Kune microsurfacing, yega yega musanganiswa reshiyo yakagadziridzwa kuyedza kuenderana, iyo inokanganiswa nezvakawanda zvakasiyana senge emulsified asphalt uye aggregate mhando, aggregate gradation, mvura uye emulsified asphalt huwandu, uye marudzi emamineral fillers uye additives. . Naizvozvo, pa-saiti simulation bvunzo ongororo yemasampuri emurabhoritari pasi pemamiriro einjiniya chaiwo yave kiyi yekuongorora mashandiro eiyo micro-pamusoro musanganiswa. Miedzo yakawanda inowanzoshandiswa inounzwa seinotevera:
1. Kusanganisa bvunzo
Chinangwa chikuru chekusanganisa bvunzo ndeyekutevedzera paving yekuvaka nzvimbo. Iko kuenderana kwe emulsified asphalt uye aggregates inosimbiswa kuburikidza nekuumbwa mamiriro eiyo micro-surface, uye chaiyo uye chaiyo yekusanganisa nguva inowanikwa. Kana nguva yekusanganiswa yakarebesa, nzvimbo yemugwagwa haizosviki simba rekutanga uye haizove yakavhurika kune traffic; kana nguva yekusanganisa ipfupi, kuvakwa kwepaving hakuzove kwakatsetseka. Iyo yekuvaka mhedzisiro ye micro-surfacing inokanganiswa nyore nenharaunda. Nokudaro, pakugadzira musanganiswa, nguva yekusanganiswa inofanira kuongororwa pasi pekushisa kwakashata kunogona kuitika panguva yekuvaka. Kuburikidza nenhevedzano yebvunzo dzekuita, izvo zvinokanganisa kuita kweiyo micro-pamusoro musanganiswa zvinoongororwa zvakazara. Mhedziso dzakatorwa ndedzinotevera: 1. Tembiricha, tembiricha yakakwira inogona kuderedza zvakanyanya nguva yekusanganisa; 2. Emulsifier, iyo yakakura iyo dosi ye emulsifier, iyo yakareba nguva yekusanganiswa; 3. Simende, kuwedzera simende kunogona kuwedzera kana kupfupisa musanganiswa. Nguva yekusanganiswa inotarirwa nehupfumi hwe emulsifier. Kazhinji, iyo yakawanda yakawanda, iyo ipfupi nguva yekusanganiswa. 4. Kuwanda kwekusanganiswa kwemvura, iyo yakawanda yekusanganiswa kwemvura, iyo yakareba nguva yekusanganiswa. 5. Iyo pH kukosha kweiyo sipo mhinduro inowanzoita 4-5 uye nguva yekusanganiswa yakareba. 6. Iyo yakakura yezeta inogona ye emulsified asphalt uye kaviri yemagetsi layer yegadziriro ye emulsifier, iyo yakareba nguva yekusanganiswa.
2. Adhesion test
Kunyanya kuyedza simba rekutanga reiyo micro surface, iyo inogona kunyatso kuyera yekutanga kuseta nguva. Yakakwana simba rekutanga ndiyo inodiwa kuti uve nechokwadi chekuvhura nguva kune traffic. Iyo adhesion index inoda kuongororwa zvizere, uye kuyerwa kwekunamatira kukosha kunofanirwa kusanganiswa neyakakuvadzwa mamiriro emuenzaniso kuti uone nguva yekutanga yekuisa uye yakavhurika traffic traffic yemusanganiswa.
3. Wet wheel wear test
Iyo wet vhiri abrasion test inoteedzera kugona kwemugwagwa kuramba kupera kwematayi kana pakanyorova.
Iyo yeawa imwe-yakanyorova vhiri vhiri abrasion bvunzo inogona kuona abrasion kuramba kweiyo microsurface inoshanda layer uye yekuputira zvimiro zveasphalt uye aggregate. Kurwiswa kwekukuvara kwemvura kweiyo micro-surface yakagadziridzwa emulsified asphalt musanganiswa inomiririrwa ne6-zuva yekupfeka kukosha, uye kunyura kwemvura yemusanganiswa kunoongororwa kuburikidza nekunyorova kwenguva refu. Zvisinei, kukanganisa kwemvura hakungoratidziri mukutsiviwa kweasphalt membrane, asiwo kuchinja kwechikamu chemvura kunogona kukonzera kukanganisa kumusanganiswa. Muedzo wemazuva matanhatu ekunyudzwa abrasion hauna kufunga nezvekukanganisa kwechando-kunyunguduka kwemvura pane ore munzvimbo dzinotonhora dzemwaka. Iyo chando inokwira uye kupeuka mhedzisiro inokonzerwa neiyo asphalt firimu pamusoro pechinhu. Naizvozvo, zvichibva pamazuva matanhatu kunyudzwa kwemvura kunyorova vhiri vhiri bvunzo, zvakarongwa kutora iyo yechando-thaw cycle wet wheel abrasion bvunzo kuratidza zvizere mhedzisiro yemvura pamusanganiswa weiyo micro-pamusoro.
4. Rutting deformation test
Kuburikidza neiyo rutting deformation bvunzo, iyo vhiri track yakafara deformation rate inogona kuwanikwa, uye iyo anti-rutting kugona kweiyo micro-pamusoro musanganiswa inogona kuongororwa. Iyo diki yehupamhi deformation mwero, iyo yakasimba kugona kuramba rutting deformation uye zvirinani kugadzikana kwekushisa kwepamusoro; ukuwo, akaipisisa kukwanisa kuramba rutting deformation. Chidzidzo chacho chakawana kuti vhiri track wide deformation rate ine hukama hwakajeka ne emulsified asphalt yemukati. Iyo yakakura iyo emulsified asphalt yemukati, inotonyanya kuomarara kuramba kweiyo micro-pamusoro musanganiswa. Akataura kuti izvi imhaka yekuti mushure mekunge polymer emulsified asphalt yaiswa mu simende-based inorganic binder, elastic modulus yepolymer yakadzikira zvakanyanya pane iyo simende. Mushure mekuita kwekomboni, zvimiro zvecementitious zvinhu zvinoshanduka, zvichikonzera kudzikiswa kwekuoma kwese. Nekuda kweizvozvo, vhiri track deformation inowedzera. Pamusoro pemiyedzo iri pamusoro, mamiriro akasiyana ebvunzo anofanirwa kusetwa zvichienderana nemamiriro akasiyana uye akasiyana musanganiswa ratio bvunzo dzinofanirwa kushandiswa. Mukuvaka chaiko, musanganiswa wechiyero, kunyanya kushandiswa kwemvura yemusanganiswa uye kushandiswa kwesimende, kunogona kugadziridzwa zvakakodzera zvichienderana nemamiriro ekunze akasiyana uye tembiricha.
Mhedziso: Senge tekinoroji yekuchengetedza tekinoroji, micro-surfacing inogona kuvandudza zvakanyanya kuita kwakazara kwegwagwa uye nekubvisa zvinobudirira kukanganisa kwezvirwere zvakasiyana panzira. Panguva imwecheteyo, ine mutengo wakaderera, nguva pfupi yekuvaka uye yakanaka kugadzirisa maitiro. Ichi chinyorwa chinoongorora kuumbwa kwemicro-surfacing misanganiswa, inoongorora maitiro avo pane yese, uye muchidimbu inosuma uye nekupfupikisa bvunzo dzekuita kweiyo micro-surfacing musanganiswa mune zvazvino zvirevo, zvine chirevo chakanaka chekutsvaga mune ramangwana rakadzama.
Kunyangwe tekinoroji yemicro-surfacing yawedzera kukura, inofanirwa kuramba ichitsvagirwa nekuvandudzwa kuti ivandudze tekinoroji kuti ivandudze zvirinani uye kusimudzira mashandiro akazara emigwagwa mikuru uye kusangana nezvinodiwa zvekufamba kwetraffic. Pamusoro pezvo, panguva yekuvakwa kweiyo micro-surfacing, mamiriro mazhinji ekunze ane mhedzisiro yakananga pamhando yeprojekiti. Naizvozvo, iwo chaiwo mamiriro ekuvaka anofanirwa kutariswa uye mamwe matanho ekuchengetedza esainzi anofanirwa kusarudzwa kuti ave nechokwadi chekuti iyo micro-surfacing kuvaka inogona kuitwa mushe uye kubudirira Kuvandudza maitiro ekugadzirisa.
