Lub dai pob zeb ua haujlwm Spring yog cov khoom lag luam tshiab uas peb lub tuam txhab tsim kho thiab txhim kho raws li cov pob zeb pob zeb tuaj yeem siv rau kev ua lag luam. Tom qab lub tshuab tau tsim tawm ntawm kev ua lag luam, nws tau txais cov lus teb zoo ntawm cov neeg siv.

Muaj ntau ntau hom emulsion bitumen (muaj pes tsawg leeg: asphalene thiab cob cov khoom siv. Emulsion bitumen (muaj pes tsawg leeg: cov khoom lag luam asphaltene thiab cov khoom lag luam sib txawv, thiab txuas ntxiv rau ntau hom emulsion bitumen cog?

Bitumen (sib xyaw: Asphaltene thiab Resin) Tank tsim cov peev txheej tau tsom mus rau kev tsom xam ntawm peb cov backing (sib xyaw: asphaltene thiab cob) tso tsheb hlau luam. Asphaltene thiab cob cov tais diav) tso tsheb hlau luam, cia peb cov neeg ua haujlwm piav qhia rau koj. Kuv ntseeg tias nws yuav pab tau rau koj kom nkag siab cov khoom.

Raws li qhov tseem ceeb ntawm tag nrho asphalt sib tov cog, tsim ntawm kev tswj hwm cov txheej txheem tau qhia rau koj. Ob tshooj tom ntej yog hais txog nws cov kev saib xyuas txhua hnub. Tsis txhob quav ntsej txog qhov no. Kev txij nkawm zoo tseem yuav pab tswj hwm txoj haujlwm tswj hwm, yog li txhawb kev siv asphalt tov tsob nroj.

Asphalt kis tau tsheb thauj khoom yuav tsum kuaj xyuas nws cov kev tsav tsheb khiav tawm thaum ua kom lub teeb liab asphalt rau tus maub los txiav txim siab txog kev sib kis ntawm asphalt kis. Thaum lub nrawm nrawm yog qhov siab, tus maub los tswj cov dej so ntswg zoo li no, thiab thaum cov maub los tswj cov txheej txheem Asphalt, thiab cov maub los tswj kev tsim kho Asphalt Plephalt Permable permable permable permable permable permable permable permable permable permable permable permable permable permable permable permable permable permable permye.

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