Txoj kev niaj hnub no yuav tsum tiv taus cov xwm txheej hnyav heev - cov tsheb thauj khoom hnyav, qhov kub thiab txias hloov pauv, thiab ntev - lub sij hawm kev ntxhov siab. Txawm li cas los xij, hauv qab asphalt nto yog feem ntau saib tsis tau tab sis cov khoom tseem ceeb:fiberglass geogrid.
Qhov siab -cov khoom siv txhawb nqa kev ua tau zoo no ua rau "pob txha pob txha tsis pom," txhim kho txoj kev ua haujlwm ntev, txo qhov tawg, thiab txuas ntxiv lub neej kev pab cuam. Rau cov neeg cog lus, engineers, thiab cov neeg yuav khoom thoob ntiaj teb, nkag siab txog fiberglass geogrids yog qhov tseem ceeb rau kev txiav txim siab txog kev yuav khoom.
Fiberglass Geogrid yog dab tsi?
Fiberglass geogrid yog cov khoom siv geosynthetic tsim los ntawm siab -lub zog, alkali-dawb iav fibers woven rau hauv daim phiaj qauv thiab coated nrog hloov asphalt lossis polymer.
Cov qauv no muab:
Lub zog tensile siab (feem ntau 30-100 kN / m lossis siab dua)
Tsawg elongation (<3%)
Zoo heev thermal stability
Muaj zog tiv thaiv deformation
Tsis zoo li cov yas geogrids, fiberglass geogrids nthuav tawmsiab modulus, ua rau lawv tshwj xeeb tshaj yog nyob rau hauv asphalt reinforcement daim ntaub ntawv.
Fiberglass Geogrid ua haujlwm li cas?
Kev ua tau zoo ntawm fiberglass geogrid yog nyob rau hauv ob qho tseem ceeb engineering mechanisms:
Kev sib tshuam thiab kev txhawb zog
Thaum ntsia nruab nrab ntawm asphalt khaubncaws sab nraud povtseg, kub bitumen nkag mus rau hauv daim phiaj apertures thiab bonds nruj nreem tom qab txias. Qhov no tsim cov txheej txheem sib xyaw ua ke uas txwv kev sib sau ua ke thiab tiv thaiv rutting.
Crack Resistance thiab Stress Distribution
Fiberglass geogrids faib cov kev ntxhov siab tshwm sim los ntawm cov kab nrib pleb hauv qab, ua haujlwm qeeb lossis tiv thaiv kev cuam tshuam los ntawm kev ncav cuag qhov chaw pavement.
Qhov kev ua haujlwm dual no ua rau muaj txiaj ntsig zoo rau kev taug kev hauv ob qho tib si siab - kub deformation thiab qis - qhov kub thiab txias tawg.
Cov ntawv thov tseem ceeb
Fiberglass geogrids tau dav siv hauv:
Asphalt pavement reinforcement (kev loj, kev hauv nroog)
Tshav dav hlau khiav
Kev tsheb hnyav
Txoj kev rehabilitation thiab overlay tej yaam num
Cov ntaub ntawv teb qhia tau hais tias kev teeb tsa zoo fiberglass geogrids tuaj yeem:
Txo rutting txog li 50-60%
Ncua tawg tawm los ntawm ntau xyoo
Txuas lub neej pavement los ntawm 30% lossis ntau dua
Fiberglass vs Polyester Geogrid: Yuav Xaiv Ib Yam Dab Tsi?
| Feature | Fiberglass Geogrid | Polyester Geogrid |
|---|---|---|
| Modulus | Siab heev | Nruab nrab |
| Elongation | Tsawg | Siab dua |
| Kev siv zoo tshaj plaws | Asphalt reinforcement | Av stabilization |
| Kub Resistance | Zoo heev | Zoo |
Xaus:
Fiberglass geogrid yog qhov kev xaiv zoo tshaj plaws rau asphalt khaubncaws sab nraud povtseg, thaum polyester yog zoo dua rau subgrade reinforcement.
Yuav Ua Li Cas Xaiv Txoj Cai Fiberglass Geogrid
Rau cov kws tshaj lij kev yuav khoom, xaiv cov khoom tsim nyog suav nrog ntau yam tseem ceeb:
Tensile zog
30–50 kN/m → Txoj kev hauv nroog
80–{1}} kN/m → Highways, tshav dav hlau
Aperture Loj
Yuav tsum phim 0.5–1.0 × aggregate loj kom pom kev cuam tshuam.
Txheej hom
Hloov kho asphalt txheej kom muaj kev sib raug zoo nrog cov txheej txheem bitumen.
