt geogrid na ngwa nke akwa oyi akwa asphalt, na-emeziwanye elu elu nke ike ike nke transverse, nke mere na ike ike nke asphalt dị mma nke ukwuu, nwere ike iguzogide nrụgide siri ike na-enweghị mmebi. Tụkwasị na nke ahụ, ọ bụrụgodị na n'ihi mpaghara mpaghara nke mgbawa, na mgbawa na-eme ka nrụgide nrụgide, site na basalt geogrid na-ebufe ma na-apụ n'anya, mgbawa agaghị etolite n'ime mgbawa.
• Mbelata nke mgbawa na-egbuke egbuke: na asphalt na basalt geogrid flat Layer, na-egbochi ịkwa ahụ ma ọ bụ nrụgide na-akpata site na ibu okporo ụzọ, hapụ ihe mgbagwoju anya, dị ka ihe mgbakwasị ụkwụ nke asphalt, iji nweta nzube nke igbu oge nkwụsị nke cracks.

3.The ngwa nke geogrid na isi eriri
Geogrid na ntinye nke isi echiche nke ike, nkwụsị anya mmiri, na nchikota nke ala, ogologo oge na akụ na ụba ya. Ka ọ dị ugbu a, a na-eji geogrid na mpaghara okporo ụzọ awara awara, okporo ụzọ ụgbọ okporo ígwè, mkpọda ala, nkwalite mkpọda ụlọ akụ, nkwado na njide ihe owuwu, nrụzi akwa akwa nkume mgbaji, ndozi pavement na mgbochi mgbawa na-atụgharị uche. Karịsịa ngwa nke geogrid na nkwalite pavement na mgbochi nke mgbawa ntụgharị uche. Ntụgharị mgbawa bụ larịị ahịhịa-mgbọrọgwụ okporo ụzọ n'ihi mgbanwe okpomọkụ ma ọ bụ ibu ibu nke ukwuu ma na-emepụta mgbawa, na site na nrụgide interlayer na-agbasa n'elu okporo ụzọ, na-emepụta mmegharị kwụ ọtọ ma ọ bụ kwụ ọtọ n'etiti ọkwa ma na-eme ka elu ụzọ ahụ gbawaa. Ngwa nke geogrid na-arụ ọrụ dị elu nwere ike imeziwanye ike nkesa interlayer na ịgbado ike ọgwụgwụ nke okporo ụzọ, na-agbasa nrụgide nrụgide, si otú a na-egbochi ihe omume nke pavement gbawara agbawa nke ọma, ma belata ọnụ ahịa nlekọta okporo ụzọ. Ntụgharị uche bụ ihe a na-ahụkarị na pavement asphalt. Maka ntụgharị uche na-agbawa n'elu okporo ụzọ, ịtinye akwa geotextile n'etiti oyi akwa nke asphalt na ihe dị n'okpuru ebe a nwere ike iwepụ ma ọ bụ mee ka ọgbọ nke ntụgharị uche dị n'elu oyi akwa, si otú ahụ na-agbatị ndụ ọrụ nke okporo ụzọ. Ma pavement asphalt na-awụsa okpomọkụ ruo 160 ℃, na-akpata geotextile ma ọ bụ polymer geogrid fold, deformation, softening, nke mere na arụmọrụ ya na-ebelata nke ukwuu. Etinyere na asphalt pavement geogrid kasị mma iji basalt fiber geogrid, n'ihi na basalt fiber geogrid nwere ezigbo okpomọkụ na-eguzogide, na ike dị elu, elu modulus, ala elongation, ala ọnụọgụ nke mgbasawanye thermal na àgwà ndị ọzọ.
