I roto i te uku whakaemulsified, he awe ano te uara pH ki runga i te reiti demulsification. I mua i te ako i te awe o te pH i runga i te tere o te whakaheke o te asphalt kua whakaemihia, ka whakamaramahia nga tikanga whakamohoatanga o te anionic emulsified asphalt me ​​te cationic emulsified asphalt.

Cationic whakaemulsified asphalt demulsification whakawhirinaki i runga i te utu pai o te ngota hauota i roto i te rōpū amine i roto i te hanganga matū o te emulsifier uku ki te affinity ki te utu kino o te aggregate. No reira, ka pehia te wai i roto i te uku whakaehunga, ka rewa. Kua oti te whakamaaramatanga o te uku whakaemulsi. No te mea ko te whakaurunga o te waikawa pH-whakatikatika ka piki ake te utu pai, ka whakaroa te whakakotahitanga o te utu pai e mauria ana e te whakaemulsifier me te whakahiato. No reira, ko te pH o te cationic emulsified asphalt ka pa ki te reiti demulsification.
Ko te utu kino o te whakaemulsifier anionic i roto i te uku whakaemulsified anionic he mea wehe tahi me te utu kino o te whakahiato. Ko te whakamaaramatanga o te anionic emulsified asphalt e whakawhirinaki ana ki te piri o te uku ki te whakahiato kia kohia te wai. Ko te nuinga o nga wa e whakawhirinaki ana nga ngota hauwai ki nga ngota o te hāora ki te hydrophilic, a ko nga ngota hāora e hanga here hauwai ki te wai, ka puhoi te whakaetonga o te wai. Ka whakanuia te painga o te hononga hauwai i raro i nga tikanga waikawa me te ngoikore i raro i nga tikanga kawakore. No reira, ka teitei ake te pH, ka puhoi te tere o te whakaheke i roto i te haupapa whakaemulsi anionic.
