Nrog rau kev txhawb nqa ntawm cov qauv ntawm kev tiv thaiv ib puag ncig thiab kev tiv thaiv kev siv hluav taws xob, kev tiv thaiv ib puag ncig los ua kev sib xyaw ntawm cov khoom lag luam sib xyaw. Cov cuab yeej siv zoo li cas tuaj yeem hu tau ib puag ncig phooj ywg zoo siab qhob ua ke? Dab tsi yog qhov tseem ceeb uas yuav tsum tau ua tau?

Ua ntej tshaj plaws, raws li ib puag ncig phooj ywg asphalt qhob kev sib xyaw ua ke ua ke ntawm kev siv hluav taws xob tsawg dua thaum siv. Uas yog hais, nyob rau hauv cov kev mob ntawm tib kom muaj nuj nqis thiab zoo, tsawg zog tau noj thaum lub sij hawm ua haujlwm, suav nrog ntau yam peev txheej xws li dej thiab hluav taws xob.
Qhov thib ob, ib puag ncig phooj ywg asphalt qhob feem tsuas yog yuav tsum tau ua tiav cov tshuaj tiv thaiv cov pa roj ntau dua, yog li kom tau raws li cov khoom siv roj carbon ntau dua.
Tsis tas li ntawd, tsuas yog cov uas tuaj yeem tswj cov pa phem tsim tawm thiab txo qhov kev puas tsuaj ncaj ncees rau cov pa phem ua los ntawm kev ua haujlwm exphaltly asphalt qhob noom. Kuj tseem muaj rau nws cov kev npaj cog, txawm tias nws yog qhov chaw ua haujlwm ntawm cov roj dej thiab cov roj pov, nws yuav tsum tsim nyog.
Feem ntau, ib puag ncig phooj ywg zoo li kev sib xyaw ua ke, zoo li cov chaw nres tsheb sib xyaw ua ke, hom sib deev thiab txuas ntxiv. Tab sis tsis muaj teeb meem uas tsim nyog nws yog, nws tuaj yeem sib tov thiab muab cov dej sib xyaw ua ke ntawm qhov sib xyaw sib txawv raws li cov ntsuas kub uas tsim nyog.
Tsuas yog ua tiav cov txheej txheem ua tiav ib puag ncig cov nroj tsuag uas ua kom muaj kev sib xyaw ua ke thiab cov chaw nres tsheb hauv nroog, thiab saib xyuas cov chaw nres tsheb asphalt.
