Ko te kaihoroi bitumen kua whakarereketia, mena he ngawari te whakamaramatanga, he kaihoroi bitumen. Mena ka whakaahuahia nga korero, ka taapirihia nga mea whakarereke penei i te paura rapa me etahi atu whakakī ki te kaihoroi bitumen, ka whakamahia ranei he tihorea bitumen hei aukati i nga matū matū penei i te photooxygen catalysis.

Ko te tuatahi ko te whakarereke i te hanganga rauropi o te kaihoroi bitumen, ko te tuarua ko te whakamahi i nga rawa whakarereke hei whakakoi i te kaihoroi ki tetahi hanganga whatunga mokowhiti, na reira ka pai ake te mahi. Ko te nuinga o nga kaihoroi bitumen kua whakarereketia ko te rapa puia me te thermoplastic polyurethane elastomer kua whakarereketia te tihorea bitumen, te kirihou me te peita anti-waikura kua whakarerekētia te tihorea bitumen me te polymer whakarerekētia te tihorea bitumen. I tenei wa, he tino whanui ano tana tono.
Ko nga taputapu whakangao bitumen, tae atu ki te matauranga, ko nga waahanga matua e whai ake nei: He taika whakamahana tere: he mana whakahaere pāmahana aunoa, he punaha tohanga me te punaha horoi. Pouaka Thermostatic: Ka taea e ia te whakahaere i te mana pāmahana aunoa, he tohu mana mamao mita taumata wai, me te whakaurunga me te whakaurunga aukati. Te inenga bitumen a-ringa me te punaha kawe waka: ka taea te whakaputa aunoa i te uara rerenga katoa ki te whakapumau i te uara tatūkē, ka mutu te tukunga i roto i te punaha whakahaere. Rubber paura inenga me te manatoko pūmanawa pūnaha kawe waka: ka taea te whakaputa aunoa i nga tawhā uara rere tatūkē me te whakamutu haaputuputuraa i roto i te pūnaha whakahaere. Whakaranu tank: whakahaere pāmahana aunoa, te taumaha e tohu ana i te mita taumata wai.
Pūnaha whakahaere: Ko nga momo aunoa me nga momo a-ringa ka whakamahia tahi me te whakamahi tahi me tetahi. I tua atu, ka taea te whakahaere mamao ki te whakahaere i tana hanganga punaha me te whakaurunga.
