Ubwoko bubiri bwa asfalt ivanga ibihingwa imikorere cyangwa ibikorwa muri rusange. Ihame ryibanze ryubwoko ubwo aribwo bwose bwibihingwa ni kimwe ni ukuvuga kubyara ivangwa rya asfalt. Ibinyoma bitandukanye muburyo ibicuruzwa byanyuma byateguwe. Bimwe mubikorwa bisanzwe byubwoko bwibihingwa byombi ni:
- Ingano zitandukanye ziteranya guhunika no kugaburira muri bin.
- Kugaragaza igiteranyo. Muburyo bwubwoko butandukanye igiteranyo cyerekanwe kugirango gikureho ubunini. Mugihe mubice byubwoko igiteranyo cyerekanwe kubitandukanya mubice bitandukanye.
- Kuma no gushyushya igiteranyo.
- Gushonga ububiko no kohereza bitumen
- Kubika no kohereza ibikoresho byuzuza.
- Bitumen, igiteranyo hamwe nibintu byuzuzwa bipimwa mubihingwa byubwoko. Aho muburyo bwubwoko bwibimera byongeweho kandi bigenzurwa na disiki ihindagurika.
- Gusohora ibishyushye bivanze asfalt mu gikamyo cyangwa silo yo kubika.
- Igenzura risanzwe kubwoko bwombi. Igenzura ibikorwa byuruganda ikaduha raporo yibipimo byingenzi.
Ibintu bine by'ibanze byo kuvanga ibihingwa bya Asfalt:
Hano haribintu bimwe byingenzi bihuriweho na asfalt byose bivanga. Bameze nkibi bikurikira:
- Kuma no gushyushya igiteranyo.
- Gupima igiteranyo, bitumen nibikoresho byuzuza.
- Kuvanga igiteranyo hamwe na bitumen nibikoresho byuzuza.
- Kurekura ibishyushye bivanze asfalt.
Mu bwoko ubwo aribwo bwose bwa asfalt ukuri kwipima ni ikintu cyingenzi. Hagomba kubaho ibipimo bihamye kandi byuzuye bipima, bitumen kimwe namabuye y'agaciro. Iyo gupima bihamye, tubona ibicuruzwa byanyuma byifuzwa nkuko biteganijwe nibisanzwe. Ifasha mukubaka imihanda myiza nkuko bisanzwe byashyizweho. Igihingwa cya asfalt gifite ubushobozi bwo kubika resept zitandukanye. Turashobora guhindura gukoresha resept zitandukanye kubikorwa bitandukanye nkuko bikenewe. Ndetse ni ngombwa kumenya ko kubika no gukoresha resept nyinshi ari ngombwa mugihe ukorana nabakiriya benshi. Iyo ufite ibisubizo byabakiriya batandukanye babitswe nawe biroroshye guhitamo uburyo bwihariye busabwa. Iyo resept yifuzwa imaze gutorwa ukanze bike birashoboka gukora AMP itanga ubuziranenge bukenewe bwa hoteri ivanze asfalt.
Intsinzi yikimera icyo aricyo cyose kivanze gisaba kuringaniza bihagije no guhuza ibice byose. Kuva i igihingwa cya asfalt ni ihuriro ryibikoresho bya mashini n amashanyarazi. Ni ngombwa ko ibice byose bikora murwego rwo gutanga ibisubizo byifuzwa. Birashoboka kubona ubudahwema nuburinganire mukwitonda no kuyobora. Ni ngombwa kugenzura ibimera byose mbere yo gutangira. Ni ngombwa gukora buri munsi, buri cyumweru, buri kwezi kubungabunga nkuko byasobanuwe nuwabikoze buri gihe. Ibikoresho byose nka agregate, lisansi, bitumen bigomba kugenzurwa ubuziranenge mbere yo gukoreshwa. Iyo ubushishozi bwubahirijwe biroroshye gukora ibikoresho bivanze neza biva mu ruganda rushyushye rwa sosiyete nziza.
Atlas nu Buhinde ikora kandi ikohereza ibicuruzwa bivangwa na asfalt.
Nibihe bigize ibice bishyushye bivanze asfalt?
Ashyushye ivanze asfalt igizwe namabuye yubunini butandukanye, amabuye, bitumen nibikoresho bihuza. Ashyushye ivanze asfalt itegurwa no gushyushya bitumen, igiteranyo no kuyivanga ku bushyuhe bwo hejuru.
Ni ubuhe bwoko 2 bwa asfalt?
Ubwoko 2 bwingenzi bwa asfalt nuburyo buvanze nubwoko bukonje. Kuvanga ashyushye asfalt byateguwe bishyushye kandi bigashyirwa mbere yuko bikonja. Imvange ikonje asfalt ntabwo ishyushye - ikorwa no kuvanga emulion, amazi na sima. Igiteranyo gikoreshwa mubukonje buvanze asfalt ntibishyushye.
Ni irihe tandukaniro riri hagati ya asfalt na bitumen?
Bitumen ni ibintu bibisi byamazi bikoreshwa mukubyara asfalt ivanze. Asfalt ni uruvange rwa agregate, umucanga na bitumen ku bushyuhe bwinshi. Bitumen ikora nk'ibikoresho bihuza umusaruro wa sima ya asfalt.
