Dhau li ntawm qhov tshwm sim nyob rau hauv natural deposits, asph alt ntaub ntawv raws li ib tug byproduct ntawm refining txheej txheem. Daim ntawv tshwm sim ntawm asph alt feem ntau hu ua "Crude bitumen.” Tsis tas li ntawd, cov khoom no muaj viscosity zoo ib yam li cov viscosity ntawm txias molasses. Cov ntaub ntawv hluavtaws ntawm asph alt tuaj yeem hu ua "refined bitumen." Cov tshuaj no yog tsim los ntawm cov fractional distillation ntawm cov roj crude ntawm qhov kub thiab txias.
Kev thov loj ntawm asph alt yog hauv kev tsim kho. Hauv daim ntawv thov no, cov tshuaj no yog cov kua nplaum los yog cov ntawv khi, uas tuaj yeem sib xyaw nrog cov sib xyaw ua ke hauv kev tsim cov pob zeb asph alt. Tsis tas li ntawd, cov khoom no yog ib qho tseem ceeb hauv kev tsim cov khoom siv dej tsis zoo, xws li kev sib khi lub ru tsev tiaj tus.
