Lub neej ntev ntawm cov nyom pavers yog cuam tshuam los ntawm ntau yam, nrog rau cov khoom siv, kev tsim khoom, ib puag ncig, thiab kev siv thiab tu. Hais txog cov ntaub ntawv, nkauj xwb HDPE nyom pavers, vim lawv zoo heev tiv thaiv UV rays, kub variations, thiab tshuaj corrosion, yuav kav 50-100 xyoo. Hloov kho PP lossis txhawb nqa cov yas nyom pavers kuj muaj lub neej ntev tshaj 30 xyoo, tshwj xeeb tshaj yog thaum lawv cov qauv txhawb zog thiab lawv lub zog compressive ncav cuag lossis tshaj 200 tons. Hloov pauv, cov nyom pavers ua los ntawm cov khoom siv rov ua dua tshiab muaj lub neej luv dua, feem ntau ntawm 5-10 xyoo, thiab muaj kev cuam tshuam rau cov teeb meem xws li hmoov av, thermal expansion thiab contraction deformation, thiab txo cov kabmob muaj peev xwm.
Ib puag ncig yam tseem ceeb tseem cuam tshuam rau lub neej ntawm cov nyom pavers. Hauv cov cheeb tsam los nag, cov dej tsis zoo ua rau cov txheej txheem kev laus ntawm cov nyom pavers; Yog li ntawd, ib qho kev nqes hav yog tsim nyog los pab kom cov dej ntws tawm. Hauv cov cheeb tsam uas muaj hluav taws xob UV muaj zog, cov nyom pavers uas tsis muaj UV- cov txheej tiv thaiv yuav muaj 30% -50% luv dua lub neej. Tsis tas li ntawd, lub peev xwm load-bearing kuj yog ib qho tseem ceeb cuam tshuam rau lub neej. Nyom pavers rau qhov chaw nres tsheb zoo tib yam (load Tsawg dua lossis sib npaug li 20 tons / m²) tuaj yeem ncav cuag lawv lub neej nominal, thaum txoj kab hluav taws xob (load Ntau dua lossis sib npaug li 40 tons / m²) yuav tsum muaj cov pavers tuab (Ntau dua lossis sib npaug li 50mm), txwv tsis pub lawv lub neej yuav luv luv.
Kev txhim kho thiab kev saib xyuas kuj tseem cuam tshuam rau lub neej ntawm cov nyom pavers. Thaum lub hauv paus kev kho mob, siv 15cm gravel txheej nrog geotextile tuaj yeem tiv thaiv kev sib haum xeeb thiab ua kom muaj sia nyob li 20%. Rau kev saib xyuas tsis tu ncua, cov dej ntws yuav tsum tau muab ntxuav txhua hli kom tsis txhob muaj dej thiab xeb, thiab cov av ploj yuav tsum tau rov ua dua txhua xyoo txhawm rau tiv thaiv kev laus vim raug. Lub caij no, kev tswj cov nroj tsuag kuj tseem ceeb heev; nyom qhov siab yuav tsum tau tswj kom tsawg dua los yog sib npaug li 10cm kom tsis txhob muaj cov hauv paus puas rau cov qauv paver.
Hauv kev siv tswv yim, kuj tseem muaj qee qhov kev ua neej luv luv. Piv txwv li, ib qhov project siv PP nyom pavers tau ntsib loj - nplai hmoov tom qab 5 xyoos; hluav taws txoj kab uas tsis muaj thickened pavers ntsib rib breakage nyob rau hauv 10 xyoo; thiab qhov tsis muaj qhov muag tsis pom dej ua rau cov av thaiv thiab paver hloov chaw thiab deformation. Yog li ntawd, thaum xaiv thiab siv cov nyom pavers, yam xws li cov khoom siv, ib puag ncig, kev thauj khoom, thiab kev teeb tsa thiab kev saib xyuas yuav tsum raug txiav txim siab.
