Sepheo sa lisebelisoa tse fetotsoeng: Eketsa li-modifiers le lisebelisoa tse ncha ho sekontiri sa motheo sa temo ho ntlafatsa ka botlalo ts'ebetso ea borokho ba sekontiri, ho kenyelletsa le thepa ea ho lemoha mocheso, botsitso ba mocheso o phahameng, ho kopana ha mocheso o tlase, ho hanyetsa botsofali le mesebetsi ea bohlokoa ea tšireletso ea lihokelo.

Molao-motheo oa lisebelisoa tse fetotsoeng: Asphalt ke motsoako oa polymer o entsoeng ka asphaltenes, collagen fibers, paraxylene le saturated hydrocarbons. Li-asphaltene li itšetleha ka likhoele tsa collagen ho hasana ka har'a paraxylene le li-hydrocarbon tse ngata ho hlahisa sebopeho sa tharollo ea colloidal. Asphaltene Ha metsoako e le nyenyane, sekontiri se na le sekhomaretsi se setle, deformation ea polasetiki, le mokelikeli, empa mocheso o fokolang oa botsitso le ductility. Polymer modifier e tšoana le asphaltene ka asphalt. Ho eketsoa ha eona, ka mor'a ho qhibiliha ho lekaneng le ho ruruha ka asphalt, The xylene le collagen fibers ka asphalt li kenngoa ho etsa tharollo e ncha ea colloidal. Nakong ea motsoako oa motsoako, motsoako o mofuthu oa motsoako le asphalt o fafatsoa ka har'a pitsa ea motsoako ka nako e le 'ngoe. Tlas'a ho kopanya mechine, li-micelles tse ngata tsa surfactant li kopana le asphalt e chesang, 'me metsi a ka ntle a li-micelles a potlakela ho fetoha mouoane' me a lahleheloa, e leng se etsang hore sehlopha sa lipophilic se kopane le asphalt; ha metsi a setseng a sa kang a lahleha a kopana le sehlopha sa hydrophilic sa surfactant. E kopantsoe, metsi a mangata a shrinkage a nang le phello ea lubricating a hlahisoa pakeng tsa li-asphalt tse koahelang motsoako oa asphalt; ka phello ea lubricating ea shrinkage ea meralo ea metsi, ha e ntlafatse feela katleho ea motsoako oa motsoako, empa hape e qoba bothata ho isa tekanyong e itseng. Seretse sa asphalt sea putlama.
Sena ha se boloke feela kapa se ntlafatsa ho khomarela, deformation ea polasetiki le fluidity ea asphalt ea pele, empa hape e ntlafatsa botsitso ba mocheso le ductility ea asphalt, ka hona ho finyella morero oa ho ntlafatsa ts'ebetso ea marokho a asphalt;
Theknoloji ea ts'ebetso ea thepa e fetotsoeng: li-modifiers le li-modifiers li arotsoe ka mokhoa o ts'oanang le hantle ka har'a asphalt ea motheo ea temo, ebe li khaola ka mechini e potlakileng ea phofo e nyane ho eketsa sebaka sa ho ikopanya lipakeng tsa asphalt ea mantlha le li-modifiers ho netefatsa ho ruruha, kholo le nts'etsopele e lekaneng. . Ha e eketse sekhahla sa tšebeliso ea mofetoleli feela empa hape e ntlafatsa ts'ebetso ea asphalt ea mantlha.
