Chinangwa chemidziyo yakagadziridzwa: Wedzera ma modifiers uye madhizaini matsva kune yekurima base bhitumeni kuti uvandudze zvizere kuita kwebhiriji rebhitumini, kusanganisira tembiricha inonzwa zvimiro, kugadzikana kwekushisa kwepamusoro, kuderera kwetembiricha kubatana, kuramba kuchembera uye mabasa akakosha ekudzivirira.

Nheyo yezvinhu zvakagadziridzwa: Asphalt i polymer material compound inoumbwa neasphaltenes, collagen fibers, paraxylene uye saturated hydrocarbons. Asphaltenes inotsamira pa collagen fibers kuti ipararire muparaxylene uye saturated hydrocarbons kuburitsa colloidal mhinduro chimiro. Asphaltene Kana zvigadzirwa zvidiki, bhitumini ine yakanaka kunamatira, deformation yepurasitiki, uye fluidity, asi yakashata kugadzikana kwekushisa uye ductility. Iyo polymer modifier yakafanana neasphaltene mu asphalt. Kuwedzerwa kwayo, mushure mekunyunguduka kwakakwana uye kuzvimba neasphalt, Iyo xylene uye collagen fibers muasphalt inotorwa kuti igadzire itsva colloidal solution. Munguva yekusanganiswa kwemusanganiswa, musanganiswa unodziya uye asphalt zvinopfapfaidzwa muhari yekusanganisa panguva imwe chete. Pasi pe mechanical mixing, yakawanda ye surfactant micelles inosangana neasphalt inopisa, uye mvura yekunze ye micelles inokurumidza kubuda uye inorasikirwa, zvichiita kuti boka re lipophilic ribatane neasphalt; nepo mvura yakasara isati yarasika inosangana neboka re hydrophilic re surfactant. Yakasanganiswa, yakawanda yemaitiro shrinkage mvura ine lubricating effect inogadzirwa pakati peasphalts inovhara asphalt musanganiswa; kuburikidza nemafuta ekuzora emvura yekugadzira shrinkage, haisi kungovandudza kusanganisa kwemusanganiswa, asiwo inodzivirira dambudziko kune imwe nhanho. Asphalt dhaka iri kudonha.
Izvi hazvisi kungochengetedza kana kuvandudza kusungirirwa, deformation yepurasitiki uye fluidity yeasphalt yepakutanga, asiwo inovandudza kugadzikana kwekushisa uye ductility yeasphalt, nokudaro kuzadzisa chinangwa chekuvandudza kushanda kweasphalt mabhiriji;
Yakagadziridzwa tekinoroji yekugadzirisa tekinoroji: iyo modhifita uye modhifita yakaenzana uye yakanyatso kuparadzirwa mugavhu rekurima asphalt, uye wozocheka nepamusoro-inomhanya diki poda michina kuti uwedzere nzvimbo yekubatana pakati peiyo asphalt yekutanga uye ma modifiers kuti ive nechokwadi chakakwana Kuzvimba, kukura uye kusimudzira. . Izvo hazvingowedzere mwero wekushandiswa kweiyo modifier asi zvakare inovandudza mashandiro eiyo asphalt yekutanga.
