Nti foob yog siv cov khoom siv tshwj xeeb, kom kis tau cov pob zeb asched Nws yog tsuas yog siv los ua txheej txheej saum npoo av, thiab kuj tseem siv tau rau txheej txheej ntawm cov khoom qis. Qhov loj tshaj plaws kom zoo ntawm synchronous spip foob cov tshuab yog cov khoom siv sib txuas ntawm txoj kev sib tsoo uas tsis muaj kev sib xyaw ua ke yam tsis muaj kev ua kom zoo dua qub, yog li ua kom lub pob zeb ua kom zoo dua li cov khoom sib tsoo thiab cov pob zeb.

Nti foob muaj cov kev ua tau zoo los ntawm kev ua tau zoo thiab tiv thaiv kev ua tiav saum npoo av, thiab tuaj yeem hloov kho me me, rutting, subsidence thiab lwm yam kab mob. Nws yog tsuas yog siv rau kev tiv thaiv thiab kho kev kho ntawm txoj kev, nrog rau txhawm rau txhim kho cov kev tawm tsam qib siab.
Slurrry foob yog txheej nyias nyias los ntawm cov khoom siv txhua yam tsim kho kom zoo rau hauv cov kab mob asphalt, ntxhib thiab lwm yam (xis mas, Txij li cov emulsified asphalt tov yog nyias thiab nyias muaj kev puas tsuaj, feem ntau tsawg dua 3 cm, feem ntau tsawg dua 3 cm, thiab ua si-resistant thiab txhim kho txoj haujlwm ntawm txoj kev saum npoo. Tom qab cov hlais slurry yog thov mus rau txoj kev ntxhib ib sab ntawm cov khoom siv nyiaj asphalt, thiab nws tuaj yeem ua rau txheej txheem kev coj ua.
