i-bitumen yase-atural: I-petroleum icudiswa luqweqwe lomhlaba ixesha elide kwindalo kwaye idibana nomoya kunye nokufuma. I-oyile yayo ekhanyayo iyancipha ngokuthe ngcembe, kwaye i-bitumen ye-petroleum eyenziwe yi-concentration kunye ne-oxidation idla ngokuxutywa kunye nomlinganiselo othile weeminerali. Ibhitumene yendalo inokohlulwa ibe yibhitumene yechibi, ibhitumene yamatye, ibhitumene yangaphantsi kwamanzi, i-oyile ye-oyile, njl.
Ibhitumene yelitye yinto efana nebhitumene ephuma kwipetroleum yakudala ingena kwiintanda zamatye, kwaye emva kwamakhulu ezigidi zeminyaka yokubekwa, utshintsho, iadsorption, kunye nokudityaniswa, phantsi kweziphumo ezidityanisiweyo zamandla obushushu, uxinzelelo, i-oxidation, i-catalysts, iibhaktheriya, njl.

Ibhitumene eguquliweyo yamatye isebenzisa ibhitumene yamatye njengesilungisi kwaye idityaniswa nebhitumene yematrix ngokomlinganiselo othile wokudibanisa. Ibhitumene elungisiweyo iveliswa ngeenkqubo ezinjengokuxuba, ukucheba nophuhliso. Ibizwa ngokuba yi-NMB.
Umxube webhitumene eguquliweyo yamatye ngumxube oveliswa yinkqubo "emanzi" esekelwe "kwibhitumene eguquliweyo yamatye" okanye umxube oveliswe yinkqubo "eyomileyo" esekelwe "kwi-rock bitumen modification".
"Indlela eyomileyo" inkqubo "Indlela yokomisa" ithetha ukuba emva kokugalela izinto ezimbiwa ezimbizeni kwimbiza yokuxuba, isilungisi sebhitumene yamatye sidityaniswa kwimbiza yokuxuba kwaye ixutywe nezinto ezimbiwa ezimbiwa ezomileyo kangangexesha elithile, emva koko zitshizwe ngaphakathi. ibhitumene yematrix yenkqubo yokuxuba ibhitumene emanzi.
Inkqubo “yendlela emanzi” inkqubo “indlela yokumanzisa” ithetha ukuba isilungisi sebhitumene yamatye kunye nesiseko sebhitumene kubushushu obuthile ziqale zixutywe, zichetywe, ze zenziwe zibe yibhitumene egqityiweyo yamatye, emva koko itshizwe embizeni yokuxuba ukuze ixutywe nayo. intsimbi ekrwada. Inkqubo yokuxuba umxube webhitumene.
