Bitumen (ibihimbano: Asphaltene na resin) Ibikorwa byo gukora bimaze igihe kinini bibanda cyane mubushakashatsi no guteza imbere bitumen (ibihimbano: ibisigazwa: Asphaltene na resin). Ibishushanyo hamwe na resin), reka abakozi bacu ba tekinike baragusobanurire. Nizera ko bizagufasha kumva ibicuruzwa.

Bitumen (ibihimbano: Asphaltene na resin) muri bitumen (ibihimbano: Imiterere yubuyobozi bwa Byumen yatumen ikubiyemo amafaranga mabi, mugihe iminyururu ya bitumen ikubiyemo amafaranga mabi, mugihe amatsinda ya Hydrophile yinjiye mu cyiciro cy'amazi. Noneho ibice byamazu n'amazi bihujwe, bigabanya amakimbirane yubuso hagati yabo (ibisobanuro: Imbaraga zo gutwara ibinyabiziga mugihe ibintu bikorerwa imbaraga za tensile). Byongeye kandi, kubera ko ibice bya bitumen birimo amafaranga mabi kandi bivuguruzanya, kubabuza guterana, kwimuka kwatumen birashobora kugumana urwego runaka rwubusa no gutuza (imvugo: nta giciro). Ibiranga amafaranga mabi bigenwa no kurera amashuri mabi yitsinda rya hydrophobic rya bitumsifier cyangwa igice cya hydrocarbone. Niba ari bibi, ibice bya bitumen birimo amafaranga mabi, hamwe na emulsion yavuyemo ni emalic bitumen. Ibinyuranye, ni emunion ya tutic bitumen. Niba uduce turumwe dufite amafaranga mabi kandi meza, emulsion ni viromasi ya zatumen; Byongeye kandi, hariho kandi amazi atari aimen.
