I-asphalt elungisiweyo kukongeza imixube yangaphandle (i-modifiers) njengerabha, i-resin, iipolymers zemolekyuli ephezulu, umgubo werabha ocolekileyo ocoliweyo okanye ezinye izihluzi, okanye uthathe amanyathelo afana nokucutshungulwa kwe-oxidation ethambileyo ye-asphalt ukwenza i-asphalt okanye i-asphalt umxube. i-asphalt binder inokuphuculwa.
Zimbini iindlela zokuguqula i-asphalt. Enye kukutshintsha ukwakheka kweekhemikhali ze-asphalt, kwaye enye kukwenza isilungisi sisasazwe ngokulinganayo kwi-asphalt ukwenza ulwakhiwo oluthile lwenethiwekhi yendawo.
Irabha kunye ne-thermoplastic elastomer eguqulwe i-asphalt
Kubandakanya: i-asphalt yerubha yendalo, i-asphalt eguqulweyo ye-SBS (eyona isetyenziswa kakhulu), i-asphalt ye-styrene-butadiene yerabha, i-asphalt yerubha eguqulweyo ye-chloroprene, i-asphalt ye-butyl yerabha, i-asphalt ye-butyl yerabha, i-asphalt eguquguqukayo yerabha, i-rubber yenkunkuma kunye nokuhlaziywa ngokutsha kwe-asphalt yerabha eguqulweyo, enye irabha elungisiweyo. i-asphalt (efana ne-ethylene propylene rubber, i-nitrile rubber, njl.) .Iplastiki kunye ne-synthetic resin modified asphalt
Kubandakanya: i-polyethylene eguqulwe i-asphalt, i-ethylene-vinyl acetate polymer i-asphalt eguquliweyo, i-polystyrene eguqulelwe i-asphalt, i-coumarin resin eguqulelwe i-asphalt, i-epoxy resin eguqulelwe i-asphalt, i-alpha-olefin i-asphalt yokuguqulwa kwe-polymer random.
I-asphalt ehlaziyiweyo yepolymer edibeneyo
Iipolymers ezimbini okanye ngaphezulu zongezwa kwi-asphalt ngexesha elifanayo ukuguqula i-asphalt. Iipolymers ezimbini okanye ngaphezulu ezikhankanywe apha zinokuba yi-polymers ezimbini ezihlukeneyo, okanye zinokuthi zibizwa ngokuba yi-polymer alloy ehlanganiswe kwangaphambili ukwenza i-polymer interpenetrating network.
