qhov ntim ntawm lub taub hau uas muaj kev sib cais (8 sau lo lus nug) Kev Pabcuam Lub Neej. Qhov kev rho tawm siv tshuab tau txais txoj siv tawv thiab hloov pauv thiab hloov pauv ntawm cov kev tswj hwm thiab tswj hwm, uas yog ib puag ncig phooj ywg thiab txuag hluav taws xob.

Thaum siv cov khoom siv asphalt, cov kev cai ua ke suav nrog cov khoom uas yuav tsum tau ua thiab cov khoom txwv. Txawm hais tias qhov twg yog qhov zoo sib xws nrog kev siv cov txiaj ntsig ntawm cov khoom siv. Tus editor tau teev qee yam uas tsis tso cai rau cov khoom siv asphalt sib tov, tsuas yog khaws cia rau hauv lub siab.

Cov khoom siv asphalt tsim los ntawm asphalt tov khoom siv ntau yam, tab sis nag lossis daus tshwm sim thaum cia. Nov puas yog? Dab tsi ua rau qhov tshwm sim no?

Muaj ob txoj kev hloov kho lub ntsiab rau cov tshuab hluav taws kub asphalt tso tsheb hlau luam: kev sib xyaw sab nraud thiab txoj kev sib xyaw sab nraud. Txoj kev sib xyaw sab nraud yog los ua ntej npaj cov roj thermal dechalt rau cov neeg Jiangx cov hluav taws xob tank, thiab sib tov thiab do kom nws.

Muaj ob txoj kev hloov kho ntawm txoj kev hloov kho rau emulsified asphalt khoom: sib xyaw sab nraud thiab txoj kev sib xyaw ua ke. Cov txheej txheem sab nraud yog thawj zaug ua ib qho yooj yim emulsx daws rau cov khoom siv ayhalified rau cov khoom siv uas aspuls emultified, thiab sib tov thiab do kom nws.

Asphalt kis tus kab hluav taws xob yog ib hom dub kev siv tshuab. Nws yog cov khoom siv tseem ceeb hauv kev tsim kho ntawm txoj kev loj, txoj kev hauv nroog, tshav dav hlau thiab chaw nres nkoj cov chaw nres nkoj. Cov khoom siv no feem ntau yog siv los tshuaj tsuag ntau hom kev siv asphalt ntawm txoj kev tsim kho ntawm cov txheej txheem sib txawv ntawm cov txheej txheem asphalt, thiab lwm yam kis tau sib kis cov tsheb thauj khoom ntawm kev ua lag luam tsis txaus siab. Yuav muaj kev faib cov kab rov tav tsis sib haum. Ib qho kev tshwm sim raug ntawm cov kab rov tav tsis sib haum yog kab rov tav kab rov tav. Nyob rau lub sijhawm no, qee yam kev ntsuas tuaj yeem nqa mus ua kom zoo ua kom zoo rau cov khaub ncaws tom qab asphalt kis.
