Txoj kev siv tshuab, suav nrog pavers, rollers, qib, thiab tshuab milling, yog cov cuab yeej tseem ceeb rau kev tsim kho thiab tu. Nws cov khoom ua haujlwm yog nyob rau hauv qhov kev sib cuag nrog cov ntaub ntawv nyuaj xws li asphalt, pob zeb, thiab pob zeb, ntsib kev sib txhuam thiab kev cuam tshuam. Piv txwv li, paver screeds yuav tsum tau compact thiab qib asphalt ntawm qhov kub thiab txias, ua rau lawv hnav thiab deformation; cov menyuam vibratory log yuav tsum tiv taus hnyav dov, ua rau ntog qaug zog; grader scrapers yuav tsum tau theem hauv av, ua rau lawv yooj yim dulled los ntawm gravel; thiab milling tshuab cutters yuav tsum tau txiav cov qub txoj kev nto, ua rau tsis tshua muaj ceev ceev. Baohua hnav-resistant steel rau txoj kev siv tshuab muab cov kev daws teeb meem sib txawv raws li kev ua haujlwm ntawm kev siv tshuab.
Thaum siv hauv paver screeds, nws qhov siab - kub hnav tsis kam thiab siab - qhov kub thiab txias kom ntseeg tau tias cov screed tuav nws txoj kev tiaj tus mus ntev, txhim kho txoj kev paving zoo. Thaum siv nyob rau hauv vibratory rollers, nws lub zog siab thiab hnav tsis kam ua kom ntev lub neej kev pab cuam lub neej thiab txo txij nkawm zaus. Thaum siv nyob rau hauv grader scrapers, nws cov hardness siab ua rau cov scraper ntse thiab txhim kho qhov ua tau zoo. Thaum siv nyob rau hauv milling tshuab cutters, nws zoo heev hnav tsis kam txo cutter hnav thiab txhim kho milling efficiency. Hauv txoj kev loj thiab kev tsim kho hauv nroog thiab kev saib xyuas, kev tsim kho tshuab siv Baohua hnav-cov hlau tsis muaj zog rau kev tsim kho tshuab tuaj yeem txhim kho kev ua haujlwm tau zoo, txuas ntxiv cov cuab yeej siv lub neej, thiab txo cov nqi tsim khoom.
