Yakagadziridzwa asphalt ndeyekuwedzera ekunze admixtures (modhifita) senge rabha, resin, yakakwira molecular polymers, yakatsetseka yakagadzika rubber poda kana mamwe mafirita, kana kutora matanho akadai seakapfava oxidation processing yeasphalt kugadzira asphalt kana asphalt musanganiswa. asphalt binder inogona kuvandudzwa.
Pane nzira mbiri dzekugadzirisa asphalt. Imwe ndeyekushandura kemikari yeasphalt, uye imwe ndeyekuita kuti modifier igovane zvakaenzana muasphalt kuti igadzire imwe nzvimbo yetiweki network.
Rubber uye thermoplastic elastomer yakagadziridzwa asphalt
Kusanganisira: natural rabha yakagadziridzwa asphalt, SBS yakagadziridzwa asphalt (inonyanya kushandiswa), styrene-butadiene rubber yakagadziridzwa asphalt, chloroprene rubber yakagadziridzwa asphalt, butyl rubber yakagadziridzwa asphalt, butyl rabha yakagadziridzwa asphalt, tsvina yerabha uye regeneration Rubber yakagadziridzwa asphalt, imwe rabha yakagadziridzwa. asphalt (senge ethylene propylene rubber, nitrile rubber, etc.) .Plastic uye synthetic resin yakagadziridzwa asphalt
Kusanganisira: polyethylene modified asphalt, ethylene-vinyl acetate polymer modified asphalt, polystyrene modified asphalt, coumarin resin yakagadziridzwa asphalt, epoxy resin yakagadziridzwa asphalt, α-olefin random polymer modification asphalt.
Yakasanganiswa polymer yakagadziridzwa asphalt
Mapolymer maviri kana anopfuura anowedzerwa kune asphalt panguva imwe chete kugadzirisa asphalt. Iwo maviri kana anopfuura mapolymer ataurwa pano anogona kuve maviri akapatsanurwa mapolymer, kana anogona kuve anonzi anonzi polymer alloy akasanganiswa pamberi kuti agadzire polymer inopindirana network.
