Cov xuab zeb zoo thiab cov ntxhia sib xyaw ua ke yog ob qho tib si uas siv rau hauv cov dej tsis muaj dej, txhua qhov ua haujlwm sib txawv hauv kev siv sib txawv.
Ua ntej, cov xuab zeb zoo yog cov muab tub lim zoo nrog cov khoom ntim zoo thiab dej permeability. Nws feem ntau yog siv rau hauv daim ntawv thov uas xav tau cov dej permeability siab, xws li hauv cov vov tsev, qhov twg nws tuaj yeem txhim kho qhov permeability ntawm lub ru tsev. Tsis tas li ntawd, cov xuab zeb zoo muaj cov khoom zoo heev compaction, zoo sau cov khoob me me thiab txhim kho tag nrho cov kev ua tau zoo ntawm cov txheej txheem dej.
Mineral aggregate, ntawm qhov tod tes, yog cov muab tub lim loj dua nrog cov compressive zoo heev thiab puas ua haujlwm. Nws feem ntau yog siv rau hauv daim ntawv thov uas yuav tsum tau muaj zog thiab hnav tsis kam, xws li hauv qab daus waterproofing daim nyias nyias, qhov uas nws muaj peev xwm ntxiv dag zog rau cov waterproofing txheej thiab txhim khu lub zuag qhia tag nrho lub zog thiab stability ntawm cov qauv.
Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm cov xuab zeb zoo thiab cov ntxhia sib sau ua ke hauv cov ntaub ntawv siv dej tsis zoo yog nyob hauv lawv cov dej permeability, lub zog, thiab hnav tsis kam. Xaiv qhov tsim nyog muab tub lim raws li cov ntawv thov tshwj xeeb tuaj yeem txhim kho kev ua haujlwm ntawm cov txheej txheem dej tsis zoo, txuas ntxiv nws lub neej kev pabcuam, thiab ua kom muaj kev nyab xeeb thiab ruaj khov ntawm lub tsev qauv. Kuv vam tias txhua tus neeg yuav xaiv cov khoom tsim nyog thaum siv cov khoom siv dej tsis zoo los muab kev tiv thaiv zoo dua rau lub tsev qhov dej tsis zoo.
