ʻO ka asphalt i hoʻololi ʻia e hoʻohui i nā admixtures waho (modifiers) e like me ka rubber, resin, high molecular polymers, finely ground rubber powder a i ʻole nā ​​mea hoʻopihapiha ʻē aʻe, a i ʻole e hana i nā hana e like me ka hoʻomaʻamaʻa ʻana o ka asphalt e hana i ka asphalt a i ʻole ka hui ʻana o ka asphalt. Hiki ke hoʻomaikaʻi ʻia ka binder asphalt.
ʻElua mau hana no ka hoʻololi ʻana i ka asphalt. ʻO kekahi e hoʻololi i ka haku mele ʻana o ka asphalt, a ʻo ka mea ʻē aʻe e hoʻokaʻawale like i ka mea hoʻololi i ka asphalt e hana i kahi ʻano pūnaewele spatial.
ʻO ka ʻōpala a me ka thermoplastic elastomer i hoʻololi ʻia i ka asphalt
E komo pū ana: asphalt hoʻololi ʻia i ka lāʻau maoli, SBS i hoʻololi ʻia ka asphalt (ka mea i hoʻohana nui ʻia), styrene-butadiene rubber modified asphalt, chloroprene rubber modified asphalt, butyl rubber modified asphalt, butyl rubber modified asphalt, waste rubber and regeneration Rubber asphalt hoʻololi ʻia. asphalt (e like me ka ethylene propylene rubber, nitrile rubber, etc.).Plastic and synthetic resin modified asphalt
Me: polyethylene hoʻololi asphalt, ethylene-vinyl acetate polymer asphalt hoʻololi ʻia, polystyrene modified asphalt, coumarin resin modified asphalt, epoxy resin modified asphalt, α-olefin random polymer modification asphalt.
ʻO ka asphalt i hoʻololi ʻia i ka polymer
Hoʻohui ʻia ʻelua a ʻoi aku paha polymers i ka asphalt i ka manawa like e hoʻololi i ka asphalt. ʻO nā polymers ʻelua a ʻoi aʻe paha i ʻōlelo ʻia ma ʻaneʻi he ʻelua polymers kaʻawale, a i ʻole hiki ke lilo i mea i kapa ʻia he polymer alloy i hui mua ʻia e hana i ka polymer interpenetrating network.
