Ubuchwepheshe bokuvala uphawu lwamatshe okuvumelanisa busetshenziswe kancane kancane ekhaya naphesheya. Iwubuchwepheshe bokugcina imali futhi obusebenzayo. Iloli le-synchronous gravel sealing lisetshenziselwa ukusabalalisa i-asphalt binder (i-asphalt eguquliwe, i-asphalt e-emulsified, njll.) kanye namatshe osayizi wezinhlayiyana eyodwa (evame ukusetshenziswa 4 kuya ku-6 mm, 6 kuya ku-10 mm) phezu komgwaqo ngesikhathi esisodwa, bese edlula. umshini wokugoqa isondo lenjoloba Noma ukugingqika kwezimoto kwemvelo kwakha ungqimba olugqokile lwe-asphalt gravel pavement. Ingalungisa imifantu yemigwaqo, inciphise imifantu ekhanyayo, futhi ithuthukise ukuguga. Ifilimu ye-asphalt eyenziwe phezu komgwaqo ingamelana kahle nokungena kwamanzi angaphezulu. Inesikhathi esifushane sokwakha, ubuchwepheshe obulula, nokusebenza okuqinile. Njengamanje, ungqimba lwe-synchronous gravel seal lusetshenziswa ekunakekeleni imigwaqo emikhulu, imigwaqo emikhulu evamile, imigwaqo yesifunda neyelokishi, futhi lungasetshenziswa endaweni egqoke ungqimba lwemigwaqo emisha kanye nongqimba olungezansi lophawu lwezindawo zomgwaqo eziqinisiwe. Uma izimali zokwakha ziqinile, zingasetshenziswa njengendlela yokuhamba ngezinyawo emigwaqweni emikhulu yezinga eliphansi.
Ngesikhathi senqubo ethile yokwakha, lobu buchwepheshe bugxile kakhulu kungqimba olungaphezulu, kuyilapho ungqimba olungaphezulu lokuvala kanye nongqimba olugqokile luvame ukunganakwa, okuholela ekulahlekelweni kwezinsiza. Eminyakeni yamuva nje, ubuchwepheshe obufana ne-micro-surfacing kanye ne-ultrasonic abrasion buqhubekile nokuvela. Enkambweni yokugcinwa kokuvimbela imigwaqo ye-asphalt, ubuchwepheshe bokuvala uphawu buvame ukusetshenziswa. Ubuchwepheshe obusetshenziswa ngokuvamile buhlanganisa ukumboza kongqimba oluncane olushisayo nokubandayo kanye nokuvala uphawu lokuqhekeka. izendlalelo nezinye izinhlobo eziningi. Inketho eyinhloko yobuchwepheshe bongqimba bokuvala indawo egandaywe yitiyela ungqimba oluhambisanayo lokuvala amatshe e-asphalt. Lobu buchwepheshe bungasindisa ngempumelelo izindleko zephrojekthi. Ngaphezu kwalokho, njengoba lobu buchwepheshe babusetshenziswa eFrance ekupheleni kwekhulu lama-20, buye banda ngokushesha bafinyelela e-United States naseYurophu. Amazwe, kuhlanganise nambalwa ase-Asia, e-Afrika, nase-Australia, nawo aseqalile ukusebenzisa lobu buchwepheshe emisebenzini ethile. Izibalo zibonisa ukuthi cishe amaphesenti angu-5 kuphela amaphrojekthi eYurophu angasebenzisi lobu buchwepheshe ekuvimbeleni ukulungiswa kwemigwaqo. Njengamanje, lapho usebenzisa lobu buchwepheshe bokubeka uphawu ezweni lakithi, lezi zidingo ezilandelayo kufanele zihlangatshezwe.
(1) Izidingo ezihlanganisiwe. Ukuze umelane nokuguga nokuklebhuka kwezimoto ngesikhathi sokusebenza komgwaqo onguthelawayeka, ama-aggregate omgwaqo adinga ukuba nobunzima obanele. Ikakhulukazi esimweni sokugeleza kwethrafikhi esindayo nomthwalo wemoto, ukukhethwa kokuqina okuhlanganisiwe kuba okuvelele kakhulu; i-gradation ngokuvamile ayixubene nempushana. Sebenzisa uhlobo olulodwa lokuthweswa iziqu; lapho ukhetha ama-aggregates, ukuze uvimbele ukuvela kwezinhlobo ze-pin-flake, sebenzisa i-cubic shape ukuze uqinisekise ukushumeka okugcwele kwe-aggregates ku-asphalt.
(2) Itiyela. Ukukhethwa kwetiyela kufanele kuqala kuhlangabezane nezidingo ezifanele zokukhethwa kwetiyela ezibekwe umnyango womgwaqo onguthelawayeka. Ngokwesisekelo sokuhlangabezana nokucaciswa, i-emulsified, modified, irabha, noma i-asphalt ye-petroleum evamile ingakhethwa.
(3) Ukusetshenziswa kwezinto ezibonakalayo. Uma usebenzisa ubuchwepheshe bokufaka uphawu lwamatshe ukuze kulungiswe umgwaqo, amatshe adinga ukuhlanganiswa ngokuqinile, futhi itshe kufanele limbozwe ngokugcwele nge-asphalt ukuze limelane nokuguga nokudilika emgwaqeni ngamasondo. Uma inani lokusabalalisa seliningi kakhulu, i-asphalt binder izokhishwa ezikhaleni zamatshe lapho imoto igingqika phezu komgwaqo, futhi indawo yamafutha izovela, ngaleyo ndlela kuncishiswe inkomba yokulwa ne-skid kanye ne-friction yomgwaqo; Nokho, Uma inani lokusabalala kwamatshe lilincane kakhulu, amatshe awakwazi ukuboshwa ngokuphumelelayo, futhi amatshe angase aphonswe ngaphandle komgwaqo.
Kafushane, ukusetshenziswa kwe-asphalt ngesikhathi esisodwa ubuchwepheshe bokuvala amatshe kunomphumela obaluleke kakhulu osebenzayo. Akukwazi nje ukuvimbela ngokuphumelelayo ukuqoqwa kwamanzi emgwaqeni, ukuthuthukisa amandla okugunda komgwaqo, kodwa futhi kuthuthukise ngokuphumelelayo ukusebenza komgwaqo ngaphansi kwezimo eziphansi neziphezulu zokushisa. Ukumelana nokuqhekeka okuphezulu kungavikela indawo ye-asphalt ekugugulekeni noma ekuqhekekeni. Lobu buchwepheshe busakaza i-asphalt eguquliwe kanye netshe elithobelayo ngokulinganayo endaweni yomgwaqo ngesikhathi esifanayo ukuze kuqinisekiswe inhlanganisela ephumelelayo phakathi kokubili futhi kuthuthukise ukunamathela namandla phakathi kokubili. Ngaphezu kwalokho, lobu buchwepheshe buyafaneleka, busindisa izinsiza nezindleko, futhi bunamandla angenzeka. Ngesikhathi esifanayo, ngenxa yezidingo eziphezulu zemishini ehlobene, izindleko zabasebenzi ziyancipha kakhulu. Ngakho-ke, le ndlela yobuchwepheshe ingathuthukiswa ukuze kuthuthukiswe ukumelana nokuqhekeka nokusebenza kwe-anti-skid emigwaqweni yetiyela ngangokunokwenzeka.
