(1) Siv dav hauv kev txhim kho asphalt pavement, cement pob zeb pavement thiab roadbed. Nws tuaj yeem siv rau ob qho tib si nyuaj thiab hloov tau yooj yim pavements. Piv nrog rau cov pavements ib txwm, nws tuaj yeem txo tus nqi, ua kom lub neej ntev kev pab cuam thiab tiv thaiv kev cuam tshuam ntawm txoj kev tawg.
(2) Lub thickness ntawm cov khoom yog tsim nyog, nws yog ib qho yooj yim mus ua ke nrog asphalt pavement, thiab nws tsim ib tug cais txheej tom qab sib txuas nrog cov roj nplaum, uas muaj lub luag hauj lwm ntawm waterproofing thiab kub preservation.
(3) Lub teeb nyhav thiab lub zog siab. Lub zog tensile yog ≥8 KN / m, thiab elongation yog 40 ~ 60%, uas ua tau raws li cov kev cai ntawm geotextiles hauv JTJ / T019-98 "Technical Specification for Highway Geosynthetics".
(4) Qhov saum npoo yog ntxhib thiab tsis yooj yim rau swb. Thaum tso, tig lub npoo nrog rau sab ntxhib tom qab kev kho tshwj xeeb, ua kom cov coefficient ntawm kev sib txhuam, ua kom lub zog sib txuas ntawm cov txheej txheej saum npoo, tiv thaiv kom tsis txhob raug dov thiab puas los ntawm lub log thaum tsim kho, thiab tib lub sijhawm tiv thaiv tsheb thiab paver los ntawm slipping ntawm daim ntaub. .
(5) Nws muaj kev tiv thaiv ultraviolet, txias thiab khov tsis kam, tshuaj tiv thaiv corrosion thiab kev puas tsuaj lom lom.
(6) Kev tsim kho yooj yim thiab siv tau zoo. Nws tsis yog ib qho yooj yim los khaws cov log tsheb ntawm lub tsheb kom ntseeg tau tias muaj txiaj ntsig zoo ntawm kev tsim kho.
