Na te whanaketanga tere o te hanga huarahi nui, Ko te pikinga o te tono mo te bitumen, te paera bitumen, te peera bitumen ranei te mea tino rongonui ki te whakakii bitumen na te haumaru me te waatea.

Ko te bitumen parare mo te kawe ngawari, He ngawari ki te penapena me etahi atu waahanga e whakamahia nuitia ana. Otirā, ko te bitumen kawemai whai hua nui e whakamahia ana i roto i nga rori teitei ko te nuinga o te ahua o te paera. Me tere rewa tenei, Tangohia te oko,te miihini whakakao bitumenhe kaha ki te aukati i te koroheketanga bitumen.

Hydraulic-Drummed-Bitumen-Decanter

Ko te momo BD-raupapate pounamu bitumen pahūmiihini  i whakawhanakehia e to taatau kamupene he hanganga whakauru whakamahana-whaiaro. Ma te whakamahi i te kaitahu diesel hei puna wera, De-barreling bitumen e te hau wera me te whakawhiti wera hinu whakawera pereti, te whakarewa, te whakamahana, Ka taea e te taputapu te whakapumau i te kounga o te whakawera bitumen,
Te kaha o te waiariki teitei, Ko te tere tangohanga Bitumen he tere, Kei a ia nga ahuatanga o te kaha o te waiariki, te tere tere tango bitumen, te iti o te mahi, te kore poke, te utu taputapu iti, te waahi iti me te kawe waka. Ko te nuinga o te miihini whakakorikori uku uku he pouaka kore-paera, he mea hiki, he hiko wai, he tank takahuri, he tahu tahu, he ruuma whakawera, he punaha whakamahana rewharewha, he punaha whakamahana hinu hinu, he papu bitumen me te punaha paipa, te whakahaere pāmahana aunoa. Pūnaha, pūnaha whakahaere aunoa taumata wai, pūnaha whakahaere hiko, me ētahi atu Ka mau nga waahanga katoa ki runga i te tinana o te taputapu tango oko hei hanga i te hanganga kotahitanga.

Ko te hanganga whakauru whakamahana-whaiaro, te whakarewatanga o te mirumiru wera-rangi me te hangarau hurihuri o te bitumen barrel i roto i nga taputapu bitumen de-barreling ko nga hangarau hou o to taatau kamupene. Ko te miihini whakauru whakamahana-whaiaro e whakakotahi pai ana i te oumu hinu whakamahana wera i whakamahia i roto i nga taputapu tawhito me te tinana o nga taputapu whakaheke i te raima. Ko te nuinga o nga taputapu taputapu ka whakahekehia, ka tino heke te haumi taputapu, ka tiakina te waahi e nohoia ana e nga taputapu me te utu whakawhiti mo te whakawhiti. Ka whakanohohia te ruuma wera ki roto i te tinana o te taputapu, ka tino whakaiti i te mate wera me te whakapai ake i te whakamahinga wera.
