Nyob rau hauv ib txheej txheej pavement, txij hauv qab mus rau sab saum toj muaj cov khoom siv cementing, aggregates, thiab cov ntaub ntawv cementitious. Cov txheej txheem ob txheej txheej txheej yog ntau txoj, muab faib ua 5 txheej, hauv qab mus rau sab saum toj, cov khoom siv cementing, aggregate, cementing material, aggregate, cementing material. Txoj kev twg tsim nyog nyob ntawm txoj kev.
Lub luag haujlwm ntawm Lub Tsev Haujlwm Jingbiao feem ntau yog tshwm sim hauv cov hauv qab no. Ua ntej, nws tuaj yeem txhim kho cov dej tsis zoo thiab tawg-tiv taus ntawm txoj kev nto. Los ntawm kev tso cov binders thiab cov sib sau ua ke, kev ua tiav tuaj yeem ua rau txoj kev denser thiab txo cov dej nkag, yog li txo qhov kev pheej hmoo ntawm txoj kev tawg. Thib ob, kev kho kom zoo ntawm qhov chaw tuaj yeem txhim kho qhov kev ua haujlwm tiv thaiv kev ua haujlwm ntawm txoj kev nto. Vim yog kev xaiv ntawm kev sib sau ua ke thiab kev ua kom zoo ntawm cov txheej txheem paving, qhov zoo ntawm txoj kev pavement tuaj yeem muab kev sib txhuam zoo dua thiab txo cov kev pheej hmoo ntawm kev tsheb. Tsis tas li ntawd, kev kho kom zoo ntawm qhov chaw tuaj yeem ua rau qeeb ntawm qhov tshwm sim ntawm asphalt pavement kab mob.

Hauv kev siv cov tswv yim, kev siv thev naus laus zis zoo tshaj plaws muaj qhov zoo ntawm kev tsim qauv sai, kev tsim kho yooj yim, thiab kev tiv thaiv ib puag ncig. Los ntawm kev xaiv cov khoom siv cementitious thiab cov khoom sib sau ua ke, cov cuab yeej kho kom zoo nkauj tuaj yeem ua tiav kev tu cov pavement hauv lub sijhawm luv luv thiab txo cov kev cuam tshuam ntawm kev khiav tsheb. Nyob rau tib lub sijhawm, cov cuab yeej tsim kho nrog cov thev naus laus zis thev naus laus zis zoo tuaj yeem ua tiav cov khoom sib xyaw ua ke thiab cov khoom siv cementitious kom ntseeg tau tias kev tsim kho zoo. Tsis tas li ntawd, cov khoom siv hauv kev kho mob saum npoo av muaj kev ua haujlwm zoo ib puag ncig thiab ua raws li kev txhim kho ntawm kev thauj mus los ntsuab niaj hnub.
