Los ntawm kev txhim kho, qhov precision ntawm txhua txoj haujlwm sib khi ntawm cov khoom siv neeg kho tshuab yog tau lav kom ntau li ntau tau, yog li ntawd cov pa luam yeeb tuaj yeem txo.

Ib qho ntxiv, nws tseem yuav tsum tau them sai sai rau cov ntsiab lus tseem ceeb ntawm kev txhim kho cov khoom lag luam hauv chaw nres tsheb, thiab xyuam xim rau kev tswj cov pa luam yeeb tawm ntawm txhua theem.
Cua ceev cov plua plav tawm yog ib txoj hauv kev los nrog cov pa luam yeeb hauv cov chaw nres tsheb asphalt sib tov. Cov plua av nqus tau tsuas yog siv rau cov plua plav tshem tawm, tab sis cov khoom siv tshem tawm cov plua plav qub tsuas tuaj yeem tsuas yog cov pa luam yeeb loj dua. Cov kev txhim kho cua nrawm nrawm nrawm nrawm, uas ua ke ntau cov plua plav ntawm ntau qhov sib txawv, tuaj yeem muab cov tshuaj sib txawv rau cov pa luam yeeb ntawm cov sib txawv.
Ntxiv rau cua ceev plua plav tshem tawm cov plua plav tshem tawm thiab cov cuab yeej txhim kho kev sib xyaw ua ke kuj tseem siv cov plua plav ntub thiab cov hnab ntub dej tshem tawm. Ntub dej ntub dej tshem tawm muaj qib siab dua ntawm cov plua plav tshem tawm thiab tuaj yeem tshem cov plua plav tsim thaum lub sijhawm ua ke.
