Gusubiza Umuhanda wa Arizona kuri crement centume beto birashobora gusa kwerekana inyungu zo gukoresha diyama gusya nkubundi buryo bwo gusya no kuzura. Outlook yerekana ko mugihe cyimyaka 30, ibiciro byo kubungabunga bizagabanuka na miliyari 3.9 USD.
Iyi ngingo ishingiye kuri viranar yabanje kuba mugihe cyishyirahamwe ryimbere kandi risya (IGGA) mu nama ya tekiniki mu Kuboza 2020. Reba demo yuzuye hepfo.
Abatuye muri Phoenix bashaka imihanda yoroshye, nziza, kandi ituje. Ariko, kubera ubwiza bwabaturage buturika mukarere noguka amafaranga adahagije kugirango tujye, imiterere yo mumuhanda muri kariya gace yagabanutse mumyaka icumi ishize. Ishami rishinzwe ubwikorezi rya Arizona (Adot) ryiga ibisubizo byo guhanga kugirango nkomeze umuyoboro wacyo kandi utange ubwoko bwimihanda iteganya.
Phoenix ni umujyi wa gatanu cyane muri Amerika, kandi uracyakura. Umujyi wa Milemetero 435-yimihanda n'ibiraro bibungabungwa n'ishami rishinzwe ubwikorezi bwa Arizona (ADOT) hagati, inyinshi muri zo zigizwe n'imihanda ine ifite imihanda miremire y'ikinyabiziga (HOV). Hamwe n'ingengo y'imari y'ubwubatsi muri miliyoni 500 z'amadolari y'Amerika, mu karere ubusanzwe bitwara imishinga 20 kugeza 25 yo kubaka ku muhanda wo mu muhanda.
Arizona yakoresheje gahunda ya beto kuva muri 1920. Beto irashobora gukoreshwa mumyaka mirongo kandi ikeneye gusa kubungabunga buri myaka 20-25. Kuri Arizona, imyaka 40 yubunararibonye bwatsinze bwatumye ikoreshwa mugihe cyo kubaka umuhanda munini wa leta muri za 1960. Muri icyo gihe, gushushanya umuhanda hamwe na beto byasobanuraga gukora ibiciro ukurikije urusaku rwumuhanda. Muri iki gihe, ubuso bwa beto burarangiye amatwi (gukurura icyuma hejuru yubuso bwa beto perpendicular kumuhanda), kandi amapine atwara ikinamiro kitoroshye azatanga urusaku,. Mu 2003, kugirango dukemure ikibazo cyurusaku, 1-muri. Asfalt Rubber Gutesha agaciro (AR-ACFC) yakoreshejwe hejuru ya sima ya centland beto (PCC). Ibi bitanga isura ihamye, amajwi atuje kandi meza. Ariko, kubungabunga ubuso bwa ACFC byagaragaye ko ari ikibazo.
Ubuzima bwa AC-ACFC bugera kumyaka 10. Umuhanda wa Arizona warenze ubuzima bwabo kandi ushaje. Gutsirwa n'ibibazo bifitanye isano n'ibibazo by'ibiyobyabwenge na Minisiteri yo gutwara. Nubwo gucibwa gusa bivamo gusa gutakaza hafi ya santimetero 1 z'uburebure (kubera ko inch nini ya rubber atandukana hepfo), ingingo yatinze ifatwa nkimyitozo ngororamubiri kandi ifatwa nkimbaraga ikibazo.
Nyuma yo kwipimisha diyama, hejuru-igisekuru-gisebanya, no kurangiza ubuso bwa beto hamwe nisuka cyangwa micromilling, iyemeza ko imiterere ishimishije igaragara hamwe nimibare myiza (nkuko bigaragara kuri IRI ) hamwe nu myuka nke. Randy Everett na Arizona Minisiteri ishinzwe gutwara abantu
Arizona ikoresha indangagaciro mpuzamahanga (IRI) kugirango igirebire umuhanda, kandi umubare wagabanutse. . Nk'uko ibipimo bya IRI byakorewe mu 2010, 72% by'imihanda minini y'imbabazi muri ako karere biragoye. Kugeza 2018, iyi ngingo yari imaze kugwa kuri 53%. Inzira nyabagendwa zigihugu zerekana kandi inzira yo hepfo. Ibipimo muri 2010 byerekanaga ko 68% byimihanda yari imeze neza. Kugeza 2018, uyu mubare wagabanutse kuri 35%.
Nkuko ibiciro byiyongereye-kandi bije ntibyashoboraga gukomeza - muri Mata 2019, Adot yatangiye gushakisha uburyo bwiza bwo kubikamo no mubanjirije. Kuri pavement bikiri muburyo bwiza mugihe cyimyaka 10 kugeza kuri 15 urwego rwumucyo, gahoro gahoro gahoro emalsion), cyangwa gusana ibinogo. Kuri kaburimbo irenze ubuzima bwateguye, amahitamo imwe ni ugusya asfalt yangiritse hanyuma ashyireho impyisi nshya ya rubhalt. Ariko, kubera ubuso bwakarere bigomba gusanwa, ibi birerekana ko bihenze cyane. Indi mbogamizi ku gisubizo icyo ari cyo cyose gisaba gusya gusfale ni uko ibikoresho byo gusya bizagira ingaruka no kwangiza ibintu biri imbere, kandi gutakaza ibikoresho bifatika ku ngingo zikomeye.
Byagenda bite iyo Arizona yagarutse hejuru yumwimerere wa PCC? Adot azi ko umuhanda utunganya muri leta wagenewe gutanga ubuzima burebure. Ishami ryamenye ko niba niba bashobora gukoresha munsi ya PCC kugirango batezimbere hejuru yumwimerere kugirango bakore umuhanda utuje kandi ugenda, umuhanda usanwa urashobora kumara. Ni kandi munsi ya Asfalt.
Mu rwego rw'umushinga kuri SR 101 Amajyaruguru ya Phoenix, yakuweho, Ad-ad-ACFC yashizwemo ibice bine byikizamini bizakoresha ibintu bizeza bizakoresha ibintu bihari bizimya ibintu biriho mugihe arirora neza. Ishami ryasuzumye Diamond Gusya na Disito hamwe n'ibisekuru bisekeje (NGCs), imiterere ifite umwirondoro wagenzuwe kandi umanuka, umanuka, urusaku rw'urusaku rwinshi. Adt nawe atekereza gukoresha gusya (inzira aho imashini iyobora imipira yumuhanda kugirango atezimbere ibiranga amakimbirane) cyangwa micro-mino kugirango urangize ubuso bwa beto. Nyuma yo kwipimisha buri kintu, Adot yiyemeje ko imiterere ndende yasya ya diyama itanga isura ishimishije kimwe nubunararibonye bwiza bwa IRI) nijwi rito. Inzira yo gusya ya diyama nayo yagaragaye ko yitonda kugirango irinde uturere duto, cyane cyane hamwe ingingo, zangiritse mbere musya. Gusya diyama nayo nigiciro cyiza.
Muri Gicurasi 2019, Adot yahisemo diyama-gusya igice gito cya SR 202 giherereye mu majyepfo ya Phoenix. Umuhanda w'imyaka 15 wa ACFC wari urekuye kandi ushizemo ko amabuye arekuye ajugunywa ku kirahure, kandi abashoferi binubira ikirahuri byangijwe n'ibuye riguruka buri munsi. Umubare w'igihombo muri kano karere uruta ubundi uturere tw'igihugu. Umuhanda nawo ni urusaku kandi rugoye gutwara. Adot yahisemo diyama yarangiye kumihanda ibiri yiburyo kuri sr 202 igice cya kilometero ndende. Bakoresheje indobo itwara kugirango ukureho igice gihari cya ACFC nta cyangiza beto hepfo. Ishami ryagerageje neza ubu buryo muri Mata igihe bari kungurana ibitekerezo byo gusubira mumuhanda wa PCC. Umushinga umaze kurangira, uhagarariye ADOT yabonye ko umushoferi yagendaga ava mu nzira ya ACFC kuri diyama yaka mu nzira nyabagendwa kugira ngo ibone imigendekere myiza n'amajwi.
Nubwo imishinga yose yicyitegererezo yarangiye, ibanziriza izinjirije ibiciro yerekana ko kuzigama bifitanye isano no gukoresha amashusho ya beto na diyama, n'amajwi bishobora kugabanya kubungabunga na miliyari 3.9 z'amadolari. Mugihe cyimyaka 30. Randy Everett na Minina yo gutwara abantu
Muri iki gihe, ishyirahamwe rya leta ya Maricopa (Mag) ryasohoye raporo isuzuma urusaku rw'imihanda yaho ndetse n'ahantu. Raporo yemera ingorane zo kubungabunga umuhanda kandi wibanda ku miterere y'urusaku rw'umuhanda. Umwanzuro w'ingenzi ni uko kuberako urusaku rwa AN-ACFC rubura vuba, "Diamond Face Fackalt Asfalt." Ikindi giterano icyarimwe ni amasezerano yo gutanga amasoko yemerera diyama yasya mu rwiyemezamirimo yazanywe no kubungabunga no kubaka.
Adot yizera ko igihe kirageze cyo gutera intambwe ikurikira kandi ugatangira gutangira umushinga munini wa diyama kuri SR 202 muri Gashyantare 2020. Umushinga utwikiriye igice kilometero enye, igice kinini, harimo igice kinini, harimo igice kinini, harimo ibice binini. Agace kari kanini kuburyo kangana no gukuraho asfalt, imashini isya irakoreshwa. Ishami rigabanya imirongo muri rubber asfalt yo gusya gusya gukoresha nkuyobora mugihe cyo gusya. Mugurohereza umukoresha kugirango ubone ubuso bwa PCC munsi yigifuniko, ibikoresho byo gusya birashobora guhinduka no kwangirika kuri beto yibanze birashobora kugabanywa. Ubuso bwa diyama ya nyuma ya SR 202 buhuye nibipimo byose bya ADTH - biratuje, byoroshye kandi birashimishije - ugereranije nubuso bwa asfalt, agaciro ka IRI byari byiza cyane muri 1920 na 1930. Ibi biranga urusaku bishobora kuboneka kuko nubwo pavement nshya ya ACFC igera kuri 5 db igihuru cya db, mugihe cya kaburimbo ya ACFC ikoreshwa mumyaka 5 kugeza 9, ibisubizo byayo biragereranijwe cyangwa hejuru ya DB. Ntabwo ari urwego rwurusaku rwa SR rushya rwa SR 202 rubanda cyane kubashoferi, ariko umuhanda wana utanga urusaku ruto mumuryango uri hafi.
Intsinzi yimishinga yabo yo hambere yatumye Adot atangira izindi diyama eshatu zo gusya pilote. Gusya diyama ya loop 101 ikirambo cyubusa. Diyama yasya kuzenguruka 101 Pima Kubohanda mu ntangiriro ya 2021, no kubaka loop 101 I-17 kugeza ku ya 75 kugeza ku mashyaka ya 75 ateganijwe gukorwa mu myaka itanu iri imbere. ADOT izakurikirana imikorere yibintu byose kugirango urebe inkunga ingingo, niba beto yakuyeho, no kubungabunga amajwi no kugenda neza.
Nubwo imishinga yose yicyitegererezo yarangiye, amakuru yakusanyijwe kuburyo asobanura gusuzuma Diamonds gusya nkubundi buryo bwo gusya no kuzura. Ibisubizo byabanjirije iperereza ryabigenewe byerekana ko kuzigama bifitanye isano no gukoresha kaburimbo ya beto na diyama byoroshye kugirango bigabanye ibiciro byubukungu kugeza kuri miliyari 3,9.
Mugukoresha kaburimbo ihari muri Phoenix, ntabwo ingengo yimikorere gusa ishobora kugabanywa kandi imihanda myinshi ikomeza guhangayikishwa neza, ariko kuramba bya beto ireba iyo guhungabana bijyanye no kubungabunga umuhanda bigabanuka. Icy'ingenzi cyane, abaturage bazashobora kwishimira hejuru yo gutwara neza kandi ituje.
Randy Everett nuwo umuyobozi ushinzwe ishami mu ishami rishinzwe gutwara abantu bari hagati arizona.
IGGA ni ishyirahamwe ry'ubucuruzi ridaharanira inyungu ryashyizweho mu 1972 n'itsinda ry'abahanga mu nganda, ryahariwe iterambere rya diyama no gushushanya kuri Portland sima na Asfalt Flab. Mu 1995, IGGA yinjiye mu ishyirahamwe rya pavement ya Pavement y'Abanyamerika (ACPA), ikora ubufatanye bwa IGGA / ACPA / ACGA / ACPA CP3). Muri iki gihe, ubu bufatanye ni umutungo wa tekiniki n'umuyobozi utegura inganda mu kwamamaza ku isi hose, hagaragaye igice cya pavement cyateguwe. Inshingano ya IGGA ni uguhinduka umutungo wambere nikoranabuhanga mu kuzamura no kuzamura no gukoresha neza diyama no gutondeka, ndetse no kugose kwa PCC.
