Hauv Asphalt ntau lawm, txheej txheem ntsuas kub yog qhov tseem ceeb hauv kev cog cog qoob loo thiab cov khoom ntawm cov kub sib tov. Txhawm rau kom paub meej tias lub sijhawm ntev ntawm txoj kev pavement, tus ntsuas kub yuav tsum tau saib xyuas thaum lub sijhawm sib xyaw ua haujlwm thiab thaum cov kub sib tov yog ?? thau khoom. Txhawm rau kom ntseeg tau tias qhov ntsuas kub tseem nyob hauv kev txwv tshwj xeeb thaum cov khoom siv tau xa mus rau lub tshuab tov khoom, qhov kub yog kev soj ntsuam qhov twg cov ntaub ntawv tawm ntawm lub nruas. Qhov cub tawg yog tswj tau raws li cov ntaub ntawv no. Qhov no yog vim li cas cov khoom siv rau asphalt tov kev siv pyrometers rau cov ntsuas ntsuas ntsuas thiab tswj qhov ntsuas kub.

Tsis yog qhov ntsuas kub tsis raug ntsuas los ntawm pyrometers yog ib qho tseem ceeb hauv kev tswj cov txheej txheem zoo. Firstly, pyrsometers yog qhov zoo tagnrho rau ntsuas qhov ntsuas kub ntawm cov sib tov nyob hauv lub tshuab ziab khaub ncaws kom pab tswj kom sov li ntawm asphalt sib tov. Thib ob, pyrometers tuaj yeem qhia nyob rau ntawm daim ntawv tso tawm tawm los ntsuas qhov kub ntawm cov khoom tiav thaum nws yog conveyed rau lub cia txhab.
Cov pab pawg ua txhaum muab tshuaj, kev ua tau zoo, cov cuab yeej siv tau uas muaj qhov tseeb yuav tswj tau cov pa phem ib puag ncig, tab sis nws tsis txaus siab. Peb kuj yuav tsum tau ua peb qhov zoo tshaj plaws los txhim kho cov nroj tsuag thiab cov khoom siv thiab cov khoom siv kom tau raws li cov neeg yuav khoom tshwj xeeb hauv tsev thiab txawv teb chaws.
