Kev ua haujlwm thiab kev saib xyuas cov lus qhia ntawm pavement sealing tshuab

Lub luag haujlwm tseem ceeb ntawm pavement sealing tshuab yog "sealing". Thaum cov kab nrib pleb tshwm rau ntawm txoj kev, yog tias cov kab nrib pleb tsis tau ua raws sijhawm, lwm yam xws li los nag yuav ua rau muaj kev puas tsuaj ntxiv rau txoj kev taug kev, ua rau cov kab nrib pleb nthuav dav thiab txawm tias cov pas dej yuav tshwm sim. Lub tshuab pavement sealing heats cov khoom sealing ntawm qhov kub thiab txias thiab txhaj nws tusyees rau hauv cov kab nrib pleb, yog li sau cov kab nrib pleb thiab sealing saum npoo. Cov khoom sib khi feem ntau yog asphalt lossis polymer cov ntaub ntawv, uas muaj zog adhesion thiab elasticity, tuaj yeem hloov mus rau thermal expansion thiab contraction hloov ntawm pavement nyob rau hauv ntau lub caij, thiab tsis yooj yim rau tawg dua. Qhov kev ua haujlwm no zoo tiv thaiv kev nthuav dav ntawm cov kab nrib pleb thiab tiv thaiv kev puas tsuaj ntxiv rau txoj kev qauv. Nws yog qhov yooj yim tshaj plaws thiab tseem ceeb ua haujlwm ntawm pavement sealing tshuab.
