Ko te bitumen e kiia nei ko te whakarewa i te bitumen. Na roto i te mahi o te emulsifier metipu whakaehunga bitumen, ka marara te bitumen i roto i te wairewa wai kei roto i te nui o te emulsifier i roto i te ahua o nga topata pai ki te hanga i te hinu-in-wai emulsion asphalt. Te wai maroke i te pāmahana rūma. Ko te bitumen whakaemulsified e tohu ana ki te bitumen whakaemulsified hei mea turanga, bitumen whakarereke hei whakarereketanga o waho.
Ka hanumi nga rawa, ka whakakorikori, ka taka ki roto i te whakaehunga whakangao bitumen me etahi ahuatanga i raro i te rere o te tukanga. Ko tenei whakaehunga whakauru ka kiia ko te bitumen whakaemulsified.

Ka taea te wehea te tukanga whakaputa o te tipu whakaehunga bitumen ki nga waahanga e wha:
1. I muri i te hanga i te bitumen kua whakaemulsi, me tapirihia te whakarereketanga taherapa, ara, tuatahi whakaewhero ka whakarereke;
2. Whakaranuhia te whakahuri taherapa ki roto i te wairewa wai whakaehunga, katahi ka uru ki te mira colloid me te bitumen hei whakaputa i te bitumen whakaemulsified;
3. Whakanohia te whakakini taherapa, te wairewa wai whakaemulsifier, me te bitumen ki roto i te mira colloid i te wa ano hei hanga i te bitumen whakaemulsified (ko nga tikanga e rua o te 2 me te 3 ka kiia ko te whakaemulsified i te wa e whakarereketia ana);
4. Whakakotahitia te parapara kua whakarereketia hei whakaputa i te bitumen whakarereke.

whakatikatika rōrahi production otipu whakaehunga bitumen
1. I te wa o te mahi whakaputa, me ata titiro ki te panui o te inemahana i te putanga o te uku whakaehunga me te tuhi i te uara tika.
2. I te wa e hiahia ana koe ki te whakanui ake i te kaha o te whakaputa, me whakanui tuatahi koe i te tere motika o te papu wai hopi. I tenei wa, ka heke te panui o te inemahana, katahi ka ata whakatika te tere o te motini o te papu uku. I tenei wa, ka piki ake te panui o te ine wera. Ka tae te panui o te inemahana ki te panui kua tuhia, kati te whakatikatika; A, no te whakaiti i te kaha whakaputa, tuatahi whakaiti i te tere motopaika o te papu uku. I tenei wa, ka heke te panui o te inemahana, katahi ka ata whakaheke te tere o te motini o te papu wai hopi. I tenei wa, ka piki te panui o te inemahana. Ka tae te panui o te inemahana ki te panui kua tuhia, katia te whakatikatika.
