10. Ni iki ejo hazaza hateganijwe guhindura asfalt no gushaka inzira nziza?

Umurima waGuhindura Asfaltikomeza guhinduka, iyobowe nibikenewe biramba cyane, bikora ibiciro, kandiirambyepavements. Ibihe byinshi bishimishije ni uguhindura ejo hazaza:

• Iterambere rya Chilymer Chimie:Ubushakashatsi burakomeza muburyo bushya bwapolymersnaguhinduratekinike. Ibi bikubiyemo iterambere rya polymes reactive nkaElvaloy ™ kubisubiramo, kora sisitemu ya Hybrid ihuza ibitandukanyeimpinduka, kandi gushushanya polymene hamwe no kurwanya neza gusaza (ultravioleturumuri na okiside) nakwangirika.
• Kongera gukoresha ibikoresho byatunganijwe:Kuramba ni umushoferi ukomeye. Ubushakashatsi bukomeye bwibanze ku buryo bwo hejuru ku ijanisha ryinshi ryaplastics, reberi(Kuva ku mapine), kandi yagaruwe na kaburimbo ya Asfalt (rap) muriyahinduwe asfaltutabangamiye.ImpindukaGira uruhare runini mu guhuza ibi bikoresho.
• Bio-binders:Hariho inyungu zigenda zikura mugutezimbere asfalt ikomoka muburyo cyangwa gusa kubikoresho byongerwa (bio-amavuta, ibiti biva mubiti, nibindi) nkibindi bikoresho bya peterolisima. GuhinduraTekinike irashobora guhuzwa nubu bwoko bushya bwa binders.
• Nanotechnology:Abashakashatsi barimo gushakisha imikoreshereze ya Nanomarial (nka nanoclay cyangwa karubone nanotubes) uko ubushoboziasfaltKugirango ugere kumikorere ikomeye no mubiciro byo kwiyongera cyane.
• Ivanga-Ivanga Asfalt (WMA) Tekinoroji:Mugihe atari byizaguhindura, Technologies WMA yemerera asfaltimvange(harimoyahinduwe asfalt) Gukorerwa no gushyirwa ku bushyuhe bwo hasi. Ibi bigabanya ibyo kurya byingufu, imyuka, numbunzi kumugaragaro abakozi, guhuzairambyeintego. Akenshi, WModitives zikoreshwa muguhuza hamwePolymer yahinduye binders.
• Ibisobanuro bishingiye ku mikorere:Hariho impinduka zigana kumurongo usobanuraIbisabwa(urugero, kurwanya guterana,guswera) aho gutanga ibitekerezo byihariye. Ibi bishishikariza guhanga udushya kandi bituma abatanga gukoresha nezaguhinduraingamba (nko gukoreshaElvaloy ™ kubisubiramo) Guhura nibyo bikoresho.

Nkumusezi wiyemeje ubuziranenge no guhanga udushya, dukurikirana neza izi nzira. Intego ikomeza kuba imwe: gutanga ibikoresho nkacuYahinduwe asfaltIbyo bituma kubaka imihanda bimara igihe kirekire, kora neza munsi yimihangayiko, bisaba kubungabunga bike, kandi utanga umusanzu kurenza byinshiirambyeUmuyoboro wa Remezo ku isi. Urugendo rwaGuhindura Asfaltni kure cyane, usezeranya nibintu byiza kuriinziracy'ejo.

Ibyingenzi bifata kwibuka:

• Yahinduwe asfalt (pma):Asfalt isanzwe ya Asfalt yazamuyepolymerscyangwa izindiimpindukakunoza imikorere.
• Inyungu zikomeye:Kongera kurwanya Kuvura, Umunaniroguswera, ubushyuhe, naubuhehereibyangiritse, biganisha ku gihe kirekireUmurimo wa Pavementn'ubuzima bwo hasi-cycleibiciro.
• Ahinduranya abantu: Sbs(Elaspemer),Eva(plaleslamer), no gutera imbere polymesElvaloy ™ kubisubiramo. Reberinaplasticsnabyo bikoreshwa.
• Kuzamura imikorere: Polymerskora umuyoboro ushimangira muri asfalt, utezimbere gukomera kuriubushyuhe bwo hejuruno guhinduka kuriUbushyuhe buke.
• Kuramba: Pmabigira uruhare mu kuramba kugeza igihe kirekireUmuhanda Ubuzima, kugabanya kubungabunga, nubushobozi bwo kwishyirirahorecycledibikoresho.
• Ubwiza ni ngombwa:KwipimishaPgGutanga amanota, DSR, BBR), kugenzura inzira, kandi birakwiyeIkwirakwizwani ngombwa kugirango ubone imikorere ihamye.
• Ibintu byo Guhitamo:GuhitamoPmabiterwa n'ikirere,Umuhanda, imikorere yihariye ikeneye, igiciro, nibintu byaho. Ubufatanye n'abatanga ubumenyi ni urufunguzo.
• Ibihe by'ejo hazaza:Wibande kuri polymers zateye imbere, yongerewe gusubiramo, bio-binders, yanotechnology, nibisobanuro bishingiye kumikorere.

Nugusobanukirwa no gukoreshaPolymer yahinduye asfalt, abafatanyabikorwa nka Mark Thompson n'inganda bakorera barashobora kubaka neza, barushijeho kwihangana, nibindi byinshiirambyeIbikorwa remezo by'ejo hazaza.
