Ko te bitumen whakaehunga mo te papa moroiti te mea here mo te hanga moroiti. Ko tona ahuatanga ko te whakatutuki i te wa whakaranu ki te kohatu me te wa whakatuwhera mo nga waka i muri i te otinga o te whariki. Ki te whakamaarama, ka tutuki nga take e rua. Me nui te wa ranu, me tere te whakatuwheratanga o nga waka, heoi ano.
Me korero ano mo te bitumen whakaehunga. Ko te whakaehunga bitumen he hinu-in-wai whakaehunga bitumen. He wai kakato riterite i te pāmahana rūma. Ka taea te tono ma te makariri me te kore e hiahiatia kia whakamahana. He whakaora hiko, he pai ki te taiao. Kua wehea te bitumen whakaehunga ki nga momo momo e toru e ai ki nga momo whakaemulsifiers bitumen e whakamahia ana i roto i te whakaputanga: te pakaru puhoi, te pakaru reo, me te pakaru tere. Ko te bitumen whakaehunga e whakamahia ana i roto i te hanga moroiti-mata he puhoi te pakaru me te tere te whakatakoto i te bitumen whakaehunga cationic. Ka whakaritea tenei momo bitumen whakaehunga ma te whakamahi i te kapiti puhoi me te whakaturanga tere i te whakaemulsifier bitumen me te taapiri i nga whakarereke polymer. Ka taea e ia te whakatutuki i te wa ranu me te awenga tautuhinga tere. He pai te piri ki waenga i nga cation me te kohatu, na reira ka tohua te momo cationic.

Ko te kapiti puhoi me te whakatakoto tere o te bitumen whakaehunga e whakamahia ana mo te tiaki huarahi aukati. Arā, ka whakamahia i te wa e mau tonu ana te paparanga turanga engari kua pakaru te paparanga mata, penei i te maeneene o te mata o te rori, i ngatata, i ngatata, me era atu.
Tikanga hanga: Rehutia te paparanga hinu whakapiri i te tuatahi, katahi ka whakamahi i te papa hiri moroiti/slurry hei whariki. I te mea he iti te waahi, ka taea te whakamahi i te ranu a-ringa me te whariki i te bitumen whakaehunga me te kohatu. I muri i te whariki ka hiahiatia. Ka taea te whakamahi i muri i te tatari kia maroke te mata. E tika ana ki: hanga papa angiangi i roto i te 1 cm. Mena ka nui ake te 1 cm te matotoru, me whariki ki nga paparanga. Ka maroke tetahi paparanga, ka taea te whariki i te paparanga o muri mai. Mena he raruraru i te wa o te hanganga, ka taea e koe te whakapiri atu ki te ratonga kaihoko mo te korerorero!
Ko te bitumen whakaehunga kapiti puhoi me te whakarite tere he mea sima mo te hiri slurry me te whariki moroiti-mata. Ko te tino korero, i roto i te hanga hiri slurry whakarerekē me te moroiti-mata, me tapiri te bitumen whakaehunga tere me te whakaehunga whakaehunga, ara, te bitumen whakaehunga whakarerekē.
