Cov kev qhia tshwj xeeb rau kev tsim kho asphalt pavement xa mus rau cov qauv txheej txheem thiab cov lus qhia tshwj xeeb uas yuav tsum tau ua raws li kev tsim kho asphalt pavement. Raws li tus qauv kev tsim kho, nws yuav tswj tau qhov zoo ntawm qhov project thiab xyuas kom meej cov txiaj ntsig ntawm qhov project, uas yog ib qho tseem ceeb ntawm cov qauv hauv paus rau kev tsim kho thiab kev tshuaj xyuas engineering.

Kev tswj xyuas kev ua tau zoo rau asphalt pavement feem ntau suav nrog cov hauv qab no:
1. Tsim theem
Nyob rau hauv theem tsim, nws yog ib qho tsim nyog los ntsuas thiab xam qhov chaw, linearity, elevation, txoj kab nqes, thiab sab nqes hav ntawm txoj kev nto kom ntseeg tau qhov tseeb ntawm cov ntaub ntawv tsim. Nyob rau tib lub sijhawm, nws tseem yuav tsum xav txog qhov cuam tshuam ntawm huab cua, ntim tsheb, struts thiab lwm yam ntawm txoj kev tsim kho, thiab tsim cov phiaj xwm kev tsim kho.

2. Kev tsim kho subgrade
Lub subgrade yog lub hauv paus ntawm asphalt pavement, thiab nws lub zog, stability thiab smoothness yuav tsum tau guaranteed.
Cov kev siv feem ntau yog sau thiab khawb. Cov khoom ntim yog feem ntau cov txiv qaub av, gravel, thiab lwm yam, thiab cov khoom siv excavation feem ntau yog benign av lossis xuab zeb av. Thaum lub sij hawm tsim kho, yuav tsum tau them nyiaj mloog mus rau kev tswj qhov siab thiab dav ntawm lub subgrade raws li tus tsim elevation los xyuas kom meej lub compactness thiab flatness ntawm lub subgrade.

3. Kev tsim kho hauv paus
Lub hauv paus txheej yog cov txheej txheem thauj khoom ntawm asphalt pavement, uas muaj kev cuam tshuam zoo rau lub neej kev pab cuam thiab tsav kev nplij siab ntawm txoj kev pavement. Cov ntaub ntawv siv feem ntau yog graded crushed pob zeb, av nkos pob zeb, thiab lwm yam. Thaum lub sij hawm tsim kho, yuav tsum tau them nyiaj mloog mus rau kev tsim kho raws li tus qauv tsim tsa thiab thickness los xyuas kom meej lub zog thiab flatness ntawm lub hauv paus.

4. Kev tsim cov asphalt sib tov
Asphalt sib tov yog cov khoom tseem ceeb ntawm asphalt pavement, uas muaj kev cuam tshuam zoo rau kev ua haujlwm zoo thiab kev pab cuam lub neej ntawm pavement. Feem ntau siv cov ntaub ntawv asphalt xws li thee tar pitch, shale pitch, petroleum pitch, etc. Asphalt mixing xav tau asphalt mixing cog kom tiav. Thaum lub sijhawm tsim khoom, yuav tsum ua tib zoo xaiv cov ntaub ntawv asphalt uas tsim nyog, thiab tswj qhov sib xyaw thiab cov cua kub ntawm asphalt kom ntseeg tau tias cov khoom sib xyaw asphalt ua tau raws li cov qauv tsim.

5. Txoj kev tsim kho
Pavement kev tsim kho yog txheej txheem kawg ntawm asphalt pavement, uas muaj kev cuam tshuam zoo rau cov tsos, zoo thiab kev pab cuam lub neej ntawm pavement. Thaum lub sij hawm tsim kho, yuav tsum tau them nyiaj mloog mus rau kev tsim kho raws li tus tsim tsa thiab thickness los xyuas kom meej lub flatness thiab transverse txoj kab nqes ntawm txoj kev nto. Thaum lub sij hawm tsim kho, nws tseem yuav tsum tau ua tib zoo saib xyuas kom tsis txhob muaj teeb meem xws li plua plav thiab lub tsheb spilling, thiaj li yuav xyuas kom meej tias ib puag ncig ntawm qhov chaw tsim kho yog huv si thiab huv si.

Henan Sinoroader Heavy Industry Corporation yog ib lub tuam txhab suav tshwj xeeb hauv kev tsim cov asphalt sib xyaw cov nroj tsuag, Yog tias koj muaj cov khoom siv asphalt xav tau, tawm tswv yim lossis lus ntiag tug rau peb, thiab tos ntsoov yuav cuam tshuam nrog koj.
