Ma lalo o ke kūlana o ka hoʻomau mau ʻana o nā ʻoihana like ʻole, ua hoʻomohala hou ʻia ka mea kanu bitumen emulsion. ʻIke mākou ʻo ka bitumen emulsion he emulsion ka wai ma ka lumi wela i hana ʻia e ka hoʻopuehu ʻana i ka asphalt i loko o ka pae wai. Ma ke ʻano he ʻano mea alanui hou, mālama ʻo ia ma mua o 50% o ka ikehu a me 10% -20% o ka asphalt i hoʻohālikelike ʻia me ka asphalt wela maʻamau, a ʻoi aku ka liʻiliʻi o ka pollution kaiapuni.

Ma ke ʻano o ke ʻano o kēia manawa, hoʻohana nui ʻia nā mea hana bitumen emulsion i nā ʻenehana hou a me nā kaʻina hana no ka mālama pale ʻana, e like me ke sila o ka fog, slurry seal, micro-surfacing, ka hoʻohou hou ʻana, ke sila pōhaku i ʻoki ʻia, ka hui ʻana a me nā mea pale anu. ʻO ka hiʻohiʻona nui loa o nā mea hana bitumen emulsion ʻo ia ka hiki ke mālama ʻia ma ka lumi wela, a ʻaʻohe pono e wela iā ia i ka wā e hoʻopuʻi a hui pū ʻia, ʻaʻole pono e wela i ka pōhaku. No laila, hoʻomaʻamaʻa loa ia i ke kūkulu ʻana, pale aku i nā kuni a me nā ʻōpala i hoʻokumu ʻia e ka asphalt wela, a pale aku i ka fumigation o ka mahu asphalt i ka wā e paʻi ai i nā huila wela kiʻekiʻe.
