1. Nkọwa nke eriri basalt geogrid
Basalt geogrid A na-ahọrọ eriri eriri basalt, iji igwe akwa ákwà ogologo mba ọzọ nke a kpara n'ime ihe mkpuchi ahụ, iji usoro nhazi nke ịkpa ákwà warp, jiri ákwà ahụ mee ihe nke ọma n'ike eriri ahụ, iji melite ihe onwunwe ya, ka o wee nwee ike ịdọkpụ dị mma, ike ndọda na iguzogide ịrị elu, na mgbe ejiri netwọk ihe dị elu kpuchie asfalt ahụ. Ọ na-agbaso ụkpụrụ nke ndakọrịta yiri nke ahụ, na-elekwasị anya na arụmọrụ ya na ngwakọta asfalt, ma na-echebe ihe mkpuchi eriri ahụ nke ọma, na-eme ka iguzogide abrasion na iguzogide shear nke ihe mkpuchi ahụ ka mma nke ukwuu, ka e wee jiri ya mee ka pavement dịkwuo mma, iguzogide mgbawa mgbawa na ihe egwu okporo ụzọ ndị ọzọ, na ịkwụsị pavement asfalt ahụ siri ike ime ka nsogbu ahụ ka njọ.

Ngwaahịa a nwere uru dị na ya Ike Dị Elu, obere ogologo, oke okpomọkụ na-eguzogide, modulus dị elu, ibu dị mfe, ezigbo ike, iguzogide nchara, ogologo ndụ ọrụ, dị mfe itinye, wdg., enwere ike iji ya mee ihe n'ọtụtụ ebe na simenti ochie, mmezi ụzọ ụgbọ elu, embankment, ụsọ osimiri, nchedo mkpọda, ọgwụgwọ mmezi ụzọ na akwa mmiri na mpaghara injinia ndị ọzọ, nwere ike inye pavement ahụ iji mee ka nkwado ahụ dịkwuo mma, mee ka ọ sie ike, iji gbochie mgbawa ike ọgwụgwụ na pavement, mgbasawanye okpomọkụ na oyi na mgbawa mkpụmkpụ na mgbawa na-esote, ọ nwekwara ike ịgbasa nrụgide na-ebu pavement ma mee ka ndụ ọrụ nke pavement ahụ dị ogologo.
Ike nrụgide dị elu na ogologo dị ala: eriri basalt geogrid dabere na eriri basalt dị ka ihe eji arụ ọrụ, ike nrụgide eriri basalt dịkwa elu nke ukwuu, karịa eriri ndị ọzọ na ígwè nkịtị. N'otu oge ahụ, ọ nwere modulus dị elu, nwere nnukwu iguzogide mgbanwe, ogologo mgbawa erughị 3%.
Enweghị ihe na-agbagharị ogologo oge: dịka ihe na-eme ka ihe sie ike, yana ikike iguzogide mgbanwe n'ihe gbasara ibu ogologo oge nke iguzogide ihe na-agbagharị dị oke mkpa, eriri basalt agaghị agbagharị, iji hụ na ngwaahịa ahụ nwere ike ịnọgide na-arụ ọrụ ogologo oge.
Ezigbo nkwụsi ike anụ ahụ na kemịkalụ: eriri basalt n'onwe ya nwere ike iguzogide nrụrụ acid na alkali siri ike, basalt geogrid nwere ike iguzogide ọtụtụ mmebi anụ ahụ na mbibi kemịkalụ, kamakwa megide mbuze ndụ na mgbanwe ihu igwe, iji hụ na arụmọrụ ya agaghị efu.
Ezigbo nkwụsi ike okpomọkụ: ebe agbaze eriri basalt na 1500 ° C ma ọ bụ karịa, ojiji ogologo oge nke okpomọkụ dị n'etiti -260 ° ~ 650 °, iji hụ na basalt geogrid n'ọrụ imepe ụzọ iji nagide ọnọdụ okpomọkụ dị elu.
Nchịkọta nke mkpọchi na mmachi agbakwunyere: n'ihi na basalt geogrid bụ nhazi mesh, enwere ike ịbanye na simenti asfalt n'ime mkpokọta ahụ, ka e wee nwee ike ịmepụta mkpọchi igwe ejiri mee ihe. Mmachi a na-egbochi mmegharị nke mkpokọta ahụ, ka ngwakọta asfalt ahụ wee nwee ike nweta ọnọdụ mkpokọta ka mma, ikike ibu ibu dị elu, arụmọrụ mbufe ibu ka mma na obere mgbanwe.
Ndakọrịta na ngwakọta asphalt: basalt geogrid n'oge usoro ọgwụgwọ mgbe emechara ya, e mere ihe ndị a kpuchiri ekpuchi maka ngwakọta asphalt, eriri ọ bụla ejiri asphalt kpuchie ya nke ọma nwere oke nkwekọ, si otú a na-ahụ na eriri basalt geogrid dị na oyi akwa asphalt agaghị ekewapụ ya na ngwakọta asphalt ahụ, kama ọ ga-ejikọta ya nke ọma.
Mgbochi ike ọgwụgwụ: basalt geogrid dị na oyi akwa elu asphalt, nwere ike ịbụ nrụgide wiil n'elu elu okporo ụzọ na mgbasa nrụgide na nrụgide nke na-esi na ya apụta, nhazi mpaghara nchekwa n'etiti mpaghara nrụgide abụọ ahụ, mgbanwe nrụgide nwayọ nwayọ kama mgbanwe mberede, na-ebelata mgbanwe mberede nke nrụgide na oyi akwa elu asphalt nke mmebi. N'otu oge ahụ, obere ịgbatị nke basalt geogrid na-ebelata mgbagọ nke pavement, na-eme ka pavement ahụ ghara ịpụta oke mgbanwe.
Rutting na-eguzogide okpomọkụ dị elu: ojiji nke basalt geogrid na oyi akwa asphalt, nke na-arụ ọrụ ọkpụkpụ na oyi akwa asphalt. Gbakọta na simenti asphalt site na grid, na-emepụta usoro mkpọchi igwe mejupụtara, na-egbochi mmegharị nke ihe ndị aggregates, na-amụba ike njikọ transverse na oyi akwa elu asphalt, oyi akwa elu asphalt nke akụkụ ọ bụla nke ibe ya, na-egbochi oyi akwa elu asphalt nke push iji rụọ ọrụ nke iguzogide rutting.
Mgbochi mbelata okpomọkụ dị ala: n'ọnọdụ okpomọkụ dị ala, mbelata oyi nke simenti asphalt, nke na-ebute nrụgide nrụgide, mgbe nrụgide nrụgide karịrị ike nrụgide nke simenti asphalt, na-ebute mgbawa. Basalt geogrid n'iji akwa elu asphalt eme ihe, na-eme ka oyi akwa elu nke ike nrụgide transverse dịkwuo mma, ka ike nrụgide nke simenti asphalt dịkwuo mma nke ukwuu, nwere ike iguzogide nrụgide nrụgide buru ibu na-enweghị mmebi. Na mgbakwunye, ọbụlagodi na n'ihi mpaghara mpaghara nke mgbawa, na mgbawa ndị na-eme nrụgide nrụgide, site na mbufe geogrid basalt ma pụọ, mgbawa agaghị aghọ mgbawa.
Mbelata nke mgbawa ndị na-egosipụta ihe n'oge na-adịghị anya: na asphalt nwere basalt geogrid flat layer, gbochie nrụgide shear ma ọ bụ tensile nke ibu okporo ụzọ na-akpata, hapụ nrụgide ahụ, dị ka ihe nkwado asphalt simentị, iji mezuo ebumnuche nke igbu oge mbelata mgbawa.

3. Ngwa nke geogrid na eriri bụ isi
Geogrid n'itinye ihe ndị bụ isi n'ọrụ dịka ike, mgbochi ịdọka, na njikọta nke ala, ogologo oge na akụnụba ya. Ugbu a, ejirila geogrid mee ihe n'ọhịa okporo ụzọ, ala ụgbọ okporo ígwè, ihe mgbochi ala, mmụba ugwu, nkwado na idobe usoro, ndozi oyi akwa mgbawa nkume, ndozi mmezi pavement na mgbochi mgbawa ntụgharị uche. Karịsịa itinye geogrid n'ọrụ mmezi pavement na mgbochi mgbawa ntụgharị uche. Mgbawa ntụgharị uche bụ ọkwa mgbọrọgwụ okporo ụzọ n'ihi mgbanwe okpomọkụ ma ọ bụ ibu buru ibu ma mepụta mgbawa, site na mgbasa nrụgide interlayer gaa n'elu okporo ụzọ, mepụta mmegharị kwụ ọtọ ma ọ bụ kwụ ọtọ n'etiti oyi akwa ma mee ka elu okporo ụzọ gbawaa. Itinye geogrid arụmọrụ dị elu nwere ike imeziwanye ike shear interlayer na arụmọrụ ike ọgwụgwụ nke okporo ụzọ nke ọma, na-agbasa mkpokọta nrụgide, si otú a na-egbochi mmepe nke mgbawa pavement, ma belata ọnụ ahịa mmezi okporo ụzọ nke ukwuu. Mgbawa ntụgharị uche bụ ihe a na-ahụkarị na pavement asphalt. Maka mgbawa ntụgharị uche n'elu okporo ụzọ, itinye akwa geotextile n'etiti oyi akwa elu asphalt na ihe mkpuchi nwere ike iwepụ ma ọ bụ belata mmepụta nke mgbawa ntụgharị uche na oyi akwa elu, si otú a na-agbatị ndụ ọrụ nke okporo ụzọ ahụ. Mana okpomọkụ nke pavement asphalt ruo 160 ℃, na-ebute geotextile ma ọ bụ polymer geogrid fold, deformation, slowing, ka arụmọrụ ya wee belata nke ukwuu. Ejiri ya na pavement asphalt, geogrid kacha mma iji basalt fiber geogrid, n'ihi na basalt fiber geogrid nwere ezigbo iguzogide okpomọkụ, yana ike dị elu, modulus dị elu, obere elongation, obere coefficient nke mgbasawanye okpomọkụ na njirimara ndị ọzọ.
