Parizvino, migwagwa mizhinji ine asphalt, iyo ine zvakawanda zvakanakira uye inobatsira kupfuura migwagwa yesamende. Naizvozvo, mota zhinji dzakakosha dzekugadzira asphalt dzakatorwa kuti dzibatsire mukugadzira nekugadzirisa migwagwa. Iyo emulsified asphalt slurry sealing tekinoroji ndeimwe yeasphalt nzira tekinoroji, uye slurry yekuisa chisimbiso rori inokonzeresa iyo chaiyo kuvaka inoderedza zvakanyanya kuoma kwekushandisa tekinoroji iyi.
Iyo emulsified asphalt slurry sealing rori chinhu chakakosha chekugadzira slurry sealing kuvaka. Inosanganisa uye inosanganisa akati wandei zvigadzirwa senge zvakakwenenzverwa giredhi zvicherwa, mafirita, asphalt emulsion uye mvura zvinoenderana neimwe yakagadzirirwa reshiyo kugadzira Muchina unoumba yunifomu slurry musanganiswa uye unoiparadzira munzira zvichienderana nehupamhi hunodiwa uye hupamhi. Maitiro ekushanda anopedzwa nekuenderera mberi nekubatisa, kusanganisa uye kugadzira mota yekuisa chisimbiso ichifamba. Chimiro chayo ndechekuti yakasanganiswa uye yakarongedzwa munzira yemugwagwa pane yakajairika tembiricha. Naizvozvo, inogona kuderedza zvakanyanya kuwanda kwevashandi, kukurumidza kufambira mberi kwekuvaka, kuchengetedza zviwanikwa uye kuchengetedza simba.
Zvakanakira slurry yekuisa chisimbiso tekinoroji: Emulsified asphalt slurry sealing layer musanganiswa weslurry wakagadzirwa neakakodzera giredhi zvicherwa, emulsified asphalt, mvura, mafirita, nezvimwewo, yakasanganiswa mune imwe chikamu. Maererano nehupamhi hwakatarwa (3-10mm) inopararira zvakaenzana mumugwagwa wemugwagwa kuti iite chidimbu chitete cheasphalt surface treatment. Mushure mekuita demulsification, kugadzika kwekutanga, uye kusimba, kutaridzika uye basa rakafanana nepamusoro peiyo yakatsetseka-grained asphalt kongiri. Iyo ine mabhenefiti ekuvaka kuri nyore uye nekukurumidza, mutengo wakaderera wepurojekiti, uye kuvakwa kweMugwagwa wekanzuru hakukanganise mvura, uye kuvaka dhizaini kwebhiriji kune huremu hushoma hwekuwedzera.
Mabasa e slurry sealing layer ndeaya:
l. Isingapindi mvura: Musanganiswa weslurry unonamira panzira kuti uite dense surface layer, iyo inodzivirira mvura nechando kubva pakupinda mu base layer.
2. Anti-skid: Ukobvu hwepaving hwakatetepa, uye iyo yakakora yakagovaniswa zvakaenzana pamusoro pechiso kuti iite yakanaka yakakasharara nzvimbo, inovandudza iyo anti-skid kuita.
3. Kupfeka kupikisa: Kugadziriswa slurry seal / micro-surfacing kuvaka inovandudza zvikuru kusungirirwa pakati pemulsion nedombo, anti-flaking, high-temperature kugadzikana, uye kuderera-kupisa shrinkage cracking resistance, kuwedzera hupenyu hwebasa remugwagwa. .
4. Kuzadza: Mushure mekusanganiswa, musanganiswa uchange uri mune slurry state ine mvura yakanaka, iyo inobata imwe basa mukuzadza kuputika uye kuenzanisa nzira yemugwagwa.
