Kukonza misewu ndi kukonza asphalt ozizira chigamba zinthu ndi kothandiza komanso yosavuta kukonza msewu. Nawa mawu oyamba mwatsatanetsatane:
1. Tanthauzo ndi kalembedwe
Zida zozizira za asphalt, zomwe zimadziwikanso kuti kuzizira kozizira, kusakaniza kozizira kwa asphalt kapena kusakaniza zinthu zozizira za asphalt, ndizinthu zomangira zomwe zimapangidwa ndi phula la matrix, zodzipatula, zowonjezera zapadera ndi zophatikiza (monga miyala). Zidazi zimasakanizidwa molingana ndi gawo lina mu zida zosakaniza za asphalt kuti apange "asphalt ozizira replenishing fluid", ndiyeno amasakanizidwa ndi aggregates kuti pomaliza apange zida zomalizidwa.
2. Mbali ndi ubwino
Zosinthidwa, osati thermoplastic kwathunthu: Chigamba chozizira cha asphalt ndi chisakanizo cha asphalt chosinthidwa, chomwe chimakhala ndi zabwino zambiri za jakisoni wachindunji komanso magwiridwe antchito apamwamba.
Kukhazikika kwabwino: Pa kutentha kwabwino, zinthu zozizira za asphalt zimakhala zamadzimadzi komanso zokhuthala, zokhala ndi zinthu zokhazikika. Ndiwo maziko azinthu zopangira zigamba zozizira.
Ntchito zosiyanasiyana: Itha kugwiritsidwa ntchito pakati pa -30 ℃ ndi 50 ℃, ndipo ingagwiritsidwe ntchito nyengo yonse. Ndikoyenera kukonza mitundu yosiyanasiyana ya misewu nyengo iliyonse komanso chilengedwe, monga phula, misewu ya konkire ya simenti, malo oimika magalimoto, mabwalo a ndege, ndi milatho. Zochitika monga malo olumikizirana, maenje amisewu yayikulu, misewu yayikulu yamayiko ndi zigawo ndi misewu yayikulu yamatauni, kukumba ndi kudzaza anthu, kubweza mapaipi, ndi zina zambiri.
Palibe Kutentha kofunikira: Poyerekeza ndi kusakaniza kotentha, zinthu zozizira za asphalt zitha kugwiritsidwa ntchito popanda kutentha, kuchepetsa kugwiritsa ntchito mphamvu komanso kutulutsa mpweya.
Kugwiritsa ntchito kosavuta: Mukamagwiritsa ntchito, ingotsanulirani zinthu zoziziritsa kuziziritsa m'maenje ndikuziphatikiza ndi fosholo kapena chida chophatikizira.
Kuchita bwino kwambiri: Chigamba chozizira cha asphalt chimakhala ndi zomatira komanso kulumikizana kwambiri, zimatha kupanga mawonekedwe onse, ndipo sizosavuta kusenda ndikusuntha.
Kusungirako kosavuta: Zinthu zozizira za asphalt zosagwiritsidwa ntchito zimatha kusungidwa zosindikizidwa kuti zigwiritsidwe ntchito.

3. Masitepe omanga
Kuyeretsa mphika: Kudziwa malo okumba dzenje, ndi mphero kapena kudula madera ozungulira. Tsukani miyala ndi zinyalala zotsalira mkati ndi mozungulira dzenjelo kuti likonzedwe mpaka malo olimba ndi olimba awonekere. Pa nthawi yomweyi, m'dzenje musakhale matope, ayezi kapena zinyalala zina. Pamene grooving, mfundo ya "square kukonza maenje ozungulira, kukonza molunjika kwa maenje okhotakhota, ndi kukonzanso maenje osalekeza" ayenera kutsatiridwa kuonetsetsa kuti maenje okonzedwawo ali ndi m'mphepete mwaukhondo.
Brushing mawonekedwe m'mphepete sealer/emulsified asphalt: Sambani mawonekedwe othandizira/emulsified asphalt mofanana pankhokwe ndi pansi mozungulira dzenje loyeretsedwa, makamaka kuzungulira dzenje ndi ngodya za dzenje. Ndalama zovomerezeka ndi 0.5 kg pa square mita imodzi kuti ziwongolere bwino pakati pa msewu watsopano ndi wakale komanso kukulitsa kusagwira kwamadzi ndi kuwonongeka kwa madzi m'malo opondapo.
Dzazani dzenje: Dzazani zinthu zoziziritsa za asphalt zokwanira m'dzenje mpaka chodzazacho chikhale pafupifupi 1.5 cm kuchokera pansi. Pokonza misewu yamatauni, kuyika kwa zida zozizira kumatha kuonjezedwa ndi 10% kapena 20%. Pambuyo podzaza, pakati pa dzenje liyenera kukhala lalitali pang'ono kuposa msewu wozungulira komanso mawonekedwe a arc. Ngati kuya kwa dzenje pamsewu waukulu kuposa 5 cm, iyenera kudzazidwa ndi zigawo ndi kuphatikizika wosanjikiza ndi wosanjikiza, ndi 3 mpaka 5 cm pa wosanjikiza kukhala koyenera.
Kuphatikizika: Pambuyo pakupanga mofanana, sankhani zida zoyenera zophatikizira ndi njira zophatikizira molingana ndi malo enieni, kukula ndi kuya kwa malo okonzera. Kwa maenje okhala ndi madera akuluakulu, chodzigudubuza chingagwiritsidwe ntchito popangana; kwa maenje okhala ndi madera ang'onoang'ono, makina opangira chitsulo angagwiritsidwe ntchito popangana. Pambuyo pa kuphatikizika, malo okonzedwawo ayenera kukhala osalala, ophwanyika opanda zizindikiro za magudumu, ndipo malo ozungulira ndi ngodya za dzenje ayenera kuphatikizika osati kumasuka. Ngati mikhalidwe ikuloleza, paver ikhoza kugwiritsidwa ntchito. Ngati makina opangira makina sakupezeka, forklift ingagwiritsidwe ntchito kukweza thumba la tani, kutsegula doko lotulutsira pansi, ndikubwezeretsanso kumanga. Pamene mukumasula zinthuzo, zikwaleni pamanja ndikuzikulunga koyamba. Pambuyo pakugudubuza, muziziziritsa kwa ola limodzi. Panthawiyi, onani kuti palibe madzi ozizira ozizira kusakaniza pamwamba kapena kulabadira chizindikiro gudumu likulu pa kugubuduza. Ngati palibe cholakwika, chogudubuza chaching'ono chingagwiritsidwe ntchito pogubuduza komaliza. Kugubuduza kwachiwiri kudzadalira kuchuluka kwa kulimba. Ngati kuchedwa kwambiri, padzakhala zizindikiro zamagudumu. Ngati nthawi yachedwa, flatness idzakhudzidwa chifukwa cha kulimba kwa msewu. Chepetsani m'mbali mwachisawawa ndipo samalani ngati pali gudumu lomamatira. Ngati pali gudumu lomamatira, chodzigudubuzacho chidzawonjezera madzi a sopo kuti azipaka mafuta kuti achotse tinthu tating'onoting'ono tachitsulo. Ngati gudumu limamatira chodabwitsa, onjezerani nthawi yoziziritsa moyenera. Pambuyo poyeretsa ndi kuphatikizika, ufa wa miyala kapena mchenga ukhoza kuwaza mofanana pamwamba, ndikusesa mmbuyo ndi mtsogolo ndi chida choyeretsera kuti mchenga wabwino ukhoza kudzaza mipata. Pamwamba pa dzenje lokonzedwanso liyenera kukhala losalala, lathyathyathya, komanso lopanda magudumu. Ngodya zozungulira dzenjelo ziyenera kulumikizidwa ndipo pasakhale kumasuka. Digiri yophatikizika ya kukonza misewu wamba ikuyenera kupitilira 93%, ndipo kuchuluka kwa kukonza misewu kuyenera kupitilira 95%.
Magalimoto otseguka: Oyenda pansi ndi magalimoto amatha kudutsa malo okonzerawo atakhazikika ndikukwaniritsa zofunikira zotsegulira magalimoto. Oyenda pansi amatha kudutsa atagubuduza kawiri kapena katatu ndikuisiya kwa maola 1 mpaka 2, ndipo magalimoto amatha kutsegukira magalimoto kutengera kuchiritsa kwa msewu.
IV. Zochitika zantchito
Zida zozizira za asphalt zimagwiritsidwa ntchito kwambiri kudzaza ming'alu ya misewu, kukonza maenje ndi kukonza misewu yopanda misewu, kupereka yankho lokhalitsa komanso lamphamvu kwambiri. Ikhoza kugwiritsidwa ntchito pa ntchito yokonza misewu pamagulu onse, monga misewu yayikulu, misewu ya m'tawuni, misewu, misewu ya dziko, misewu yachigawo, ndi zina zotero. makina omanga ndi magawo olumikizirana, komanso kuyala mizere yamapaipi ndi zochitika zina.
Mwachidule, kukonza misewu ndi kukonza asphalt cold patch material ndi chinthu chokonzekera misewu chomwe chimagwira ntchito bwino komanso chosavuta kumanga, ndipo chili ndi chiyembekezo chogwiritsa ntchito.
