Mo nga kaiwhakamahi taputapu, ko te nui o nga rauemi e whakamahia ana ko te arotahi o ia kaiwhakamahi. Me whai mana nui ki tenei hononga i roto i te mahi whakaputa. Ko te kaihanga o te Rōpū Sinoroader e whai ake nei ka tātari i te nui o te whakaemi i whakamahia.

I te wa e whakaemihia ana e nga taputapu o te parapara, ka pai ake te whakahaere i te pāmahana o te parapara i runga ake i te 130°C kia pai ake te rere o te wai; 2. Ko te nui o te emulsifier te tikanga 8-14‰ o te uku whakaemulsified, ara, 8-14kg mo ia tone o te uku whakaemulsified (he nui ake i te 50%) te mea whakamahana, he 60-70°C te pāmahana. Me whakamahi te emulsifier i waenganui me te rohe o runga o te hanga, 10 kg mo ia tone o te asphalt whakaemulsified, he 20 kg ranei mo te tone wai (he 50%) te kiko o te uku; Ko te nui o te BE-3 emulsifier ko te tikanga 18-25‰ o te uku whakaemulsified, ara, 18-25kg ia ton o te uku whakaemulsified (he nui atu i te 50%) te ihirangi uku, me te pāmahana otinga emulsifier ko 60-70°C. Me whakamahi te emulsifier ki nga rohe o runga me raro o te inenga mo te hanga tuatahi kia tutuki pai ai te whakaputanga. 24 kg mo ia tone o te asphalt whakaemulsified, he 48 kg ranei mo te tone wai (50% te ihirangi asphalt), ka taea te whakaheke i runga i nga tikanga tuturu i muri i te hanga maeneene.
