1. Txhim kho qhov kub thiab ruaj khov ruaj khov thiab ruaj khov. Vim yog qhov peb-seem kev faib tawm ntawm polyester fiber ntau monofilaments, nws tseem muaj cov adsorption muaj zog rau asphalt thiab tsis kis. Nws tuaj yeem adsorb ntau dhau li ntawm asphalt thiab ua rau lub viscosity ntawm asphalt Ua kom ntau dua qub thiab cohesion, tib lub sijhawm, vim yog lub pob zeb ntoo khaub lig-tawv tawv thiab cov dej khov, txo kev khiav dej num ntawm asphalt, txwv qhov kev hloov chaw tom qab lossis ntws ntawm kev sib sau, tau zoo tuaj yeem txhim kho qhov kub thiab txias tsis txaus, thiab ruaj khov kom muaj cov fiber ntau asphalt pob zeb ua tiav Cov degree tau zoo dua.
2. Txhim kho qhov qis-kub tawg tsis kam, fiber ntau' s adsorption ntawm asphalt, ua rau muaj qhov nce siab ntawm cov asphalt cov ntsiab lus hauv asphalt pob zeb, thiab cov ntsiab lus siab dua asphalt, kom cov tshuaj fiber ntau sib xyaw ua ke tseem tswj kev yoog thiab siab kub ntawm -40 ℃ qis kub Lub zog tensile ntawm cov khoom ua tau zoo tiv thaiv shrinkage kev nyuaj siab, txhim kho qhov tsis tshua muaj kub tawg tsis kam ntawm qhov sib xyaw, txo cov cim ntawm kub shrinkage tawg thiab tiv thaiv kev txhim kho ntawm tawg tawg.
3. Txhim kho cov kev ua kom tsis muaj zog tiv thaiv kev ua haujlwm Asphalt pavement yog raug rau qhov rov ua dua ntawm cov log thauj khoom hauv qab qhov kev ua ntawm ib puag ncig kub sab nraud. Thaum cov load tau rov ua ntau dua rau qee qhov ntau ntawm lub sijhawm, qhov kev ntxhov siab tsim tawm rau hauv txoj kev pua hauv qab lub nra yuav dhau tus txheej txheem tiv thaiv ntawm qhov ua kom tsis muaj zog. Kev nrib pleb hauv txoj kev ua rau ua rau lub cev puas tsuaj thiab puas. Tom qab qhov sib ntxiv ntawm cov xov hluavtaws polyester, cov teeb tsa kev faib ua ke ntawm cov fiber ntau monofilaments hauv kev sib xyaw ua kom lub zog khov kho thiab txhim kho qhov qaug zog tsis kam ntawm asphalt pob zeb.
4. Txhim kho cov dej tsis sib haum Cov dej ruaj ntseg ntawm lub pob zeb asphalt txhais tau hais tias lub pob zeb asphalt tau raug rau cov kev hloov dua tshiab ntawm cov teeb meem thauj khoom thiab qhov kub nce siab thiab cuam tshuam hauv cov dej. Qhov sib ntxiv ntawm cov polyester fiber tuab ua ke rau asphalt zaj duab xis, txo lub zog ntawm dej hloov asphalt, thiab txo cov dej nkag rau hauv asphalt pob zeb. Tsis tas li ntawd, cov fiber' s adsorption effect ua rau kom muaj qhov viscosity ntawm asphalt thiab txhim kho cov asphalt Lub zog khi ntawm qhov kev sib xyaw ua kom zoo dua qhov muaj peev xwm ntawm cov yeeb yaj kiab interface tsim los ntawm asphalt thiab cov khoom sib xyaw hauv asphalt sib xyaw kom tiv thaiv dej tawm, yog li txhim kho cov dej ruaj ntseg ntawm cov asphalt sib tov.
