Emulsion bitumen ye micro surfacing ndiyo inosunga zvinhu zvekuvaka micro surfacing. Chimiro chayo ndechekuti inoda kusangana nenguva yekusanganiswa nedombo uye nguva yekuvhura yetraffic mushure mekunge paving yapera. Kutaura zviri nyore, inosangana nenyaya mbiri dzenguva. Nguva yekusanganisa inofanirwa kukwana, uye kuvhurwa kwetraffic kunofanirwa kunge kuri kukurumidza, ndizvo zvese.
Ngatitaure nezve emulsion bitumen zvakare. Emulsion bitumen inonzi mafuta-mu-mvura bhitumeni emulsion. Icho chinhu chakafanana viscous liquid pakamuri tembiricha. Inogona kuiswa inotonhora uye haidi kupisa. Iyo inochengetedza simba uye inochengetedza zvakatipoteredza. Emulsion bitumen yakakamurwa kuita marudzi matatu zvichienderana neakasiyana bhitumeni emulsifiers anoshandiswa mukugadzira: kutsemuka zvishoma nezvishoma, kutsemuka kwepakati, uye kukurumidza kutsemuka. Iyo emulsified bhitumeni inoshandiswa mukuvaka micro-surfacing inononoka kutsemuka uye nekukurumidza kuseta cationic emulsion bitumen. Rudzi urwu rwebhitumeni remulsion rinogadzirwa nekushandisa zvishoma nezvishoma kutsemuka uye nekukurumidza kuseta bhitumini emulsifier uye kuwedzera mapolymer modifiers. Inogona kuwana yakakwana nguva yekusanganisa uye nekukurumidza kuseta maitiro. Iko kunamatira pakati pe cations nedombo kwakanaka, saka iyo cationic mhando inosarudzwa.

Slow cracking uye fast setting emulsion bitumen inonyanya kushandiswa kudzivirira kugadzirisa mugwagwa. Ndokureva kuti, inoshandiswa kana iyo base layer yakanyatso kurongeka asi iyo yekumusoro layer yakakuvadzwa, senge nzira yemugwagwa yakatsetseka, yakatsemuka, yakapwanyika, nezvimwe.
Nzira yekuvaka: Pfaya musara wemafuta ekunamira kutanga, wobva washandisa micro-surfacing/slurry seal paver kuti pave. Kana nzvimbo yacho iri diki, kusanganisa nemaoko uye paving emulsion bitumen nedombo zvinogona kushandiswa. Kuenzanisa kunodiwa mushure mekugadzira. Inogona kushandiswa zvakajairwa mushure mekumirira kuti nzvimbo yacho iome. Inoshanda kune: yakaonda layer yekuvaka mukati me1 cm. Kana ukobvu huchida kudarika 1 cm, hunofanira kuiswa muzvikamu. Mushure mekunge imwe nhanho yakaoma, iyo inotevera inogona kugadzirwa. Kana paine matambudziko panguva yekuvaka, unogona kubata basa revatengi kuti ubvunze!
Slow-crack uye nekukurumidza-setting emulsion bhitumeni chinhu chinosimbisa chekuisa chisimbiso che slurry uye micro-surface paving. Kunyatsotaura, pakuvaka yakagadziridzwa slurry seal uye micro-surfacing, inononoka kuputika uye kukurumidza-kuisa emulsion bhitumeni inoda kuwedzerwa ne modifier, kureva, modified emulsion bitumen.
