Hāʻawi ke kahua hui asphalt i ka ʻoluʻolu i nā kānaka. No ke aha wau e ʻōlelo ai pēlā? No ka mea, pono e ʻike nā kānaka a pau inā makemake ʻoe e hoʻohana i ka asphalt, pono ʻoe e hoʻohana i ka wā wela, no ka mea, ʻaʻole ia e hana inā he anu, ʻaʻole hiki ke hoʻohana inā paʻakikī, no laila pono e hoʻomehana ʻia a hoʻoulu ʻia. e hoʻemi i ka pilikia i ka wā e hoʻohana ai.

E kamaʻilio mua kākou e pili ana i ke kahua hoʻohuihui asphalt. Ma ka hoʻomaopopo ʻana i kēlā me kēia mea e hiki ai iā mākou ke hoʻomaopopo maikaʻi i ke kahua hoʻohui asphalt a mākou e kamaʻilio nei i kēia lā. ʻO ka Asphalt kahi wai ʻona ʻeleʻele ʻeleʻele kiʻekiʻe viscosity i haku ʻia me nā hydrocarbons a me nā mea non-metallic o nā kaumaha molekala like ʻole. He ʻeleʻele ka ʻili a hiki ke hoʻoheheʻe ʻia i ka carbon disulfide. I ka manawa like, he wai wai ʻole ia, hoʻomaʻemaʻe a me ka anti-corrosion organic gelling material. Hiki ke hoʻokaʻawale ʻia i ʻekolu mau ʻano: asphalt tar lanahu, asphalt petroleum a me asphalt maoli. Hoʻohana nui ʻia ka Asphalt i nā ʻoihana e like me nā uhi, plastics, rubber, a me nā ala paving.
Hana ʻia ko mākou mau alanui me ka asphalt, hiki ke kapa ʻia ʻo ia he asphalt, no laila ke ʻōlelo mau nei mākou i nā alanui asphalt. He kiʻekiʻe loa ka mahana o ka asphalt i ka wā e ninini ai i nā alanui, no ka mea ma nā haʻahaʻa haʻahaʻa, ʻoi aku ka paʻakikī ma mua o ka pōhaku a ʻaʻole hiki ke hoʻohana ʻia, no laila pono ke kahua hui asphalt. ʻO nā lako hoʻohuihui asphalt ka nui o ka ʻōnaehana batching, ʻōnaehana hoʻomaloʻo, ʻōnaehana hoʻoheheʻe, ʻōnaehana kaupaona a hui pū ʻana, ʻōnaehana hoʻolako asphalt, ʻōnaehana hoʻolako pauka, silo huahana pau a me ka ʻōnaehana hoʻomalu. He wahi koʻikoʻi loa ke kahua hoʻohuihui asphalt no ke kūkulu alanui. ʻO ke kahua hui ʻo Asphalt kahi pahu piha o nā mea hana no ka hana nui ʻana o ka asphalt concrete, a hoʻohana mau ʻia kēia mea hana i ka ninini nui ʻana i nā alanui sima. Hiki iā ia ke hana i ka hui ʻana i ka asphalt, ka hui ʻana o ka asphalt kala, a me nā mea ʻē aʻe. I kēia manawa, hoʻomaopopo nā kānaka a pau i ke kahua hoʻohuihui asphalt.
