Kusindikiza chifunga ndi njira yokonza misewu yokhala ndi ntchito zambiri. Amagwiritsidwa ntchito kwambiri m'misewu yokhala ndi chindapusa chopepuka kapena chocheperako kapena zinthu zotayirira. Mwachitsanzo, pamene phula la asphalt liri lotayirira, chifunga cha chifunga chimatha kuthetsa vutoli; monga pamwamba wandiweyani graded phula osakaniza pa ukalamba pockmarked pamwamba, pamwamba pa miyala chisindikizo wosanjikiza, pamwamba lotseguka-graded phula osakaniza, etc. Iwo makamaka amanena kuti pamwamba msewu wayamba kusonyeza pang'ono kutopa ming'alu. ndi kutayika kwabwino, ndipo madzi ake amalowa mwachangu. Madzi apansi amalowa mu phula losakanikirana ndi ming'alu kapena kuwonongeka kwakukulu, kuchititsa ming'alu, ming'alu, ndi ma potholes ndi malo ena oyendamo pomwe njirayo imayenda bwino.
Makina okonza chifunga chosindikizira: Malo ambiri a asphalt amakalamba mwachangu m'zaka zoyamba za 2-4 zogwiritsidwa ntchito, zomwe zimapangitsa pafupifupi 1CM wa phula pamsewu kuti ukhale wosasunthika, zomwe zimayambitsa ming'alu yoyambirira, kumasula ndi kuwonongeka kwina kwa msewu, ndi madzi oyambilira. kuwonongeka kwa msewu. Matenda, kotero zaka 2 mpaka 4 pambuyo phula kutsegulidwa kwa magalimoto ndi nthawi kukhalabe chifunga chisindikizo wosanjikiza. Iyenera kutsimikiziridwa makamaka potengera kufufuzidwa kwamatenda am'mapangidwe ndi magwiridwe antchito am'misewu, malo oyenda pansi PCI, index flatness index IRI, kuzama kwamapangidwe, kung'ambika ndi zina.
Ntchito ya fog seal layer:
(1) Zotsatira zamadzi, zomwe zimatha kuchepetsa kuwonongeka kwa madzi pamsewu;
(2) Chifunga chosindikizira chifunga chimakhala ndi mpweya wabwino ndipo chimatha kudzaza ming'alu yabwino ndi malo opanda kanthu pamsewu;
(3) Pambuyo pomanga chisindikizo cha chifunga, mphamvu yogwirizanitsa pakati pa magulu a asphalt pamwamba pa phula imatha kukulitsidwa, kukhala ngati phula la phula ndikuteteza njira yakale ya oxidized asphalt;
(4) Kumanga kwa chifunga chosindikizira kungadetse msewu, kuonjezera kusiyana kwamtundu wa msewu, ndikuwonjezera chitonthozo cha dalaivala;
(5) Basi kuchiza ming'alu m'munsimu 0.3MM;
(6) Mtengo womanga ndi wotsika ndipo moyo wautumiki wa msewu ukhoza kuwonjezedwa.
Njira zomangira ndi zodzitetezera:
(1) Galimoto yapadera yopoperapo mankhwala kapena chida chapadera chopoperapo mankhwala chosindikizira chifunga chiyenera kugwiritsidwa ntchito kupopera zinthu zosanjikiza za chifunga malinga ndi mlingo wopoperapo mankhwala.
(2) Mphepete mwa kupopera mbewu mankhwalawa poyambira ndi pomalizira nyumbayo ziyenera kutsimikizirika kuti ndi zaudongo, ndipo mafuta ofunikira ayenera kupakidwa kale pamalo oyambira ndi omalizira.
(3) Ngati kufalikira kwa mizere kapena kutayikira kwa zinthu kumachitika, ntchito yomanga iyenera kuyimitsidwa nthawi yomweyo kuti iwunikenso.
(4) Kuchiritsa nthawi ya chifunga chisindikizo cha chifunga chiyenera kutsimikiziridwa molingana ndi mtundu wa zinthu ndi nyengo, ndipo ikhoza kutsegulidwa kwa magalimoto pokhapokha zitawuma ndikupangidwa.
