Qhov tseem ceeb ntawm Asphalt Mixture Regeneration

Kev rov ua dua tshiab ntawm asphalt sib tov yog qhov tseem ceeb rau kev txuag cov khoom siv tseem ceeb hauv kev tsim kho, tshwj xeeb tshaj yog cov khoom siv roj av uas tsis yog rov tsim dua tshiab. Txij li thaum asphalt yog cov khoom siv roj av, nws qhov muaj tsawg tsawg ua rau kev txuag thiab rov siv cov tswv yim tsim nyog. Los ntawm kev siv thev naus laus zis, cov ntaub ntawv qub asphalt pavement tuaj yeem rov qab siv dua, txo qhov kev xav tau ntawm cov ntaub ntawv tshiab, yog li ncua kev pab cuam lub neej ntawm txoj kev thiab txo tus nqi ntawm kev tsim kho tshiab.

Kev siv cov khoom siv rov ua dua asphalt tsis tsuas yog txuag lub zog thiab txo cov nqi tab sis kuj txo qis cov pa phem rau ib puag ncig ib puag ncig. Nyob rau hauv cov txheej txheem rov tsim dua tshiab, los ntawm kev ntxiv asphalt tshiab thiab sib sau ua ke, qhov kev ua tau zoo ntawm cov qub sib tov tuaj yeem rov qab los, yog li txo cov pa phem ib puag ncig. Tsis tas li ntawd, kev siv cov thev naus laus zis rov ua dua txo cov khib nyiab xa mus rau qhov chaw pov tseg thiab txo cov kev ntxhov siab ntawm cov peev txheej av.

Kev rov ua dua ntawm cov khib nyiab asphalt sib tov tuaj yeem txhim kho qhov ruaj khov thiab ua haujlwm ntev ntawm kev pavement. Regenerated pavement muaj kev ruaj ntseg zoo dua li pavement tsim nrog cov ntaub ntawv tshiab nkaus. Qhov kev txhim kho no yog vim cov ntaub ntawv tshiab thiab asphalt ntxiv thaum lub sij hawm tsim kho, uas pab kho thiab txhim kho cov txheej txheem ntawm cov pavement.

Kev siv cov khoom siv rov ua dua asphalt muab cov txiaj ntsig tseem ceeb ntawm kev sib raug zoo thiab kev lag luam. Los ntawm kev rov siv cov bitumen thiab cov khoom sib sau ua ke, kev siv hluav taws xob tau txo qis, nrog rau cov nqi. Tsis tas li ntawd, rov siv cov ntaub ntawv qub yuav pab kom tsis txhob muaj kev ua qias tuaj rau ib puag ncig ib puag ncig, ua tiav kev txuag nqi thiab kev tiv thaiv ib puag ncig.

Piv txwv li, kev rov tsim dua tshiab ntawm asphalt sib tov tsis yog tsuas yog ib qho tseem ceeb rau kev txuag cov peev txheej thiab kev tiv thaiv ib puag ncig, tab sis nws kuj tseem txhim kho kev ua haujlwm thiab kev lag luam kev lag luam ntawm txoj kev, ua rau txoj kev siv tshuab tsim nyog txhawb nqa.
