Hauv kev tsim kho asphalt pavement, kev npaj cov khoom siv, khoom siv, thiab cov neeg ua haujlwm yog qhov tseem ceeb rau kev ua tiav ntawm qhov project. Txawm tias muaj kev npaj tsim ua tiav, cov khoom siv tsis zoo, cov tshuab asphalt tsis txaus, lossis cov neeg ua haujlwm tsis txaus tuaj yeem ua rau qhov project qeeb, teeb meem zoo, lossis rov ua haujlwm dua. Cov phiaj xwm thoob ntiaj teb qhia tau hais tias kev npaj txhij txhua yog txuas nrog rau qhov kawg ntawm txoj kev taug kev zoo. Tshooj lus no suav nrog peb yam ntawm kev npaj: cov khoom siv, khoom siv hauv kev, thiab kev ua haujlwm.
Cov ntaub ntawv yog nyob rau hauv lub plawv ntawm asphalt pavement kev tsim kho, xws li asphalt, aggregates, mineral fillers, thiab auxiliary additives. Qhov zoo ntawm cov ntaub ntawv ncaj qha cuam tshuam rau kev ua tau zoo ntawm kev sib tov, kev tsim kho, thiab kev ua haujlwm ntev. Tag nrho cov ntaub ntawv yuav tsum tau soj ntsuam nruj me ntsis, kuaj, thiab npaj npaj ua ntej kev tsim kho.
Asphalt pavement siv tshuab yog lub hauv paus ntawm kev tsim kho kev tsim khoom. Los ntawm cov khoom siv raw khoom sib xyaw, kev thauj mus los, thiab paving mus rau compaction, txhua theem tso siab rau kev sib koom tes txuas ntxiv ntawm cov cuab yeej siv tshuab. Kev npaj cov cuab yeej muaj xws li kev tshuaj xyuas cov tshuab, kev sib txuam muaj peev xwm, kev calibration, kev ntsuam xyuas kev nyab xeeb, thiab kev cob qhia neeg ua haujlwm. Ntiaj teb no txoj kev engineering tej yaam num ua raws li lub hauv paus ntsiab lus: "Kev npaj khoom siv=kev ruaj ntseg zoo."
High- kev tsim kho txoj kev zoo yuav tsum muaj ib pab neeg ua haujlwm tau zoo. Kev faib cov neeg ua haujlwm yuav tsum npog txhua yam, suav nrog kev siv thev naus laus zis, kev ua haujlwm, kev tswj kom zoo, thiab kev nyab xeeb, kom ntseeg tau tias kev ua tiav ntawm txoj haujlwm ua haujlwm tau zoo.
