(4) ʻO ke kaula basalt fiber i ʻoki ʻia i ka wela maikaʻi a me ke kūpaʻa ʻana.Aia kona pae wela hana ma waena o 270 a 651 degere Celsius, a hiki iā ia ke hoʻomau i ke kūpaʻa ma nā wahi wela kiʻekiʻe.Hiki iā ia ke pale i ka paheʻe ʻana o nā mea mineral i loko o ke kaʻa, hoʻomaikaʻi i kona kūpaʻa, a hoʻomaikaʻi maikaʻi i ka pale ʻana i ka wela kiʻekiʻe i ka rutting strain of asphalt concrete pavement.
Eia kekahi, ʻoi aku ka maikaʻi o ke kūpaʻa haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi no ka hoʻomaikaʻi ʻana i ke kūpaʻa haʻahaʻa haʻahaʻa o ka asphalt concrete pavement.
ʻO ka hoʻohui ʻana i ke kaula basalt fiber i ʻoki ʻia i ka pāpaʻi asphalt hiki ke hoʻomaikaʻi i ke kūpaʻa hopena, ke kū ʻana o ka ʻūhā, a me nā waiwai mechanical o ke kahua paʻa asphalt.ʻO ke kikoʻī, he kuleana koʻikoʻi ka basalt fiber chopped pavement, e like me ke kūpaʻa ʻana, anti-seepage, durability, impact resistance, tensile strength, and aesthetics.
Nā ʻano hana a me ka mālama ʻana noke kaula basalt i ʻoki ʻiaʻākaʻa asphalt
(1) ʻO ka mahana hana
ʻAʻole pono e haʻahaʻa loa ka mahana o ke kūkulu ʻana i ke kaula basalt, no ka mea, e hoʻonui ʻia ka viscosity o ka asphalt.No laila, ʻoi aku ka kiʻekiʻe o ka mahana o ke kūkulu ʻia ʻana o ka basalt asphalt ʻokiʻoki pōkole ma mua o ke koʻikoʻi asphalt maʻamau.
(2) Ka hoʻomalu ʻana i ka maikaʻi o ke kūkulu ʻana
ʻO ka mana o ke kūkulu ʻana i ke ʻano o ka basalt fiber chopped strand asphalt concrete e pono e hoʻolohe i ka mana maikaʻi o ka nānā ʻana, ana, a me ke kaʻina hui ʻana o kēlā me kēia mea ʻāpana i ka basalt fiber i ʻoki ʻia.
I ke kūkulu maoli ʻana, pono e koho ʻia nā ʻano like ʻole o ka basalt ʻoki pōkole i loko o kahi ākea kūpono e like me nā koi ʻenehana.Ma muli o ka ʻike ʻole o ke kaula basalt i ʻoki ʻia iā lākou iho me nā ʻāpana ʻē aʻe a me nā mea hoʻohui, ʻaʻole e hoʻololi ka ʻike o ka fiber i ka hui ʻana o ka ʻāpana kumu.
I ka wā o ke kūkulu ʻana, pono e helu ʻia a hoʻoholo ʻia ka maikaʻi o nā mea like ʻole i loko o ka basalt fiber chopped strand reinforced concrete a hoʻoholo ʻia e pili ana i ka nui o ka hui ʻana a me ka nui o ka hui ʻana i hoʻokahi manawa.Ua aʻo ʻo He Junyong, ʻo Tian Chengyu, a me nā mea ʻē aʻe i ka ʻāpana hui maikaʻi loa o ka basalt fiber reinforced concrete ma o nā ʻano hoʻokolohua orthogonal design.ʻElima mau mea, ʻo ia hoʻi ka maʻiʻo fiber, ka lākiō sima wai, ka maʻiʻo lehu lele, ka ratio one, a me ka hoʻohana ʻana i ka wai, ua koho ʻia ʻo ia nā kumu nui o ka hoʻokolohua.
Hōʻike ka Papa 2 i nā ʻāpana hui maikaʻi loa o ka pāpaʻi i hoʻoikaika ʻia i ka fiber basalt i loaʻa ma o nā hoʻokolohua.
Ua hōʻike ʻia nā hoʻokolohua ʻoi aku ka kiʻekiʻe o ka lākiō o ka basalt fiber i ʻoki ʻia i ke kaula, ʻoi aku ka maikaʻi o ka hopena kūʻē ʻana o ke kaʻa, ma 1.2kg/m ³ I loko o kahi kikoʻī, piʻi ka ikaika compressive o ka ʻōpala me ka hoʻonui ʻana o ka ʻike o ka fiber basalt. ʻoki ʻia ke kaula, a laila emi iho a piʻi ma ke ʻano ʻāwili.
(3) ʻO ke kaʻina hānai a me ke ʻano
Ma ke kaʻina hui ʻana oke kaula basalt i ʻoki ʻiaasphalt concrete, pono e noʻonoʻo ʻia ke kaʻina hānai ʻana o ke kaula basalt fiber i ʻoki ʻia.I ka hoʻohana ʻana, e hoʻohui i ke kaula basalt i ʻoki ʻia me nā mea hoʻohui e like me ke one a me ka pōhaku.ʻOi aku ka maikaʻi e hoʻohui i ke one a me ka pōhaku i ka manawa like.Hoʻohui i ke kaula basalt fiber i ʻoki ʻia i ke one, a laila hoʻohui i ka asphalt a me ka hui pulu a hoʻoulu.
Hiki ke hoʻokaʻawale ʻia ke ʻano hoʻohui fiber i ka hoʻohui manual a me ka hoʻohui aunoa.ʻO ka hoʻohui artificial e pili ana i ka hoʻohui lima ʻana i ke kaula basalt fiber i ʻoki ʻia i kaupaona ʻia ma hope o ka hoʻohui ʻia ʻana o nā mea wela i ka pahu hui.Eia nō naʻe, ʻo kona mau hemahema he kiʻekiʻe o ka hana, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, a me ka pono e hoʻolōʻihi i ka manawa hui e like me ke kūlana maoli e hōʻoia i ka hoʻopuehu ʻia ʻana o nā fibers i loko o ka asphalt concrete.
ʻO ka hānai ʻakomi e pili ana i ka hoʻohana ʻana i kahi mea hānai fiber basalt e ana ʻakomi i ka nui o nā mea e hoʻohui ʻia a hoʻokomo i loko o ka ipu hao me ka hui wela o ka mea hui.Loaʻa i ka fiber feeder nā mea maikaʻi e like me ke ana ʻana i ka mīkini, pre crushing, a me ka mīkini lawe ʻana i ka ea, a he maʻalahi, wikiwiki, a pololei hoʻi nā hana hoʻohui fiber.Ma nā noi kūpono, pono e koho ʻia nā ala kūpono ma muli o ke kūlana kūkulu maoli.
(4) E mālama i ka paving
ʻO ka mea mua, pono e nānā i ka maʻemaʻe o ka papa paving;A laila e hoʻomaʻamaʻa mua i ka pā hao o ka paver i 120 degere Celsius, me ka nānā ʻana i ka wikiwiki o ka paving, e hoʻomalu iā ia ma kahi o 3 a 4 mau mika i kēlā me kēia minuke;Pono e hoʻoholo ʻia ka coefficient o ka wehe ʻana ma muli o ke kau hoʻokolokolo maoli o ka papahana;Pono e mālama ʻia ka mahana o ka paving ma 160 degere Celsius.
(5) Hoʻokumu a ho'ōla
Paʻa i hui ʻia meke kaula basalt i ʻoki ʻiaʻAʻole pono e loaʻa nā koi kūikawā i ka wā o ka hoʻoheheʻe ʻana, koe wale no ka hōʻoia ʻana i ka hoʻopaʻa piha ʻana o ke kaʻa asphalt.Pono e hoʻopili ʻia e like me ka hiki ma lalo o nā kūlana wela kiʻekiʻe.
Nā laʻana noiʻi oke kaula basalt i ʻoki ʻiama ke kahua paʻa pōhaku asphalt
ʻO ka Haining Interchange Connection Line o Jiashao Expressway (me ke kahua pavement o 20cm sima i hoʻopaʻa ʻia i ke kumu pōhaku i ʻoki ʻia a me + 6cm (AC-20C) asphalt concrete a me + 4cm (AC-16C) asphalt concrete) a me ke alanui 08 Provincial ua ʻae ʻia e ka Haining Municipal Science and Technology Bureau.I mea e 'imi ai i ka 'epekema a me ka pono hana e hoʻomaikaʻi i ke ala kū'ē i ka rutting, e hōʻoia i ka palekana a me ka laumania o ke ala nui, a hooikaika i ka mālama 'ana i nā maʻi rutting ma ka maʻalahi a me ka maʻalahi, me ka pōkole manawa kūkulu a me ka haʻahaʻa mālama koina, Curing ho'āʻo. ua hana ʻia me ka hoʻohana ʻana i ke koki asphalt i hoʻololi ʻia me ke kaula basalt fiber ʻoki ʻia.
Mai ka hiʻohiʻona o ka hopena lapaʻau, ʻo ka hoʻohui ʻana o ka basalt fiber chopped strand e hoʻomaikaʻi nui i ke kūpaʻa kiʻekiʻe o ka paʻa ʻana o ka asphalt concrete pavement, hoʻonui i ka lōʻihi o ka pavement, hoʻolōʻihi i kona ola lawelawe, a hōʻemi i ka hiki ʻana o nā lua lua, e hāʻawi ana i kahi hōʻoia ikaika. no ka palekana o ke kalaiwa.
