Slurry sealing na-eji n'ibu akụrụngwa mix kwesịrị ekwesị graded emulsified asphalt, keadighi rarii na ezi aggregates, mmiri, fillers (ciment, wayo, uyi uyi, nkume ntụ ntụ, wdg) na mgbakwunye dị ka e mere ruru n'ime a slurry ngwakọta na uniformly Ọ na-paved. na mbụ ụzọ elu ma na-ike jikọtara ya na mbụ ụzọ elu site na usoro nke mkpuchi, demulsification, mmiri nkewa, evaporation na solidification na-etolite a ok, ike, eyi na-eguzogide ọgwụ na okporo ụzọ elu akara, nke ukwuu mma arụmọrụ nke okporo ụzọ elu.
