I nā makahiki i hala iho nei, ua hoʻoikaika ikaika ʻo Iran i kāna hoʻopukapuka ʻoihana ponoʻī a me ke kūkulu ʻana i nā alanui i mea e hoʻomohala ai i kāna ʻoihana, e hāʻawi i nā manaʻo ākea a me nā manawa kūpono no ka hoʻomohala ʻana i nā mīkini hana a me nā lako hana o Kina. He kumu kūʻai maikaʻi kā kā mākou hui ma Iran. ʻO ka mea kanu asphalt mixing, bitumen emulsion mea kanu mea kanu, slurry sealing kaʻa a me nā mea hana asphalt i hana ʻia e Sinoroader ua loaʻa maikaʻi ʻia e ka mākeke Iran. ʻO nā kaʻa slurry sealing ʻelua i kauoha ʻia e kā mākou hui Iranian agent i ka hoʻomaka ʻana o ʻAukake ua hana ʻia a nānā ʻia, a ua mākaukau e hoʻouna ʻia i kēlā me kēia manawa.

ʻO ka slurry sealing truck (a kapa ʻia ʻo Micro-Surfacing Paver) he ʻano mea hana mālama alanui. He mea hana kūikawā i hoʻomohala mālie e like me nā pono o ka mālama alanui. Kapa ʻia ka kaʻa hoʻopaʻa slurry ʻo ke kaʻa slurry sealing no ka mea ua like ka hui, bitumen emulsified a me nā mea hoʻohui i hoʻohana ʻia me ka slurry. Hiki iā ia ke ninini i ka hui ʻana o ka asphalt paʻa e like me ke ʻano o ka ʻili o ke kahua paʻa kahiko, a hoʻokaʻawale i nā māwae ma ka ʻili o ke kahua kaʻa mai ka wai a me ka ea e pale ai i ka ʻelemakule hou o ke kahua.

ʻO ka slurry sealing truck he hui slurry i hoʻohui ʻia e ka hui ʻana i ka aggregate, emulsified bitumen, ka wai a me ka mea hoʻopihapiha e like me kekahi ratio, a hoʻolaha like ʻia ma ka ʻili o ke alanui e like me ka mānoanoa i kuhikuhi ʻia (3-10mm) e hana i ka hoʻokuʻu ʻana i ka bitumen. TLC. Hiki i ka slurry sealing kaʻa ke ninini i ka hui lōʻihi e like me ke ʻano o ka ʻili o ka papahele kahiko, hiki iā ia ke hoʻopaʻa pono i ka papahele, hoʻokaʻawale i nā māwae ma luna o ka wai a me ka ea, a pale i ka pavement mai ka ʻelemakule. No ka mea, ua like ka hui, bitumen emulsified a me nā mea hoʻohui i hoʻohana ʻia e like me ka slurry, ua kapa ʻia ʻo ia ka slurry sealer. ʻAʻole wai ka slurry, a ʻo ka ʻili o ke alanui i hoʻoponopono ʻia me ka slurry he pale-pale a maʻalahi i nā kaʻa e holo.

Aia ʻo Sinoroader ma Xuchang, kahi kūlanakauhale mōʻaukala a me ka moʻomeheu. He mea hana mea hana alanui e hoʻohui ana i ka R&D, ka hana, ke kūʻai aku, ke kākoʻo ʻenehana, ka halihali moana a me ka ʻāina a me ka lawelawe ma hope o ke kūʻai aku. Hoʻokuʻu aku mākou ma kahi o 30 mau pūʻulu o nā mea kanu hui asphalt, Micro-Surfacing Pavers / Slurry Seal Trucks a me nā mea hana alanui ʻē aʻe i kēlā me kēia makahiki, i kēia manawa ua laha aku kā mākou lako i nā ʻāina ʻoi aku ma mua o 60 a puni ka honua.
