Kenyelletso ea basalt fiber geogrids

1.Tlhaloso ea fiber ea basalt geogrid
Basalt geogrid E khethiloe lesela la basalt fiber, tšebeliso ea mochini o lohiloeng oa kantle ho naha o lohiloeng ka har'a substrate, ts'ebeliso ea sebopeho se otlolohileng sa warp, sebelisa lesela ka matla a khoele, ho ntlafatsa thepa ea lona ea mochini, e le hore e be le matla a matle a thata, matla a ho tabola le ho hanyetsa ho thella, 'me ka mor'a hore asphalt ea boleng bo holimo e koahetsoe ka marang-rang a marang-rang a thepa. E latela molao-motheo oa tumellano e ts'oanang, e lebisang tlhokomelo ho ts'ebetso ea eona e kopantsoeng le motsoako oa asphalt, le ho sireletsa ka ho feletseng fiber substrate, ho ntlafatsa haholo ho hanyetsa abrasion le ho hanyetsa ha shear ea substrate, e le hore e ka sebelisoa bakeng sa ntlafatso ea litsela, ho hanyetsa ho phunyeha ha marang-rang le likotsi tse ling tsa litsela, 'me ho felisa tsela ea asphalt ho thata ho ntlafatsa bothata.

2.Litšobotsi tsa fiber geogrid ea motheo

• Sehlahisoa se na le melemo ea Matla a Phahameng, elongation e tlase, mocheso o phahameng oa ho hanyetsa, modulus o phahameng, boima bo bobebe, boima bo botle, ho hanyetsa kutu, bophelo bo bolelele ba tšebeletso, ho le bonolo ho lekana, joalo-joalo, e ka sebelisoa ka mokhoa o pharaletseng sebakeng sa khale sa samente se katiloeng, tlhokomelo ea litsela tsa lifofane, mokoloko, noka ea nōka, tšireletso ea letsoapo, phekolo ea ntlafatso ea litsela le borokho le likarolo tse ling tsa boenjiniere, li ka fana ka matlafatso, ho thibela matlapa, mapetsong a mokhathala tseleng e katoang, mocheso le serame katoloso le mapetsong a ho honyela le mapetsong a latelang a bonahatsang, 'me E ka qhalakanya tsela e jereng khatello ea maikutlo le ho lelefatsa bophelo ba tšebeletso ea tsela.
• Matla a phahameng a tsitsipano le bolelele bo tlase: basalt fiber geogrid e thehiloe holim'a fiber ea basalt e le thepa e tala, 'me matla a ts'ebetso ea basalt fiber a phahame haholo, ho feta likhoele tse ling le tšepe e tloaelehileng. Ka nako e ts'oanang e na le modulus e phahameng, e na le khanyetso e phahameng ea deformation, fracture elongation e ka tlase ho 3%.
• Ha ho na nako e telele e ts'oanelang: e le ntho e matlafatsang, e nang le bokhoni ba ho hanela deformation tabeng ea mojaro oa nako e telele hore creep resistance e bohlokoa haholo, fiber ea basalt e ke ke ea qhoma, ho etsa bonnete ba hore sehlahisoa se ka boloka ts'ebetso ea nako e telele.
• Botsitso bo botle ba 'mele le lik'hemik'hale: fiber ea basalt ka boeona e na le khanyetso e matla ea acid le alkali corrosion, basalt geogrid e ka hanela mefuta e sa tšoaneng ea ho apara' meleng le khoholeho ea lik'hemik'hale, empa hape e khahlanong le khoholeho ea likokoana-hloko le phetoho ea boemo ba leholimo, ho netefatsa hore ts'ebetso ea eona ha e lahlehe.
• Botsitso bo botle ba mocheso: ntlha ea ho qhibiliha ha fiber ea basalt ka 1500 ° C kapa ho feta, tšebeliso ea nako e telele ea mocheso pakeng tsa -260 ° ~ 650 °, ho netefatsa hore basalt geogrid ts'ebetsong ea paving ho mamella botsitso bo phahameng ba mocheso.
• Kakaretso ea senotlolo se kentsoeng le thibelo: hobane basalt geogrid ke sebopeho sa letlooeng, konkreite ea asphalt ka kakaretso e ka kenngoa, e le hore ho thehoe senotlolo se kentsoeng ka mechine. Thibelo ena e sitisa motsamao oa li-aggregates, e le hore motsoako oa asphalt tabeng ea mojaro o ka finyella boemo bo ntlafetseng ba ho kopana, matla a phahameng a ho jara, ts'ebetso e ntle ea ho fetisa mojaro le ho fokotseha ho fokolang.
• 'Me ho lumellana ha motsoako oa asphalt: basalt geogrid ka mor'a ho phekoloa lisebelisoa tse koahetsoeng li etselitsoe motsoako oa asphalt, fiber e' ngoe le e 'ngoe e koahetsoe ka ho feletseng le asphalt e na le tekanyo e phahameng ea ho lumellana, kahoo ho etsa bonnete ba hore geogrid ea basalt e ka har'a asphalt e ke ke ea aroloa ho tloha motsoako oa asphalt, empa e kopantsoe ka thata hammoho.
• Khatello e khahlanong le mokhathala: basalt geogrid e ka holim'a asphalt holim'a lera, e ka ba khatello ea mabili holim'a tsela le ho qhalakanngoa ha khatello ea kelello le khatello ea maikutlo, ho thehoa ha sebaka sa buffer pakeng tsa libaka tse peli tsa khatello ea kelello, phetoho ea butle-butle ea khatello ea kelello ho e-na le phetoho ea tšohanyetso, ho fokotsa phetoho ea tšohanyetso ea khatello ea maikutlo holim'a asphalt. Ka nako e ts'oanang, bolelele bo tlase ba basalt geogrid bo fokotsa ho kobeha ha tsela, ho etsa bonnete ba hore tsela e katiloeng e ke ke ea etsahala deformation e feteletseng.
• Rutting e hanyetsanang le mocheso o phahameng: tšebeliso ea basalt geogrid sebakeng sa asphalt, e bapalang karolo ea skeleton karolong ea asphalt. Aggregate ka asphalt konkreite ka keriti, ho etsa composite mechanical notlela tsamaiso, fokotsa motsamao oa aggregates, ho eketsa transverse tlamang matla a asphalt holim lera, asphalt holim lera ea karolo e 'ngoe le tse ling tse, ho thibela sekontiri holim'a lera la push ho phetha karolo ea ho hanyetsa ho rutting.
• Anti low mocheso shrinkage cracking: maemong a tlaase mocheso, asphalt konkreite batang shrinkage, ho fella ka khatello ea kelello e tsitsipano, ha khatello ea kelello e feta matla a tensele ea asphalt konkreite, ho fella ka mapetsong. Basalt geogrid ts'ebelisong ea lera la asphalt holim'a asphalt, e ntlafatsa bokaholimo ba matla a ho tsieleha, e le hore matla a konkreite ea asphalt a ntlafatsoe haholo, a ka hanela khatello ea maikutlo e kholo ntle le tšenyo. Ho phaella moo, esita le haeba ka lebaka la sebaka sa libaka tsa mapetsong, mapetsong a hlahang khatello ea kelello, ka basalt geogrid e fetisetsa le ho nyamela, mapetsong a ke ke a fetoha mapetsong.
• Ho lieha ho fokotseha ha mapetsong a bonahatsang: ka asphalt e nang le basalt geogrid flat layer, thibela ho kuta kapa khatello ea kelello e bakoang ke meroalo ea sephethephethe, ho lokolla khatello, joalo ka lisebelisoa tsa matlafatso tsa asphalt konkreite, ho finyella sepheo sa ho lieha ho fokotseha ha mapetsong.

3.Tšebeliso ea geogrid e nang le fiber ea motheo
Geogrid ts'ebelisong ea lintlha tse kholo tsa matla, ho hanyetsa meokho, le ho kopanya mobu, ho tšoarella le moruo oa eona. Hajoale, geogrid e se e sebelisitsoe lebaleng la litsela tse kholo, bethe ea literene, mokoloko oa mobu, ntlafatso ea letsoapo la banka, ts'ehetso le sebopeho sa ho boloka, tokiso ea lera la mafika, tokiso ea ho ntlafatsa tsela le ho thibela le ho laola ho phatloha. Haholo-holo ts'ebeliso ea geogrid ntlafatsong ea litselana le thibelo ea mapetsong a bonahatsang. Reflection crack ke tsela ea joang bo joang bo boemong ka lebaka la ho fetoha ha mocheso kapa mojaro o moholo haholo 'me o hlahisa mapetsong,' me ka interlayer stress propagation ho ea holim'a tsela, hlahisa motsamao o otlolohileng kapa o otlolohileng pakeng tsa mekhahlelo le ho etsa hore tsela e phunyeletse. Tšebeliso ea geogrid e sebetsang hantle e ka ntlafatsa ka katleho matla a ho kuta ka har'a li-interlayer le ts'ebetso ea ho khathala tseleng, ho qhalakanya khatello ea maikutlo, kahoo ho thibela ka katleho ho etsahala ha mapetsong a litsela, le ho fokotsa haholo litšenyehelo tsa tlhokomelo ea litsela. Reflection cracking ke ketsahalo e atisang ho fumanoa mathōkong a asphalt. Bakeng sa mapetsong a bonahatsang holim'a tsela, ho beha lera la geotextile pakeng tsa sekontiri sa holim'a asphalt le underlayment e ka felisa kapa ea liehisa moloko oa mapetsong a ho bonahatsa ka holim'a lera, kahoo e lelefatsa bophelo ba tšebeletso ea tsela. Empa sekontiri sa asphalt se tšela mocheso ho fihlela ho 160 ℃, se fella ka geotextile kapa polymer geogrid fold, deformation, softening, e le hore ts'ebetso ea eona e fokotsehe haholo. E sebelisoa sebakeng sa asphalt pavement geogrid e molemo ka ho fetisisa ho sebelisa basalt fiber geogrid, hobane basalt fiber geogrid e na le mocheso o motle oa ho hanyetsa, le matla a phahameng, modulus e phahameng, elongation e tlaase, coefficient e tlaase ea ho atolosa mocheso le litšobotsi tse ling.
