1. Qhia meej cov kev xav tau: Ua ntej, peb yuav tsum qhia meej txog peb cov kev xav tau thiab cov hom phiaj, xws li kev tsim khoom, hom khoom, kev xav tau zoo, thiab lwm yam.
2. Xav txog kev ua haujlwm ntawm cov cuab yeej siv: Thaum xaiv cov khoom siv, peb yuav tsum tau ua tib zoo saib xyuas nws cov kev ua tau zoo, xws li melting muaj peev xwm, cia muaj peev xwm, conveying efficiency, thiab lwm yam.
3. Ntsuas cov cuab yeej zoo: Cov khoom siv zoo yog ncaj qha ntsig txog nws lub neej kev pabcuam thiab tus nqi tu. Yog li ntawd, thaum xaiv cov khoom siv, peb yuav tsum ua qhov kev ntsuam xyuas zoo ntawm cov khoom siv, nrog rau cov khoom siv, cov txheej txheem, kev pab cuam tom qab muag, thiab lwm yam.
4. Sib piv cov nqi thiab kev ua haujlwm zoo: Nqe yog qhov tseem ceeb thaum xaiv cov khoom siv. Txawm li cas los xij, peb tsis tuaj yeem siv tus nqi tsuas yog qhov kev xaiv rau kev xaiv, tab sis yuav tsum muab cov kev ua tau zoo, kev ua tau zoo, kev pab cuam tom qab muag thiab lwm yam ntawm cov cuab yeej siv los txiav txim siab txog nws qhov txiaj ntsig zoo.
5. Xav txog kev nyab xeeb thiab kev tiv thaiv ib puag ncig: Thaum xaiv cov khoom siv asphalt, peb kuj yuav tsum xyuam xim rau nws txoj kev nyab xeeb thiab kev tiv thaiv ib puag ncig. Cov khoom siv yuav tsum muaj kev tiv thaiv kev nyab xeeb tag nrho, xws li tawg-pov thawj, hluav taws-pov thawj, thiab pov thawj pov thawj, thiab tseem yuav tsum ua kom tau raws li kev tiv thaiv ib puag ncig kom txo tau cov pa phem ntawm cov pa phem, dej khib nyiab, thiab cov khib nyiab pov tseg.
6. Xa mus rau kev soj ntsuam kev lag luam: Thaum xaiv cov khoom siv, koj tuaj yeem xa mus rau qhov kev ntsuam xyuas thiab kev tawm tswv yim hauv kev ua lag luam kom nkag siab txog kev ua tau zoo, kev ua tau zoo thiab kev pab cuam tom qab muag ntawm cov khoom siv. Qhov no pab peb nkag siab txog cov cuab yeej siv tau ntau dua thiab zam kev xaiv qhov muag tsis pom.
