Kusiyana kwakukulu zinayi pakati pa microsurfacing ndi slurry sealing
Monga ife tonse tikudziwa, yaying'ono-surfacing ndi slurry kusindikiza zonse ndi wamba njira zodzitetezera, ndi njira mabuku ndi ofanana, kotero anthu ambiri sadziwa kusiyanitsa iwo ntchito kwenikweni, kotero mkonzi wa Sinoroader angafune tengerani mwayiwu Ndikuuzeni kusiyana kwa ziwirizi.
1. Yogwiritsidwa ntchito pamisewu yosiyanasiyana: Micro-surfacing imagwiritsidwa ntchito makamaka pokonza misewu yayikulu komanso kudzaza mayendedwe opepuka. Ndiwoyeneranso kumangiriza anti-slip wear amisewu yayikulu yomwe yangomangidwa kumene. Chisindikizo cha slurry chimagwiritsidwa ntchito makamaka pokonza misewu yachiwiri ndi pansi, ndipo chitha kugwiritsidwanso ntchito posindikiza misewu yatsopano.
2. Ubwino wa aggregates ndi wosiyana: kutayika kwa abrasion kwa ma aggregates omwe amagwiritsidwa ntchito popanga mawonekedwe ang'onoang'ono kuyenera kukhala osachepera 30%, omwe ndi ovuta kwambiri kuposa kufunikira kosaposa 35% pamagulu omwe amagwiritsidwa ntchito posindikiza slurry; Zophatikiza zomwe zimagwiritsidwa ntchito popanga ma micro-surfacing zimadutsa musefa wa 4.75mm Mchenga wofanana ndi mchere wopangidwa ndi mchere uyenera kukhala wapamwamba kuposa 65%, womwe ndi wapamwamba kwambiri kuposa 45% wofunikira akagwiritsidwa ntchito posindikiza matope.
3. Zofunikira zosiyanasiyana zaukadaulo: chisindikizo cha slurry chimagwiritsa ntchito mitundu yosiyanasiyana ya phula losasinthika, pomwe malo ang'onoang'ono amagwiritsa ntchito phula losinthidwa mwachangu, ndipo zotsalira zake ndi zapamwamba kuposa 62%, zomwe ndi zapamwamba kuposa chisindikizo cha slurry. Gwiritsani ntchito phula la emulsified kuposa 60%.
4. Zizindikiro za mapangidwe a zosakaniza ziwirizo ndizosiyana: kusakaniza kwa micro-surface kuyenera kukumana ndi ndondomeko yonyowa ya magudumu pambuyo poviikidwa m'madzi kwa masiku 6, ndipo chisindikizo cha slurry sichifunika; osakaniza ang'onoang'ono pamwamba angagwiritsidwe ntchito kudzaza rut, ndipo osakaniza ali ndi katundu gudumu akugudubuza chofunika 1000 The lateral kusamutsidwa chitsanzo pambuyo mayeso anali otsika kuposa 5% chofunika, pamene slurry chisindikizo wosanjikiza sanatero.
Zitha kuwoneka kuti ngakhale ma micro-surfacing ndi slurry kusindikiza ndizofanana m'malo ena, ndizosiyana kwambiri. Mukamagwiritsa ntchito, muyenera kusankha malinga ndi momwe zilili.
