ʻO ka asphalt emulsified he emulsion asphalt kahi e hui pū ʻia ai ka asphalt paʻa me ka wai ma o ka hana ʻana o nā surfactants a me nā mīkini e hana i kahi wai ma ka lumi wela a hiki ke hoʻohana pololei ʻia me ka ʻole o ka wela. Ke hoʻohālikelike ʻia me ka asphalt, ʻo ka asphalt emulsified ka mālama ʻana i ka ikehu, pili kaiapuni, a maʻalahi hoʻi e hoʻohana.
I nā makahiki i hala iho nei, ua hoʻohana ʻia ka asphalt emulsified i nā ʻoihana he nui. Kūkākūkā: nā alahaka a me nā culverts, ke kūkulu ʻana i ke alanui a me ka mālama ʻana, ke kūkulu hale, ka hoʻomaikaʻi ʻana i ka lepo, ka hoʻopaʻa ʻana i ke one wao nahele, ka hoʻokū ʻana o ka pali, metala anti-corrosion, nā moena alanui kaʻaahi, etc.
ʻO ka hana nui o ka asphalt emulsified i loko o nā culverts alahaka he wai wai. ʻElua mau ʻano o ka hoʻohana ʻana: ka pīpī a me ka palu ʻana, hiki iā ʻoe ke koho e like me ke kūlana kikoʻī.
Ma ka hana alanui a me ka malama ana. I nā pavements hou, hoʻohana ʻia ka emulsified asphalt i loko o ka papa permeable, ka papa hoʻopili, ke sila slurry a me ka ʻiliʻili hoʻokahi seal wai. Ma keʻano o ka mālama palekana, hoʻohanaʻia ka asphalt emulsified i nā slurry seals, micro surfacing, fine surfacing, cape seals, etc. ʻO keʻano hana kūikawā e hoʻohana i nā lako hana kūikawā.
Ma ke ʻano o ke kūkulu ʻana i ka wai, ʻo ka hoʻopuʻi ʻana a me ka pena ʻana ke ʻano nui.
