Asphalt wosinthidwa ndikuwonjezera zosakaniza zakunja (zosintha) monga mphira, utomoni, ma polima apamwamba kwambiri, ufa wa rabara wosakanizidwa bwino kapena zodzaza zina, kapena kuchitapo kanthu monga kusakaniza kwa oxidation wa phula kuti apange phula kapena phula kusakaniza asphalt binder ikhoza kusinthidwa.
Pali njira ziwiri zosinthira phula. Imodzi ndikusintha kapangidwe kake ka phula, ndipo ina ndikupangitsa kuti chosinthiracho chigawidwe mofanana mu asphalt kuti apange mawonekedwe enaake ochezera.
Rubber ndi thermoplastic elastomer yosinthidwa phula
Kuphatikizirapo: phula lachilengedwe losinthidwa mphira, phula losinthidwa la SBS (lomwe limagwiritsidwa ntchito kwambiri), mphira wosinthidwa wa styrene-butadiene, phula la chloroprene losinthidwa, phula losinthidwa la butyl, phula losinthidwa la butyl, mphira wotayika, mphira wowonongeka ndi phula losinthika la Rubber, mphira wina wosinthidwa. phula (monga mphira wa ethylene propylene, labala wa nitrile, etc.) .Pulasitiki ndi phula lopangidwa ndi phula losinthidwa
Kuphatikizapo: polyethylene modified asphalt, ethylene-vinyl acetate polymer modified asphalt, polystyrene modified asphalt, coumarin resin modified asphalt, epoxy resin modified asphalt, α-olefin random polima modified asphalt.
Blended polymer kusinthidwa asphalt
Ma polima awiri kapena kupitilira apo amawonjezedwa ku asphalt nthawi imodzi kuti asinthe phula. Ma polima awiri kapena angapo omwe atchulidwa pano akhoza kukhala ma polima awiri osiyana, kapena akhoza kukhala otchedwa alloy polima omwe asakanizidwa pasadakhale kuti apange maukonde a polima interpenetrating.
