Thaum lub sij hawm kev siv txheej txheem kev ua haujlwm ntawm kev ua ke engineering, vim muaj kev nyuaj ntawm lub engineering li cas, muaj ntau ntau yam teeb meem uas yuav tshwm sim. Ntawm lawv, cov chaw nres tsheb Asphalt yog cov khoom tseem ceeb hauv txoj haujlwm no, yog li nws yuav tsum tau them nyiaj kom txaus rau. Cia peb saib cov teeb meem uas koj yuav ntsib.
Raws li kev paub ntawm cov rooj plaub kev tsim chaw nyob hauv peb lub teb chaws ntau xyoo, kev ua haujlwm ntawm asphalt sib xyaw ua ke yuav raug cuam tshuam los ntawm ntau yam. Txhawm rau txhawb qhov zoo ntawm asphalt tej yaam num, peb yuav soj ntsuam nws raws li cov teeb meem ntawm cov teeb meem thaum lub sijhawm tsim kho tau muab rau qee cov kev ua tau zoo.

Piv txwv li, ib qho teeb meem nquag thaum lub sijhawm tsim kho cov cuab yeej yog cov teeb meem tawm. Vim tias qhov teeb meem no yuav cuam tshuam ncaj qha rau lub sijhawm tsim kho ntawm txoj haujlwm thiab ntau lwm yam kev xam pom, nws tau pom tias yuav muaj cov khoom txaus ntshai ntawm cov khoom siv asphalt sib tov. Tam sim no kuv yuav muab nws qhia rau koj.
1. Qhov sib piv ntawm cov ntaub ntawv raw tsis tsim nyog. Cov ntaub ntawv nyoos yog thawj kauj ruam hauv kev tsim khoom. Yog hais tias tus piv ntawm cov ntaub ntawv raw yog tsis tsim nyog, nws yuav cuam tshuam kev tsim kho txuas ntxiv thiab ua rau muaj teeb meem xws li kev txo qis hauv kev tsim kho. Lub hom phiaj sib tov sib piv yog tswj cov feem ntawm cov khoom siv txias ntawm cov xuab zeb txias ntawm cov xuab zeb thiab gravel, thiab yuav tsum tau hloov kho raws li qhov teeb meem tiag tiag thaum lub sijhawm tsim khoom. Yog tias muaj teeb meem nrog kev sib koom tes muaj kev sib koom tes, yuav tsum tau kho kom tsim nyog yuav tsum ua kom muaj cov zis ntawm asphalt sib tov chaw nres tsheb.
2. Cov roj cua tshuab hluav taws xob tsis txaus. Txhawm rau kom ua tau zoo, qhov zoo ntawm cov roj sib txuas hluav taws yuav tsum tau xaiv thiab siv raws li cov qauv txheej txheem. Txwv tsis pub, yog tias koj xaiv los hlawv cov diesel, cov roj diesel lossis hnyav rau cov khoom cua kub, nws yuav ua rau cov khoom siv dej sov, ua rau cov khoom lag luam li asphalt sib tov.
3. Qhov ntsuas kub yog qhov tsis sib xws. Raws li peb txhua tus paub, qhov kub ntawm cov khoom xa tawm yuav muaj qhov cuam tshuam tseem ceeb rau cov khoom siv zoo. Yog tias qhov kub thiab txias dhau lossis qis dhau, cov ntaub ntawv no yuav tsis siv ib txwm ua thiab ua pov tseg. Qhov no yuav tsis tsuas yog nkim cov nqi tsim khoom ntawm cov asphalt sib tov cog, tab sis kuj cuam tshuam nws cov khoom tsim ntau lawm.
