1. Txhim kho qhov kub thiab txias ruaj khov thiab ua kom muaj qhov kub thiab txias. Vim yog peb-dimensional tis ntawm polyester (polyester) staple fiber monofilament, nws muaj zog adsorption nrog asphalt thiab tsis entangle. Nws tuaj yeem nqus tau cov asphalt ntau dhau thiab ua rau asphalt Lub viscosity thiab cohesion ntawm asphalt ua loj dua, thiab tib lub sijhawm, vim qhov kev sib txuas ntawm crisscross thiab bridging nyhuv, qhov kev khiav hauj lwm ntawm asphalt yog txo, lub lateral txav los yog ntws. cov aggregate yog txwv, thiab qhov kub siab stability yog zoo txhim khu kev qha, thiaj li hais tias cov fiber ntau stability ntawm asphalt qhob tau zoo heev.
2. Txhim kho qhov kub thiab txias tsis kam ntawm asphalt sib tov, adsorption ntawm fiber ntau rau asphalt, nce cov ntsiab lus asphalt hauv cov asphalt sib tov, thiab nce cov ntsiab lus asphalt, kom cov fiber ntau asphalt sib tov muaj peev xwm tswj tau yooj yim thiab ua haujlwm siab ntawm {{ 2}} degree Tensile zog, zoo tiv thaiv shrinkage kev nyuaj siab, txhim kho qhov kub-kub tawg tsis kam ntawm qhov sib tov, txo thermal shrinkage tawg, thiab tiv thaiv kev tawg tawg.
3. Txhim kho kev tiv thaiv kev qaug zog kev ua haujlwm Asphalt pavement yog raug rov qab log loads nyob rau hauv qhov kev txiav txim ntawm sab nraud kub ib puag ncig. Thaum lub load rov qab rau ntau tshaj li ib lub sij hawm, qhov kev ntxhov siab tsim nyob rau hauv lub pavement nyob rau hauv lub load yuav ntau tshaj li cov qauv tsis kam ntawm lub zog txo. Cov kab nrib pleb tshwm rau ntawm txoj kev, ua rau qaug zog puas tsuaj. Tom qab ntxiv polyester fibers, qhov sib faib ntawm fiber ntau monofilaments nyob rau hauv cov sib tov ua rau kom cov tawv nqaij modulus thiab txhim kho qhov qaug zog tsis kam ntawm asphalt pob zeb.
