Slurry seal ndeye kushandisa michina michina kusanganisa zvakakodzera graded emulsified asphalt, coarse uye yakanaka aggregates, mvura, mafirita (simende, lime, dota renhunzi, hupfu hwedombo, nezvimwewo) uye zvinowedzera mumusanganiswa we slurry zvinoenderana nechiyero chakagadzirirwa uye zvakaenzana kupararira. iyo pamugwagwa wepakutanga. Mushure mekuputira, demulsification, kuparadzaniswa kwemvura, evaporation uye kusimba, yakanyatsobatanidzwa neyokutanga nzira yemugwagwa kuti iite dense, yakasimba, isingapfekeki uye mugwagwa wepamusoro chisimbiso, iyo inovandudza zvikuru kushanda kwemugwagwa.
Slurry seal tekinoroji yakabuda muGermany mukupera kwema1940. MuUnited States, kushandiswa kweslurry seal account ye60% yemigwagwa mitema yenyika, uye chiyero chekushandiswa chakawedzerwa. Inobata basa mukudzivirira nekugadzirisa zvirwere zvakadai sekuchembera, kutsemuka, kutsvedzerera, kunyorova, uye makomba emigwagwa mitsva neyekare, zvichiita kuti mugwagwa usapinde mvura, anti-skid, flat, uye kusapfeka kukurumidza kuvandudzwa.

Slurry chisimbiso zvakare inzira yekudzivirira yekuchengetedza yekuvaka yekumusoro kurapwa pavement. Ekare asphalt pavements kazhinji ane makatsemuka uye makomba. Kana iyo yepamusoro yakapfekwa, iyo emulsified asphalt slurry seal musanganiswa inopararira kuita mutete mutsetse panzira uye yakasimbiswa nekukurumidza sezvinobvira kuchengetedza asphalt kongiri pavement. Iko kugadzirisa uye kugadzirisa kwakanangana nekudzorera basa repavement kudzivirira kumwe kukanganisa.
Iyo inononoka-inotsemuka kana yepakati-yakasanganiswa asphalt yakasanganiswa emulsified asphalt inoshandiswa muslurry chisimbiso inoda asphalt kana polymer asphalt yemukati inosvika 60%, uye iyo shoma haifanire kunge iri pasi pe55%. Kazhinji, anionic emulsified asphalt haina kunamatira kune zvicherwa uye nguva yakareba yekuumba, uye inonyanya kushandiswa kune alkaline aggregates, senge limestone. Cationic emulsified asphalt ine yakanaka kunamatira kune acidic aggregates uye inonyanya kushandiswa kune acidic aggregates, senge basalt, granite, nezvimwe.
Kusarudzwa kweasphalt emulsifier, chimwe chezvinhu zvinosanganiswa mu emulsified asphalt, inonyanya kukosha. Iyo yakanaka asphalt emulsifier haingogone chete kuvimbisa kunaka kwekuvaka asiwo kuchengetedza mutengo. Paunosarudza, iwe unogona kutarisa kune akasiyana-siyana zviratidzo zveasphalt emulsifiers uye mirairo yekushandiswa kwezvinhu zvinoenderana. Kambani yedu inogadzira akasiyana-siyana-chinangwa asphalt emulsifiers. Kana uine mibvunzo, tapota bvunza basa redu revatengi.
Emulsified asphalt slurry seal inogona kushandiswa kudzivirira kuchengetedza kwechipiri uye yakaderera migwagwa, uye inokodzera zvakare chisimbiso chepasi, chisimbiso chekupfeka kana chekudzivirira chemigwagwa mikuru ichangovakwa. Iko zvino yava kushandiswawo mumigwagwa mikuru.
Classification ye slurry seal:
Zvinoenderana neakasiyana magiredhi ezvigadzirwa zvemamineral, slurry chisimbiso chinogona kukamurwa kuita chisimbiso chakanaka, chepakati chisimbiso uye chakaomarara chisimbiso, chinomiririrwa neES-1, ES-2 uye ES-3 zvichiteerana.
Zvinoenderana nekumhanya kwekuvhura traffic
Zvinoenderana nekumhanya kwekuvhura traffic [1], slurry chisimbiso chinogona kukamurwa kuita nekukurumidza kuvhura traffic type slurry seal uye inononoka kuvhura traffic mhando slurry seal.
Zvinoenderana nekuti polymer modifiers inowedzerwa here
Zvinoenderana nekuti mapolymer modifiers akawedzerwa here, slurry chisimbiso chinogona kukamurwa kuita slurry chisimbiso uye yakagadziridzwa slurry chisimbiso.
Zvinoenderana neakasiyana emulsified asphalt
Zvinoenderana neakasiyana emulsified asphalt, slurry seal inogona kukamurwa kuita yakajairwa slurry chisimbiso uye yakagadziridzwa slurry chisimbiso.
Zvinoenderana nehupamhi, inogona kupatsanurwa kuita yakanaka yekuisa chisimbiso layer (layer I), yepakati seal layer (rudzi II), coarse sealing layer (rudzi III) uye yakakora yekuisa chisimbiso layer (rudzi IV).
