Cov chaw tsim khoom nkag nrog koj ua haujlwm ntawm asphalt melting khoom, uas yog tsuas yog siv los ua kom sov thiab yaj asphalt kom tau raws li kev tsim kho lossis siv. Cov cuab yeej siv hluav taws xob feem ntau siv cua sov lossis roj cua sov, thiab muaj cov yam ntxwv txuag hluav taws xob, ib puag ncig kev tiv thaiv thiab lwm yam. Kev siv cov khoom siv asphalt tuaj yeem txhim kho kev tsim kho kev tsim kho, txo kev noj hluav taws xob, thiab tib lub sijhawm ua kom zoo. Ib qho ntxiv, cov cuab yeej zoo no tseem tuaj yeem siv rau hauv kev txij nkawm, kev kho lub plawv ntawm kev ua teb thiab lwm thaj teb, thiab muaj cov ntawv thov kev thov ua tiav.

Asphalt melting khoom muaj cov txiaj ntsig hauv qab no:
1. Siv cov thev naus laus zis tshuab cua txias, nws tuaj yeem yaj asphalt sai thiab zoo thaum txuag lub zog.
2. Cov khoom siv tau ua los ntawm cov ntaub ntawv thiab cov txheej txheem uas muaj kev ruaj khov zoo thiab kev ntseeg tau thiab muaj peev xwm ua haujlwm stably rau lub sijhawm ntev.
3. Yooj yim rau kev khiav lag luam: Cov khoom siv muaj cov kev tswj hwm zoo, uas yog qhov yooj yim ua haujlwm, tswj thiab tswj hwm.
4. Kev tiv thaiv ib puag ncig thiab kev nyab xeeb: cov cuab yeej siv tau ua tiav cov roj av tiv thaiv kev khib nyiab, dej khib nyiab thiab cov suab nrov thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm.
5. Cov khoom siv dav dav: cov khoom siv tau haum rau ntau hom kev phem asphalt, txias sib tov asphalt thiab lwm yam, thiab muaj ntau cov kev siv.
