Bitumen (ibihimbano: asfaltene na resin) abakora inganda zikora tank kuva kera bibanze kubushakashatsi no guteza imbere ibigega byiza bya bitumen (ibihimbano: asfaltene na resin) kugirango bigufashe kumva neza ibigega byacu bya bitumen (ibihimbano: asfaltene na resin). Ibigega bya Asphaltene na resin), reka abakozi bacu tekinike bagusobanurire. Nizera ko bizagufasha kumva ibicuruzwa.
Bitumen (ibihimbano: asfaltene na resin) ikigega Muri bitumen (ibihimbano: asfaltene na resin) -imicungire y’amazi, imiterere ya molekuline ya emulifier ya bitumen igenda hagati ya bitumen nurupapuro rwamazi, kandi itsinda ryanga amazi yimiterere ya molekile ni adsorbed hejuru yubuso bwa bitumen burimo ibicuruzwa bibi, mugihe amatsinda ya hydrophilique yinjira mugice cyamazi. Noneho ibice bya bitumen n'amazi birahujwe, bigabanya ubukana bwubuso hagati yabyo (ibisobanuro: imbaraga zo gutwara iyo ibintu bikorewe imbaraga zingana). Byongeye kandi, kubera ko ibice bya bitumen bikubiyemo kwishyuza nabi no guterana amagambo, bikababuza guterana hamwe, emulioni ya bitumen irashobora gukomeza urwego runaka rwuburinganire n'ubwuzuzanye (imvugo: ihamye kandi ihamye; nta gihinduka). Ibiranga kwishyurwa nabi bigenwa nuburyo bubi bwamatsinda ya hydrophobique ya emulifier ya bitumen cyangwa igice cyumunyururu wa hydrocarubone. Niba ari bibi, ibice bya bitumen birimo ibintu bibi, kandi emulsiyo yavuyemo ni cationic bitumen emulsion. Ibinyuranye na byo, ni cationic bitumen emulsion. Niba ibice bya bitumen bifite ibiciro bibi kandi byiza, emulion ni zwitterionic bitumen emulsion; hiyongereyeho, hari n'amazi ya bitumen atari ionic.
