Cov fiberglass geogrid tuaj yeem tiv tau zoo dua nrog cov pob zeb ua ke asphalt kom tsim lub cev sib xyaw tag nrho. Tshuab kho deg yog ntxiv rau tus thawj fiberglass geogrid, namely: nws tus kheej-siab ceev rhiab nplaum los yog hloov asphalt saum npoo txheej. Yog li, kev siv tus nqi ntawm cov staples loj loj nyob rau hauv kev siv hluav taws xob iav fiber ntau geogrids yog zam. Thiab lub caij nyoog ntev lub roadbed laus lub sijhawm. Txo cov kab nrib pleb, chaw nyob thiab lwm yam kab mob tshwm sim los ntawm kev sib cais ntawm fiberglass geogrid thiab lub hauv paus.
Raws li txheej txheej saum npoo, nws tuaj yeem muab faib ua: tus kheej-nplaum siab-rhiab nplaum thiab hloov kho asphalt nto-txheej iav fiber ntau geogrid thiab zoo tib yam iav fiber ntau geogrid yam tsis muaj kev kho tshwj xeeb. Hauv kev lag luam puas hloov iav fiber ntau geogrid kev lag luam thiab kev lag luam ntxiv, peb lub hom phiaj yeej ib txwm muaj pob zeb, tab sis yooj ywm thiab qhib, thiab yoog rau kev hloov pauv tas li, ib txwm ua lub hauv paus rau lub zog rau Qichang vam.
