Me pēhea te whakaiti i ngā utu o tētahi wheketere whakaranu hangarua wera uku me te kore e whakaiti i te kounga?
He aha ngā take e pātai ai ngā kaimahi kirimana mō ngā whare whakaranu hangarua wera uku
Mena kua tae atu koe ki tētahi whakaaturanga hanga rori i ēnei rā, kua rongo pea koe i te haruru o te whare whakaranu parapara wera . Kei te kōrerohia tēnei e te katoa—ngā kaiwhakahaere kaupapa, ngā miihini o te DOT, tae atu ki ngā taraiwa taraka i oati ki ngā ranunga parapara hou anake. Engari anei te pātai miriona tāra: ka taea e tēnei hangarau te whakaiti i te tahua me te kore e huri i tō ara hei hakari poka? Kia keri tātou kia kitea ai.
He aha tonu te "Whakamahinga Anō Wera" i roto i te Whare Hanga?
Wareware ki te kupu mō tētahi wā poto. Ko te tikanga o te hangarua wera ko te whakamahana anō i te ara uku kua whakahokia mai (RAP) me te whakaranu ki te kirikiri hou me te bitumen i roto i te pūoro kotahi . Ka puta te mahi makutu i te 150–160 °C, ka wai anō te mea here tawhito ka hanumi ki te mea hou. Ko te mutunga? He ranunga e rite ana ki te tunu kai hou engari kei roto tae atu ki te 50% o te ihirangi hangarua. He pai, āe?
Te Whārite Tāra-me-Heneti
Me kōrero tātou mō te tāki. Kei te tata ki te $700 te utu mō te tāki Virgin i te nuinga o ngā tauranga o Amerika. Whakakapia te 40% o tēnā ki te RAP, ā, kua penapenahia e koe te $280 mō ia tāki . Mō tētahi mahi whakawhiti whenua 20,000-tāni, he $5.6 miriona te whakahekenga o te utu . Ahakoa kua whakaarohia e koe te kaha whakamaroke tāpiri me te whakamahi i tētahi rongoā whakaora tinana nui ake, kei te titiro tonu koe ki te penapena rua-mati. Ka aroha tō tari pūtea ki a koe mō tēnā.
He Kino te Kounga? He Nui Ake te Kōrero a ngā Raraunga Taiwhanga i ngā Kōrero Rongoā
I whakahaerehia e ngā taiwhanga DOT motuhake i Texas me Ontario ngā whakamātautau rutting i runga i te 50% o ngā ranunga RAP i hangaia i roto i tētahi tipu whakaranu hangarua wera uku hou. I hoki mai te pumau hihiri ki te 3 200 huringa/mm , he pai ake i te iti rawa o te 2 000. I runga i te kino o te makuku, ko te ōwehenga kaha-kukui i eke ki te92 % , e eke ana ki te 80% o te whakaritenga. Whakamāoritanga: he rite tonu te roa o te ara whariki—he roa ake i ētahi wā—i ngā rori kāore anō kia whakamahia .
Te Whakawhiti Mai i te Puranga ki te Hangarua: He aha ngā Huringa kei te Pae?
I mua i tō tere ki te whakahou i tō pourewa puranga o ngā tau 1970, kia mōhio koe ki tēnei: me whai pūwero whakarara koe, me whai rohe whakamaroke rānei hei tiaki i te RAP mai i te mura tika. Ka tāpirihia hoki e koe he reti inenga whakaora me te ipu whāngai matao RAP me ngā puku auau-rerekē. Ā, me tētahi atu mea - me whakahou tō rorohiko tipu i tētahi pūmanawa hei aroturuki i ngā rohe pāmahana maha i te wā kotahi. Kia oti aua whakarerekētanga, ka taea e koe te huri i waenga i ngā ranunga tauhou me ngā ranunga hangarua i roto i te 45 meneti.
Ngā Painga Taiao e Whakaataata ai ngā Kaiwhakahaere
Ko ia tana o te RAP ka whakamahia anō e koe ka pupuri i te 0.45 tana o te CO₂ kia kore e uru ki te rangi—he rite ki te whakato i te 20 rākau. Whakareatia tēnā ki te 3 miriona tana o te RAP kua puranga kē i te US, ā, kei te kōrero koe mō te tapuwae waro o tētahi tāone rahi-waenga ka ngaro i te pō kotahi. Kei te tīmata ngā whiwhinga LEED me ngā mākete whiwhinga waro ki te utu i taua whanonga, nō reira ehara te kakariki i te tae noa—he mea ka taea te hoko.
Ngā Pūrākau Noa, Kua Whakakorea
Pūrākau 1: "He mea pango matotoru noa te RAP e ngoikore ai te ranunga."
Tūturu: Mā te wehewehenga tika me te whakatikatika hau wera rawa , ka rite te RAP ki te konganuku tauhou.
Pūrākau 2: "Kāore e taea te neke atu i te 25% RAP i ngā papa mata."
Mooni: Nō te tau 2022, i whakatūria e te Tari Tari o Missouri he mata RAP SMA 50% ki runga i te I-35—kāore he ngatata i muri i ngā hotoke e rua.
Rārangi Arowhai Tīmatanga Tere mō ngā Kaihoko Wā Tuatahi
- Me tono he whāngai RAP tere-rerekē kia eke ki te tika ±1%.
- Me tāpiri he pūoko pāmahana whero-whero ki runga i te putanga o te pahu hei ārai i te paoa kikorangi.
- Inoia he mīhini whakawhiti wera e horoi ana i a ia anō , kia kore ai koe e piki ki roto me te mīhini horoi pehanga i ia wiki.
- Whiriwhiria he whakaritenga whakahou pūmanawa e rima tau te roa ; he tere te neke o te hangarau i tēnei wāhanga.
Te Whakatūpato i te Ao o Mua: Te Huka Mahana, Ngā Whakaora-Koiora, me tua atu
Kei te werohia kētia e ngā kairangahau i roto i te Netherlands te pahuka wera i te 110 °C, ka tapahia he 12% atu te pūngao. I taua wā tonu, kei te whakakapia ngā hinu rere hinu e ahu mai ana i te pīni soya e ngā mea whakahou, e akiaki ana i ngā ihirangi hangarua ki te taha.70 % Ka taea e ngā kaiwhakamahi wawe e whakatau ana i tētahi tipu whakaranu hangarua wera uku me ngā putanga mura whakapūmau te whakauru i aua hangarau me te kore e hoko i tētahi pūtu hou. Whakaarohia tēnei hei whakapaipai i tō pūtea mō āpōpō.
Ko te Whakamutunga: He Pai te Hanga Pūtea i te Tau 2024?
Tātaitia ngā tatauranga mō tētahi tipu 200-tāne-ia-haora e whakahaere ana i te 40% RAP. Ka whakahokia mai e koe te $1.2 miriona mō te hangarua i roto i ngā marama 14 i ngā utu here o nāianei. Tāpirihia ngā whiwhinga waro, ngā utu whakawhiti whenua ururua, me te awhi hokohoko o te "kaihanga rori matomato," ā, ka heke te utu ki raro iho i te tau . Nō reira, he pono te rongonui. Ko te pātai anake e toe ana ko: kia pēhea te tere ka taea e koe te tīmata?
