(1) Tswj nruj rau kev nkag thiab tawm ntawm cov tsheb nqa cov khoom sib xyaw, thiab txwv tsis pub lub tsheb tig los sib tsoo, sib tsoo, thiab muab cov khoom sib tsoo ntawm cov ntawv pov tseg kom tiv thaiv kev puas tsuaj rau iav fiber ntau.
(2) Lub iav fiber ntau daim phiaj nplaum yog yooj yim soluble hauv dej. Tsis txhob thov thaum nws los nag lossis ntub.
(3) Lub iav fiber ntau ua los ntawm cov iav fiber ntau, uas nws nquag ua rau tib neeg tawv nqaij. Cov neeg ua haujlwm tsim kho yuav tsum hnav cov hnab looj tes tiv thaiv.
(4) Thaum cov roj hmab quav siv los txhaj dej kom nws qhov hnyav, tus nqi ntawm cov dej txhaj yuav tsum tsis txhob dhau lawm kom tiv thaiv nws dhau ntawm cov iav fiber ntau daim phiaj thiab ua rau nws sab nraub qaum thiab lub plab poob viscosity.
(5) Lub sijhawm tso ntawm cov iav fiber ntau daim phiaj, yog tias pom tias muaj cov potholes me me ntawm cov thawj ntawm cov txheej txheem uas tsis tau sau ua ntej, koj tuaj yeem txiav tawm cov potholes sib haum ntawm cov phiaj hluav taws xob kom sib xyaw asphalt ntawm Txoj kev npaj thaum lub ntim tas lawm, lub qhov tuaj yeem ua kom tiav.
(6) Thaum cov phiajcim tau tso, txoj kev kub yuav tsum nyob nruab nrab ntawm 5 ° C thiab 60 ° C.
