Ma muli o ka loaʻa ʻana o ka conductivity thermal liʻiliʻi o ka bauxite clinker a ʻoi aku ka maikaʻi o ka pale skid a me ka waiwai pale pale, hiki ke hoʻohana ʻia i ka HFST (high friction surface treatment) a i ʻole ka papa abrasion o ka hui ʻana o ka asphalt e hoʻololi a hoʻololi paha i ka aggregate i kēia manawa. Hoʻokaʻawale ʻia ʻo Bauxite clinker i ʻeono mau ʻano e like me nā ʻano mea like ʻole. ʻO ke koho ʻana o ka bauxite clinker ma ke ʻano he aggregate ʻaʻole wale no ka waiwai waiwai, akā no ka hoʻomaikaʻi ʻana i ka pili ʻana ma waena o ka aggregate a me ka asphalt, kahi makapō. Ua loiloi ʻia ka ʻōpala bauxite me ka asphalt ma ke ʻano o ka hoʻoulu ʻana i ke ʻano adsorption hydrostatic a me ka manaʻo o ka ikehu manuahi.
ʻO ka Bauxite he mineral maoli, paʻakikī loa a ʻo ia ka mea nui o nā pūhui alumini oxide (alumina), silica, iron oxides a me titanium dioxide. Ma kahi o 70 pakeneka o ka hana bauxite o ka honua i hoʻomaʻemaʻe ʻia ma o ka hana kemika bayer i alumina.
ʻO Bauxite ka mea kūpono no ka hana ʻana i ka alumina. Ma waho aʻe o nā mea nui o ka aluminika a me ke silika, ua hui pinepine ʻia ka bauxite me nā mea waiwai he nui e like me ka gallium (Ga), titanium (Ti), scandium (Sc), a me ka lithium (Li). ʻO ka hana maʻamau e hoʻokomo i nā mea waiwai nui, e hoʻolilo iā lākou i kumu kumu polymetallic. ʻO ka hoʻihoʻi ʻana i kēia mau mea koʻikoʻi hiki ke hoʻonui nui i ke kaʻina hana hana alumina me ka hōʻemi ʻana i ke kuleana ʻoihana a me ka hopena o ke kaiapuni. Hāʻawi kēia haʻawina i kahi loiloi koʻikoʻi o ka ʻenehana i hoʻohana ʻia no ka hoʻihoʻi ʻana i nā mea waiwai mai ke koena bauxite a me ka hoʻolaha ʻana i ka waiʻona i hoʻopau ʻia e hāʻawi i ka ʻike i ka hoʻohana ākea ʻana o ke koena bauxite ma ke ʻano he kumu waiwai ma mua o ka ʻōpala. ʻO ka hoʻohālikelike ʻana i nā hiʻohiʻona kaʻina hana e hōʻike ana he mea maikaʻi ke kaʻina hana hoʻohui no ka hoʻihoʻi ʻana i nā mea waiwai a me ka hōʻemi ʻana i ka ʻōpala.
