Kugirango duhuze ibisabwa bifatika, Asfalt Mixtl, nibikoresho nyamukuru kubikorwa byo kuvanga Asfalt, nabyo buri gihe biravugururwa. Ihuriro ryuzuye ryikora ashalt ni ibicuruzwa bigezweho. Nubwo ikoresha ari imwe, ihuriro ryikora ashalt ashalt biragaragara ko riruta ibikoresho gakondo. Noneho hari ibisabwa bidasanzwe kugirango bikoreshwe?

Igihingwa cyo kuvanga Asfalt cyiyemeje cyane cyane ukurikije imiterere nyayo yumwanya wubwubatsi, kugirango rishobore guhuza ibikenewe kandi bishyiraho imikorere ya sitasiyo ivanze. Birumvikana ko guhitamo igihingwa cya asfalt kitazaba byoroshye. Hariho ibintu byinshi bigomba gusuzumwa, kandi ingingo z'ingenzi ni zikurikira.

Mu bihe byimvura byimvura mugihe cyimvura, uburyo bwo gukoresha bitumen (ibihimbano: asfaltene na resin) ibwubatsi busuye hamwe nubuzima bwimiterere, ntibizahindura ubuziranenge no gutera imbere kubaka amazi yose. Ibikoresho bitesha umutwe bya bitumen ni imvange yijimye-yumukara igizwe namasuka yuburemere butandukanye bwa molekari hamwe nibikomoka ku badamuka. Nubwoko bwuzuye-busa. Ni amazi, afite ubuso bwirabura, kandi arashonje muri karubone. Bitumen ni ibintu bisanzwe bya kama bidafite amazi, ubushuhe-ibimenyetso kandi birwanya ruswa.  Bitumen irashobora kugabanywa ahanini muburyo butatu: Amakara ya Tutumen na biturumen, muri bo, amakara tar, ikibuga cyamakara nigicuruzwa cya couking. Petroleum bitumen ni ibisigara nyuma yamavuta yumwimerere, ni ubuhe buryo bwibihe byigihe cyo gukoresha ibikoresho bya bitumen (ibisobanuro: ibintu byiza bishobora kurenza uwo muhanganye)?

Umukiriya wa Nigeriya ni isosiyete ishinzwe ubucuruzi bwaho, cyane cyane ikora ibikorwa bya peteroli na bitumen na hejuru nibicuruzwa bitarenze. Umukiriya yohereje icyifuzo cyo kubaza kuri sosiyete yacu muri Kanama 2023. Nyuma y'amezi arenga atatu yo gutumanaho, amaherezo yamenyeyemeje. Umukiriya azategeka ibice 10 bya bitumen decanter.

Ni ubuhe buryo rusange bwo gukora bwa bitumen (ibihimbano: asphaltene na resin) ibikoresho byo guta agaciro bya bitumen. Imikorere), ikoreshwa mu gushyigikira ibikoresho byubushyuhe bukabije bwibikoresho byo gushyushya amavuta. Ibikoresho bya Decants bitumen bifite imirimo yo gutanga kwa Barrel, gukuraho, kubika, kuzamura ubushyuhe, ibirangisho bya Slag, nibindi nibicuruzwa byingenzi kubigo byubwubatsi byo murwego rwo hejuru. Ibikoresho bya bitumen birashobora gukoreshwa mugukuraho barrel.

Ukurikije ibiranga umuvuduko mwinshi uvanze ibikoresho bya bitumen bishonga, bishyushya ibikoresho byo gushonga bya bitling, bikaba bishobora guhuza ibikoresho bya bitumen bishonga bishonga bishonga ibikoresho byo gushyushya. Ikigega cyo gushyushya. Ubushyuhe bwa Bishyushye Bitumen Barrele igera kubushyuhe bukwiye.
