Nui nā ʻano asphalt ma ka mākeke, no laila pehea ka nui o kā mākou ʻike e pili ana i ke kumu hana o ka asphalt rubber? E nānā pū kākou.
ʻO Rubber asphalt kahi mea hoʻopili asphalt i hoʻololi ʻia i hana ʻia e ka hana mua ʻana i ka ʻōpala ʻōpala mua i loko o ka pauka lāʻau, a laila hoʻohui ʻia e like me ke ʻano o ka lākiō koʻikoʻi a maikaʻi, hoʻohui i nā ʻano mea hoʻololi polymer kiʻekiʻe, a me ka hoʻoheheʻe ʻana a me ka pehu ʻana me ka asphalt matrix. ma lalo o nā kūlana wela kiʻekiʻe (ma luna o 180 ° C) me ka hui piha. Hoʻomaopopo maʻamau ʻo ia he asphalt me ​​ka hoʻohui ʻia o ka lāʻau. ʻO ka asphalt Rubber he paʻa wela kiʻekiʻe, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, anti-old, anti-fatigue, a me ka pale ʻana i ka wai. He mea hoʻohana ʻia i loko o ka papa hoʻoluhi koʻikoʻi a me ka ʻili o nā hale alanui.

ʻEkolu manaʻo kaulana o "rubber asphalt": "dry method" rubber asphalt, "wet method" rubber asphalt, a me "asphalt depot mixing method" rubber asphalt.
(1) 'O ke ala malo'o, 'o ia ka ho'ohui 'ana i ka pauda lā'au me ka aggregate mua, a laila ho'ohui i ka asphalt no ka hui 'ana. ʻO kēia ʻano hana
ʻo ka manaʻo ʻana i ka pauda lāʻau ma ke ʻano he ʻāpana o ka hui, akā ma ka maʻamau ʻaʻole hiki ke kiʻekiʻe loa ka nui o ka pauda. Hoʻohana ʻia kēia ʻano hana.
(2) "Wet method" rubber asphalt ka hui 'ana i kekahi nui o ka pauda rubber me ka asphalt ma mua, a hana i ka wela ki'eki'e e hana i hui me kekahi mau waiwai. ʻO ia ke ala i hoʻohana nui ʻia no ka hana ʻana i ka asphalt rubber.
(3) ʻO ka "Asphalt Depot Mixing Method" e pili ana i ka hui ʻana o ka pauka ʻōpala me ka asphalt wela i loko o kahi hale hoʻomaʻemaʻe a i ʻole ka asphalt depot, a laila hāʻawi ʻia i kahi kahua hui ʻana i ka asphalt a i ʻole kahua kūkulu. Hiki ke manaʻo ʻia ʻo "Asphalt depot mixing method" ma ke ʻano he ʻano hana "wet method", akā ʻaʻole i ʻoi aku ka nui o ka hoʻohana ʻana i ka pauka ʻōpala ma mua o 10%, ʻoi aku ka haʻahaʻa o ka hoʻohana ʻana i ka pauka, a ʻoi aku ka viscosity ma mua o ka asphalt rubber. ("ʻano pulu" hana). ʻAʻole hiki i ka hui ʻia ke hoʻokō i ka hana like me ka hui ʻana i ka asphalt rubber.
He aha nā mea maikaʻi o ka asphalt rubber i hoʻohālikelike ʻia me ka asphalt maʻamau?
1. Anti-reflective māwae
I loko o ka papa hoʻoheheʻe koʻikoʻi o ka asphalt, ua hoʻopaʻa paʻa ʻia ka nui o ka asphalt me ​​ka ʻiliʻili o ka nui o ka nui o ka nui e hana i kahi papa hana noʻonoʻo ma kahi o 1cm mānoanoa. ʻO nā māwae like ʻole o ka papa wai-paʻa a i ʻole ka papa sima kahiko e paʻakikī ke komo i kēia papa, hiki ke pale pono i ka noʻonoʻo ʻana o nā māwae.
2. Anti-wai poino
Nui ka nui o ka asphalt rubber (2.3kg/m2), a e hana ʻia kahi kiʻi ʻoniʻoni asphalt ma kahi o 3mm mānoanoa ma ka ʻili o ke alanui, hiki ke pale i ka wai ua mai ke komo ʻana i lalo a pale i ka moena alanui. ʻO ka lua, i ka wā e hoʻoheheʻe ai i ka hui ʻana i ka asphalt ma luna o ia mea, e hoʻoheheʻe ʻia ka asphalt asphalt ma luna o ka ʻōpala asphalt stress absorption layer no ka lua o ka manawa, a ma hope o ka hoʻopili ʻia ʻana o ka ʻili o ke alanui, e hoʻopiha piha ʻo ia i ke āpau ma lalo o ka hui ʻili. , ma laila e hoʻopau ai i ka hiki ke mālama i ka wai ma waena o nā papa a pale i ka pōʻino wai.
3. Ka hopena pili
ʻO ka asphalt Rubber he viscosity ikaika loa. Hiki ke hoʻopili ʻia a hoʻopaʻa ʻia i ka papa wai-paʻa a i ʻole ke kahua sima kahiko me ka paʻa paʻa, a laila e pāʻani ana i kahi hana paʻa me ka ʻili o ke alanui.
