ʻO ka wehewehe a me ka hoʻohana ʻana i ka ʻenehana slurry sealing i ke kūkulu ʻana i ke alaloa
Hoʻohana ka slurry sealing i nā mea hana mechanical e hoʻohui i ka asphalt emulsified kūpono, ka wai, nā mea hoʻopiha (cement, lime, lehu lele, ka pauka pōhaku, a me nā mea ʻē aʻe) a me nā mea hoʻohui e like me ka lakene i hoʻolālā ʻia i loko o kahi hui slurry a kūlike Ua paʻi ʻia. ma ka ʻaoʻao o ke alanui kumu a ua hui pū ʻia me ka ʻili alanui kumu ma o nā kaʻina hana o ka uhi ʻana, demulsification, ka hoʻokaʻawale ʻana i ka wai, ka evaporation a me ka hoʻopaʻa ʻana e hana i kahi paʻa paʻa, ikaika, ʻaʻahu a me ke sila ʻili alanui, e hoʻomaikaʻi nui i ka hana o ka ili alanui.
Ua puka mai ka ʻenehana slurry sealing ma Kelemānia i ka hopena o nā makahiki 1940. Ma ʻAmelika Hui Pū ʻIa, ʻo ka hoʻohana ʻana i ka slurry sealant helu no 60% o ka ʻeleʻele ʻeleʻele o ka ʻāina, a ua hoʻonui ʻia ke ʻano o ka hoʻohana ʻana. He kuleana ko ia i ka pale ʻana a me ka hoʻoponopono ʻana i nā maʻi e like me ka ʻelemakule, nā māwae, ka ʻoluʻolu, ka ʻoluʻolu, a me nā lua i loko o nā alapiʻi hou a me nā mea kahiko, e hoʻomaikaʻi koke ʻia ʻO nā waiwai wai wai, anti-skid, laumania a me ka ʻaʻahu o ka ʻili o ke alanui.
ʻO ka hoʻopaʻa ʻana i ka slurry kahi ʻano hana pale no ka mālama ʻana i ka papahele. He mau māwae a me nā ʻalapalapa kahiko o nā alanui asphalt. Ke hoʻohana ʻia ka ʻili, emulsified asphalt slurry sealing hui ʻia ma luna o ka papahele i loko o kahi ʻāpana lahilahi a ʻae ʻia e paʻa i ka wikiwiki e hiki ai, i hiki ke mālama ʻia ke kahua paʻa asphalt. ʻO ia ka mālama ʻana a me ka hoʻoponopono ʻana me ka manaʻo e hoʻihoʻi i ka hana o ka ʻili o ke alanui a pale i ka pōʻino hou aʻe.
ʻO ka lohi lohi a i ʻole ka haʻahaʻa haʻahaʻa i hui ʻia i ka asphalt emulsified i hoʻohana ʻia i ka papa slurry seal e pono ai ka asphalt a i ʻole polymer asphalt ma kahi o 60%, a ʻaʻole pono ka liʻiliʻi ma lalo o 55%. ʻO ka maʻamau, ʻoi aku ka maikaʻi o ka anionic emulsified asphalt i nā mea minerala a lōʻihi ka manawa e hana ai. Hoʻohana nui ʻia no nā aggregates alkaline, e like me ka limestone. Cationic emulsified asphalt he adhesion maikaʻi i nā aggregates acidic a hoʻohana nui ʻia i nā aggregates acidic, e like me ka basalt, granite, etc.
ʻO ke koho ʻana i ka emulsifier asphalt, kekahi o nā mea i loko o ka asphalt emulsified, he mea koʻikoʻi loa ia. ʻAʻole hiki i kahi emulsifier asphalt maikaʻi ke hōʻoia i ka maikaʻi o ke kūkulu ʻana akā mālama pū kekahi i nā kumukūʻai. I ke koho ʻana, hiki iā ʻoe ke kuhikuhi i nā hōʻailona like ʻole o nā emulsifiers asphalt a me nā ʻōlelo aʻoaʻo no ka hoʻohana ʻana i nā huahana pili. Hoʻokumu kā mākou hui i nā ʻano emulsifiers asphalt multi-purpose. Inā he nīnau kāu, e ʻoluʻolu e nīnau i kā mākou lawelawe mea kūʻai aku.
Hiki ke hoʻohana ʻia ka emulsified asphalt slurry seal no ka mālama pale ʻana i ka Class II a ma lalo o nā alaloa, a he kūpono hoʻi no ka papa sila haʻahaʻa, ʻaʻahu a i ʻole ka pale pale o nā ala ala hou. Hoʻohana ʻia i kēia manawa ma nā alaloa.
Ka hoʻokaʻawale ʻana o nā sila slurry:
E like me ka gradation mineral
E like me nā ʻano ʻokoʻa o nā mea mineral, hiki ke hoʻokaʻawale ʻia ka papa slurry sealing layer i ka ʻāpana sealing maikaʻi, ka papa sealing medium a me ka layer sealing coarse, i hōʻike ʻia e ES-1, ES-2 a me ES-3.
E like me ka wikiwiki o ka wehe ʻana i ke kaʻa
E like me ka wikiwiki o ka wehe ʻana i nā kaʻa[1], hiki ke hoʻokaʻawale ʻia nā sila slurry i nā sila slurry wehe wikiwiki a me nā sila slurry wehe lohi.
Māhele ʻia e like me ka hoʻohui ʻia ʻana o nā mea hoʻololi polymer
E like me ka hoʻohui ʻia ʻana o ka polymer modifier, hiki ke hoʻokaʻawale ʻia ka papa slurry sealing layer i ka slurry sealing layer a me ka slurry sealing layer i hoʻololi ʻia.
Māhele ʻia e like me nā waiwai like ʻole o ka asphalt emulsified
Hoʻokaʻawale ʻia ka papa hoʻopaʻa slurry i ka slurry sealing layer maʻamau a hoʻololi ʻia ka slurry sealing layer e like me nā waiwai like ʻole o ka asphalt emulsified.
Māhele ʻia e like me ka mānoanoa
Wahi a ka mānoanoa like ʻole, ua māhele ʻia i ka papa hoʻopaʻa hoʻopaʻa maikaʻi (ʻo ka papa I), ka ʻāpana sealing medium (ʻano II), ka papa hoʻopaʻa hoʻopaʻa paʻa (III ʻano) a me ka papa hoʻopaʻa paʻa (IV type).
