Bitumen (muaj pes tsawg leeg: asphaltene thiab cobhen) cov khoom siv meterter xav kom yauv kis tau qee yam. Dab tsi yog cov txheej txheem ntsuas tseem ceeb rau nws? Kuv tsis paub ntau npaum li cas peb tau paub tiag tiag. Peb yuav tsum nkag siab cov ntaub ntawv yooj yim ua ntej siv nws. Tam sim no cia kuv piav qhia nws hauv kev nthuav dav rau txhua tus:

Bitumen (sib xyaw: specaltene thiab cob) Cov quav dev thiab lim, ib qho kev sib xyaw los ntawm cov neeg sawv cev sib xyaw los ua cov tshuaj tiv thaiv kab mob siab; Nqa cov tshuaj ntsuam ntawm cov hnoos qeev yas (nyias, mos, cov nplaum ntawm cov dej kub, thiab cov neeg nyoos ntawm cov txheej txheem dej lossis dej npau npau;
Thaum tsim nyog, peb tuaj yeem siv bittumen (sib xyaw: asphalent tuab daim ntawv, nyias, mos, peb tuaj yeem siv cov cai xis nyob ua ke, lossis peb tuaj yeem siv cov Caas pob zeb ua haujlwm tsis muaj hnub nyoog. Nqa tawm cov kab rov tav kev ruaj ntseg (kev hais tawm: khov kho; tsis muaj kev hloov pauv ntawm cov kub ua haujlwm thiab kev coj ua tau zoo ntawm kev tiv thaiv kab mob.
Nqa tawm kev laus sai (kev laus lub sij hawm luv luv lossis ntev ntev) kev kho kom sib xyaw kub asphalt (sib xyaw Kev coj ua cov dej ua haujlwm ntawm cov khoom lag luam marshall thiab impulsion cov kev xeem ntawm cov sib tov los soj ntsuam basumen (kev qhia: khov kho; tsis muaj kev hloov).
Lub ntsiab kev sim ntawm Bitumen (muaj pes tsawg leeg: asphaltene thiab cob qhia) cov khoom siv me me yog qhov no. Peb yuav tsum ua cov haujlwm zoo raws li cov lus qhia kom qhia tau nws cov yam ntxwv. Muaj ntau ntau cov tech ntsig txog bitumen meterter cov khoom siv. Yog lawm, peb yuav xaiv nws rau koj dua. Koj tab tom zoo siab txais tos kom xyuas nws tawm tam sim ntawd.
