Mugihe cyimvura ikomeje mugihe cyimvura, nigute wakoresha bitumen idakize (ibigize: asfaltene na resin) itwikiriye amazi hamwe nubwubatsi bwa membrane, mugihe cyose nta mazi meza afite hejuru yubutaka mugihe cyo kubaka, ntabwo bizagira ingaruka kuri ubuziranenge niterambere ryubwubatsi butarimo amazi. Ibikoresho bya Bitumen ni ibikoresho byijimye-umukara bivanze bigizwe na hydrocarbone yuburemere butandukanye bwa molekile hamwe nibikomoka kuri metallic. Nubwoko bwamazi menshi-yijimye. Ifite amazi, ifite ubuso bwirabura, kandi irashonga muri karubone disulfide. Bitumen nigikoresho kama cimentitike kama kitarimo amazi, kitagira amazi kandi kirwanya ruswa. Bitumen irashobora kugabanywa mubwoko butatu: ikara ryamakara, peteroli ya bitum na bitumen bisanzwe: muribo, ikara ryamakara nigicuruzwa cya kokiya. Ibikomoka kuri peteroli nibisigara nyuma yo gutobora amavuta yumwimerere, none ni izihe nyungu zigihe cyo gukoresha ibikoresho bya bitumen byahinduwe (ibisobanuro: ibintu byiza bishobora gutsinda uwo duhanganye)?

Ubwoko bwa Solvent (imitungo: ibonerana, idafite ibara) ubwoko bwa coating hamwe namazi ashingiye kumazi bisaba igihe cyo gukora firime, igihe cyo kumisha hejuru nigihe cyo gukama nyuma yo kurangiza kubaka. Mubihe by'imvura, ibi bihe byo gutegereza biziyongera cyane, bityo bigire ingaruka kumajyambere yumushinga wose. Rubber bitumen idakize (ibigize: asfaltene na resin) igipfunyika kitagira amazi kirashobora gushyirwaho ibikoresho bizunguruka kugirango hubakwe ibice bikingira nyuma yo kubaka, kandi ntibizagerwaho n'ingaruka z’ikirere na gato.
Igice fatizo kigomba kuba cyoroshye, gikomeye, gisukuye, kandi kitarimo amazi yagaragaye. Uruhu urwo arirwo rwose, imisumari ikora, amabuye ya minisiteri, nibindi bigomba gusukurwa. Ibikoresho byahinduwe na bitumen ni ukongeramo ibivanze hanze (modifiers) nka reberi, resin, polymers ndende cyane, ifu ya reberi nziza cyane cyangwa ibindi byuzuza, cyangwa gufata ingamba nko gutunganya okiside yoroheje ya bitumen kugirango uvange asfalt cyangwa asfalt. Imbere n'inyuma, imizi y'umuyoboro, umusingi wibikoresho nibindi bisobanuro bya bitumen binder yakozwe mugutezimbere imikorere yibikoresho bigomba gukorwa muri arc, kandi diameter ya arc igomba kuba irenga 50mm. Koresha intoki zogusana kugirango usane ingingo, bolts (igizwe numutwe ninsinga), kwangirika kwaho (gusobanura: bivuga kubora, kuzimira, isuri, nibindi) nibindi bidakomeye (ibisobanuro: ibice bito ariko bidakomeye) kimwe nibice hamwe nimpande . Koresha ibice byinyongera mubice bidakomeye nkinguni. Ubuso bwibanze bwibibanza byubutaka bigomba kuba byoroshye kandi bikomeye. Ntabwo hagomba kubaho inenge nko kumusenyi no gutobora; Imbere n'inyuma bigomba gukorwa muburyo bwa arc (ibisobanuro: ni umurongo mwiza) cyangwa inguni ya obtuse. Muri icyo gihe, ubuso bugomba kuba busukuye kandi bwumutse, kandi kubaka ibice bitarimo amazi birashobora gukorwa nyuma yo kunyura mu bwihisho.
Mugihe cyubwubatsi, usibye ingamba zubwubatsi zisanzwe, ugomba no kwitondera cyane iteganyagihe kandi ugategura neza gahunda yo kubaka. Mugihe cyimvura ihagarara, ibikoresho bya asfalt byahinduwe bivangwa na reberi, resin, polymers nyinshi ya molekile, ifu ya reberi nziza cyane cyangwa izindi Fillers hamwe nibindi bivanga hanze (modifiers), cyangwa ingamba nka okiside yoroheje ya bitumen, irashobora gukoreshwa mugutezimbere imikorere ya asfalt cyangwa ivangwa rya asfalt. Mugihe cyimvura yubaka ibyuma bya bitumen, hagomba gukorwa imirimo yo kurwanya anti-skid kugirango hirindwe ibikoresho byubwubatsi nimpanuka zabakozi.
Imihanda nibikoresho byubatswe bigomba kuba bifite amazi meza, kandi ukagerageza kureba niba imvura ihagarara kandi amazi akuma kugirango birinde amazi menshi kubutaka. Menya neza ko ibikoresho byubwubatsi nibikoresho birinzwe imvura nubushuhe. Ugereranije nubwubatsi mugihe cyimvura, kubaka ibihe byubukonje mugihe cyimbeho bifite byinshi bisabwa kubikoresho n'abakozi. Ubushyuhe buke, imvura, shelegi, na barafu byose bigerageza kubaka amazi. Muri rusange, iyo winjiye mubidukikije munsi ya 0 ℃ mugihe cyitumba, ibibanza byinshi byubaka bihitamo guhagarika kubaka no gutegereza ko ikirere gishyuha mbere yo gutangira akazi.
Igihe cy'ubushyuhe buke mu gihe cy'itumba ni kirekire cyane. Gahunda yo kubaka imaze gukomera, tugomba guhangana nikibazo cyo kubaka ubushyuhe buke mu gihe cy'itumba. Kumashanyarazi (imitungo: ibonerana, idafite ibara) andika amazi adasukuye hamwe namazi ashingiye kumazi, niba kwiyongera kwigihe cyo gukora firime, igihe cyo kumisha hejuru hamwe nigihe cyo gukama mugihe cyimvura ntibituma kubaka bidashoboka, hanyuma mubihe byubushyuhe buke muri igihe cy'imbeho Icyerekezo cyerekana cyane ko bidashoboka kubaka. Nyamara, asfalt idakize (ibigize: asfaltene na resin) ibishishwa bitarimo amazi hamwe nibintu bimwe bigizwe nibice birenga 99% ntabwo bafite iki kibazo. Umubyimba ukenewe kugirango wirinde amazi urashobora kugerwaho nyuma yo gutera cyangwa gusiba, kandi ibikoresho bizunguruka birashobora guhita bishyirwaho. Cyangwa ibikoresho bya firime birashobora gukoreshwa. Ibintu ugomba kwitondera mugihe ukoresheje ibikoresho byahinduwe bya asfalt mubihe bitandukanye.
