Raws li kev txhim kho lub zog nyiaj txiag, Tuam Tshoj tau tswj hwm qhov kev loj hlob ntawm kev siv hluav taws xob hauv tsev. Raws li ib qho ntawm txoj hauv kev tseem ceeb los txuas rau hauv nroog thiab cov cheeb tsam nyob deb nroog thiab sab nraud, kev thauj sab nraud, kev thauj mus los hauv tsev kuj tau ua rau muaj kev nce qib tam sim no.

Asphalt txoj kev kev ua dej txias kho cov khoom noj yog ib qho khoom siv ntxhia (ancerate) sib xyaw ua ke thiab muaj ntau yam zoo tshaj plaws thiab muaj ntau yam kev thov cov xwm txheej.

Hauv ntau thaj teb sib txawv, cov cai rau kev tiv thaiv ib puag ncig yog nruj heev tam sim no. Yuav ua li cas thiaj tuaj yeem sib xyaw ua ke sib tw tau raws li kev tiv thaiv ib puag ncig ib puag ncig? Qhov no tau dhau los ua kev txhawj xeeb rau ntau lub tuam txhab chaw nres tsheb sib tov. Yog tias cov tuam txhab tsim khoom xws li asphalt sib xyaw ua ke rau kev tiv thaiv ib puag ncig, nws yuav tsis tsuas yog txo qhov kev cuam tshuam ntawm kev muaj kuab paug ib puag ncig. Yog li, ib puag ncig kev tiv thaiv kev tiv thaiv tau dhau los ua ib qho ntawm cov haujlwm tseem ceeb ntawm kev sib xyaw.

Asphalt sib xyaw ua ke tau tsim tsa raws qee cov txheej txheem, uas tsis tuaj yeem tsuas yog tias lub chaw nres tsheb asphalt sib tov tsis puas. Txawm hais tias kev tsim cov ntsiab lus tseem ceeb, cov txuj ci tseem ceeb ntawm asphalt sib tov yuav tsum tau ua.

Hauv cov txheej txheem ntau lawm ntawm emulsified asphalt, emulsification fineness yog qhov tseem ceeb ntawm kev ua tau zoo thiab kev thov ntawm emulsified asphalt. Kab lus no yuav tshawb txog qhov tseem ceeb ntawm emulsification zoo heev thiab yuav ua li cas tswj emulsiful fineness los ntawm emulsified asphalt khoom.

Hauv cov txheej txheem ntau lawm ntawm General emulsified ashrhalt, lub qhov hluav taws xob asphalt yog feem ntau nyob ib puag ncig ayhalt yuav tsum nyob saud 95 ℃. Yuav ua li cas ua kom zoo siv ntawm tshav kub ntawm emulsified asphalt khoom?
