Yi amfani da SBS azaman babban kayan don tantance masu dacewa da tsarin su. Yi amfani da mahaɗa na yau da kullun don ƙara wani yanki na masterbatch zuwa reactor, zafi da haɗa shi da bitumen matrix daban-daban a kusan 160 ° C, kuma sanya masterbatch ta hanyar granulation.
Tunda bitumen da aka gyara na polymer yana buƙatar amfani da kayan aiki na musamman kamar manyan injinan colloid don sarrafawa, kuma ana amfani da polymers ne kawai don haɗa bitumen da aka gyara, galibi gauraya ce ta jiki mai sauƙi, kuma babu haɗin sinadari tsakanin injin polymer da matrix. bitumen. Kwanciyar kwanciyar hankali na tsarin gauraye ba shi da kyau, kuma fasaha mai haɗawa na SBS da matching compatibilizer don yin SBS modified bitumen masterbatch inganta danko kwarara hali na guda SBS modifier da kuma rage zafin jiki na danko kwarara yankin na masterbatch. , da blending zafin jiki ne rage daga 180 ~ 190 ℃ zuwa 160 ℃, da kuma yin amfani da na al'ada hadawa kayan aiki iya saduwa da uniform watsawa da hadawa na polymer da bitumen, game da shi rage samar rigor da ceton samar da halin kaka.
