ʻElua mau ʻano hoʻololi koʻikoʻi no nā pahu asphalt aila wela: ke ʻano hui ʻana o waho a me ke ʻano hui ʻana i loko. ʻO ke ʻano o ka hui ʻana o waho, ʻo ia ka hoʻomākaukau mua ʻana i kahi pahu asphalt ʻaila wela maʻamau, a laila hoʻohui i kahi mea hoʻololi polymer latex i ka pahu pahu asphalt ʻaila wela maʻamau, a hui a hoʻoulu e hana. ʻO ka emulsion polymer ka mea maʻamau CR emulsion, SBR emulsion, acrylic emulsion, etc. ʻO ke ʻano o ka hui ʻana i loko, ʻo ia ka hui mua ʻana i ka pāpaʻi, ka plastik a me nā polymers ʻē aʻe a me nā mea hoʻohui ʻē aʻe i loko o ka asphalt wela, a laila e hui like me ka hoʻopili pono ʻana ma waena o ka polymer a me ka asphalt e loaʻa ai ka polymer-modified asphalt, a laila hele i ke kaʻina hana emulsification. No ka hana ʻana i ka emulsion asphalt i hoʻololi ʻia, ʻo ka polymer i hoʻohana mau ʻia i ke ʻano hui ʻana i loko ʻo SBS. Inā hoʻoulu ʻia ka mea asphalt a kū i ka manawa like, e hoʻomaʻemaʻe i ka ʻili o ka pahu hoʻoulu, hoʻohui i ka wai maʻemaʻe, a holoi i ka palaki. A laila, kahili i ka wai, me ka hoʻomanaʻo ʻana ʻaʻole pono e hōʻuluʻulu ʻia ka wai i loko o ka bākeke i mea e pale ai i ke ʻano o ka hoʻololi ʻana, a i ʻole nā ​​ʻanuʻu e like me ke kahua e hoʻoulu ai i ka pala. I ka wā e hoʻohana ai, pono nā mea a pau e hoʻolohe i nā ʻanuʻu liʻiliʻi e pale aku i ka paheʻe pono ʻole i ka hana ʻana o ka mīkini.

ʻO ka ʻike hana o ka pahu asphalt aila wela:
He ʻokoʻa loa ka ʻili o ka ʻili o nā pahu asphalt aila wela a me ka wai, ʻaʻole hiki ke hui pū kekahi me kekahi i nā mahana maʻamau a kiʻekiʻe paha. Ke hoʻokau ʻia ka mīkini pahu asphalt pahu wai wela i nā hopena mechanical e like me ka centrifugation wikiwiki, ʻohi, a me ka hopena, hoʻohuli ka mīkini ʻaila ʻaila wela i loko o nā ʻāpana me ka nui o 0.1 ~ 5 μm, a ua hoʻopuehu ʻia i loko o nā ʻāpana me nā surfactants ( emulsifiers-stabilizers) I loko o ka wai, no ka mea, hiki ke kuhikuhi ʻia ka emulsifier ma luna o ka ʻili o Jiangxi emulsified asphalt machinery particles, hoʻemi ia i ka interfacial tension ma waena o ka wai a me ka asphalt, e ʻae i nā ʻāpana asphalt e hana i kahi ʻōnaehana paʻa i ka wai. He aila-i-wai ka mīkini pahu asphalt aila wela. o ka emulsion. He ʻeleʻele ʻeleʻele kēlā ʻōnaehana hoʻopuehu, me ka asphalt e like me ka pae i hoʻopuehu ʻia a me ka wai ma ke ʻano hoʻomau, a hauʻoli i ka wai maikaʻi ma ka lumi wela. Ma kahi ʻano, hoʻohana ka mīkini pahu asphalt ʻaila wela i ka wai e "hoʻoheheʻe" i ka asphalt, no laila e hoʻoponopono ʻia ka wai o ka asphalt.
Hana ʻia ka pahu pahu asphalt ʻaila wela e ka hoʻoheheʻe wela i ka asphalt kumu a me ka hoʻopuʻi ʻana i nā ʻāpana asphalt māmā i loko o kahi ʻano wai i loaʻa i kahi emulsifier e hana i kahi mea asphalt wai. Hoʻohana ʻia ka pahu pahu asphalt sima ʻaila wela i loko o ke ʻano hana kūkulu ʻana i ka papa ballastless track me ka cationic thermal oil asphalt tank. Ma muli o ka maʻalahi a me ka lōʻihi o ka ciment thermal oil asphalt tank mortar, hoʻohana pinepine ʻia nā polymers e hoʻololi i ka asphalt.
