I-asphalt eguquliwe iwukwengeza izixube zangaphandle (ama-modifiers) njengerabha, i-resin, ama-polymers amangqamuzana aphezulu, impushana yerabha egayiwe kahle noma amanye ama-filler, noma uthathe izinyathelo ezinjengokucubungula i-oxidation ethambile yetiyela ukwenza ingxube yetiyela noma itiyela Ukusebenza kwe-asphalt i-asphalt binder ingathuthukiswa.
Zimbili izindlela zokulungisa itiyela. Enye iwukushintsha ukwakheka kwamakhemikhali etiyela, kanti enye iwukwenza isilungisi sisabalaliswe ngokulinganayo ku-asphalt ukuze sakhe uhlaka oluthile lwenethiwekhi yendawo.
Irabha ne-thermoplastic elastomer eguquliwe itiyela
Kuhlanganisa: itiyela yemvelo eguquliwe yenjoloba, i-asphalt eguquliwe ye-SBS (esetshenziswa kakhulu kunazo zonke), i-asphalt ye-styrene-butadiene yerabha eshintshiwe, itiyela eguquliwe yenjoloba ye-chloroprene, i-asiphalt eshintshiwe yenjoloba ye-butyl, i-asphalt eguquliwe yerabha ye-butyl, irabha engcolile kanye nokuvuselelwa kabusha kwe-asphalt yerabha eguquliwe, enye injoloba eshintshiwe. itiyela (njengerabha ye-ethylene propylene, irabha ye-nitrile, njll.) .Plastic kanye ne-synthetic resin modified asphalt
Kuhlanganisa: i-polyethylene modified asphalt, i-ethylene-vinyl acetate polymer modified asphalt, i-polystyrene modified asphalt, i-coumarin resin modified asphalt, i-epoxy resin modified asphalt, i-α-olefin i-polymer modified asphalt engahleliwe.
I-asphalt eguquliwe ye-polymer ehlanganisiwe
Ama-polymers amabili noma ngaphezulu afakwa ku-asphalt ngesikhathi esifanayo ukuze kulungiswe i-asphalt. Ama-polymers amabili noma ngaphezulu okukhulunywe ngawo lapha angaba ama-polymer amabili ahlukene, noma angaba okuthiwa i-polymer alloy ehlanganiswe kusengaphambili ukuze akhe inethiwekhi ye-polymer interpenetrating.
