/4the siv cov hloov kho aspifify los hloov aspify li ntiaj teb thoob ntiaj teb. Nyob rau hauv nruab nrab-xyoo pua puv 19, txoj kev vulcanization tau siv los txo cov kev nkag mus aspetration asphalt thiab nce cov khoom muag muag taw tes. Txoj kev txhim kho ntawm kev hloov kho asphalt hauv 50 xyoo dhau los tau kwv yees li ntawm plaub theem.

Ntau tus neeg siv uas siv emulsified asphalt tsis to taub vim li cas emulsified asphalt yuav tsum tau hais tawm, tsis yog nws siv yog. Yog li ntawd, tus editor ntawm emulsified Asphalt Chaw Tsim Tshuaj Astralt xav kom paub txog lub sijhawm no los piav qhia txog cov kev paub txog emulsified evulsification.

Raws li peb txhua tus paub, micro-surfacing thiab slurry sealing yog ob tus neeg sib txawv ntawm kev siv, yog li cov neeg siv kev tiv thaiv kev tiv thaiv zoo ib yam li koj qhia koj qhov sib txawv ntawm ob.

Asphalt yog cov kua roj uas muaj paug nrog cov npoo av uas muaj ntxhiab tsw zoo nkauj thiab yog soluble hauv carbon disulfide (ua kua kub-daj, ua kua daj).

2. Kev tiv thaiv me me li asphalt yuav tsum yog kev tiv thaiv theem nrab. Tom qab lub zog tau muab ua ntej mus ua haujlwm, lawv yuav tsum tau tshuaj xyuas kom zoo. Tom qab ib qho kev sim ua tsis muaj dab tsi, lawv pom tias tsim nyog ua ntej lawv tuaj yeem siv. Thaum lub sijhawm mus so haujlwm, nws yuav tsum tau txheeb xyuas seb puas muaj nws lub nruas sib tov yog qhov tsim nyog. Nyob rau hauv ib txwm muaj xwm txheej, qhov ceev ntawm lub tsheb khoob yog nrawm dua li tias ntawm lub tsheb hnyav (tom qab chaw thau khoom) los ntawm 2 txog 3 lub revolutions. Yog tias qhov sib txawv yog qhov loj, qhov sib piv ntawm lub log txav thiab lub rooj sib kis tus kab mob yuav tsum tau hloov kho. ?
