Chaw nres tsheb sib tov (tseem hu ua chaw nres tsheb sib tov, chaw nres tsheb sib xyaw) yog lub ntsiab lus dav dav rau cov tshuab loj siv rau kev tsim vaj tsev sib xyaw hauv kev tsim kho. Cov nroj tsuag sib xyaw yog subdivided rau hauv pob zeb sib xyaw cov nroj tsuag, stabilized av mixing nroj tsuag, thiab dej stabilized mixing nroj tsuag. Qhov chaw sib tov yog siv rau cov av ruaj khov ntawm cov qib highways, txoj kev hauv nroog, squares, thiab tshav dav hlau. Nws tuaj yeem txuas ntxiv sib xyaw thiab tsim cov qib sib txawv ntawm cov txiv qaub-stabilized gravel, txiv qaub-stabilized av, thiab cov khoom pov tseg cov khoom seem stabilized av tiav. Qhov chaw ruaj khov av sib xyaw yuav tsum tau muab ntxuav tom qab nws tau siv rau lub sijhawm. Yuav ua li cas yuav tsum tau ntxuav cov av stabilized? Raws li ib tug stabilized av mixing chaw tsim tshuaj paus, peb yuav kawm nrog koj hnub no.
1. Thaum lub caij txias heev, tom qab ua haujlwm tiav lawm, siv dej los ntxuav cov av ruaj khov sib xyaw ntawm qhov chaw nres tsheb thiab tso cov dej hauv lub twj tso kua mis, lub tank dej, thiab cov kav dej kom tsis txhob muaj lub twj tso kua mis, lub tank dej, thiab cov kav dej. los ntawm kev puas tsuaj los ntawm khov.
2. Nws yog txwv tsis pub siv lub sledgehammer tshem tawm cov pob zeb uas muaj nyob rau hauv lub raj ntawm qhov chaw ruaj khov av sib xyaw, tsuas yog siv lub chisel xwb.
3. Ua ntej pib qhov chaw ruaj khov ntawm cov av sib tov, xyuas seb cov tswj tau zoo li cas. Tom qab kev ua haujlwm raug tso tseg, ncuav dej thiab pob zeb rau hauv lub nruas sib tov rau 10-15 feeb rau kev ntxuav, thiab tom qab ntawd tshem tawm cov dej thiab pob zeb. Yog tias tus neeg teb xov tooj xav tau nkag mus rau hauv lub nruas sib tov rau kev ntxuav, ntxiv rau kev txiav tawm lub hwj chim thiab tshem tawm lub fuse, lub thawv hloov yuav tsum tau muab xauv.
4. qhov chaw ruaj khov ntawm cov av sib xyaw yuav tsum tsis tu ncua ua haujlwm tu thiab tu cov khoom uas tau teev tseg hauv cov cai tswj xyuas, xws li ntxuav, lubricating, thiab refueling.
