Okokuqala, incazelo yokuvimbela ukugcinwa kwesakhiwo sokuhamba nge-asphalt ukhonkolo iyethulwa, futhi ucwaningo lwamanje, ukuthuthukiswa kanye nesimo sokusetshenziswa sokugcinwa kokuvimbela ukwakhiwa kwe-asphalt ukhonkolo we-asphalt ekhaya nakwamanye amazwe kufingqiwe. Izindlela zokwakha ezivame ukusetshenziswa zokuvimbela ukugcinwa kwesakhiwo sokuhamba nge-asphalt ukhonkolo ziyethulwa, futhi emva kokwelashwa kanye nezinye izindaba eziyinhloko zokugcinwa kokuvimbela ukwakhiwa kwe-asphalt ukhonkolo we-asphalt kuyahlaziywa futhi kufingqiwe, futhi umkhuba wokuthuthukiswa kwesikhathi esizayo ulindelwe.

Ukugcinwa kokuvimbela
Ukugcinwa kokuvikela kubhekisela endleleni yokulungisa esetshenziswa lapho ukwakheka kwendlela egandayiwe kungakabonakali. Ithuthukisa isimo sokusebenza sesakhiwo se-pavement futhi ibambezele umonakalo we-asphalt pavement ngaphandle kokwandisa umthamo wokuthwala kwesakhiwo. Uma kuqhathaniswa nezindlela zokunakekela zendabuko, ukunakekelwa kokuvimbela kusebenza kakhulu futhi kudinga ukuhlela okunengqondo ukuze kuzuzwe umphumela oyifunayo.
Kusukela ngo-2006, uMnyango Wezokuthutha wangaphambili uye wakhuthaza ukusetshenziswa kokulungiswa kokuvikela ezweni lonke. Kule minyaka eyishumi edlule, izisebenzi zezwe lami ezilungisa umgwaqo onguthelawayeka seziqalile ukwamukela nokusebenzisa ukunakekelwa kokuvikela, futhi nobuchwepheshe bokulungiswa kokuvikela sebukhule ngokwandayo. Ngesikhathi "soHlelo Lweminyaka Eyishumi Nambili", ingxenye yokulungiswa kokuvikela ezinhlelweni zokunakekelwa kwezwe lami inyuke ngamaphesenti amahlanu unyaka ngamunye, futhi yazuza imiphumela emangalisayo yokusebenza komgwaqo. Kodwa-ke, kulesi sigaba, umsebenzi wokuvikela wokuvikela awukakavuthwa, futhi kusenezindawo eziningi okufanele zifundwe. Kuphela ngokuqongelela okuningi kanye nocwaningo lapho ubuchwepheshe bokulondolozwa kokuvikela bukwazi ukuvuthwa futhi buzuze imiphumela engcono yokusebenzisa.
Izindlela eziyinhloko zokugcinwa kokuvimbela
Ekulungisweni kobunjiniyela bomgwaqo wezwe lami, ngokwesilinganiso nobunzima bephrojekthi yokulungisa, iphrojekthi yesondlo ihlukaniswe yaba: ukugcinwa, ukulungiswa okuncane, ukulungiswa okuphakathi, ukulungiswa okukhulu nokulungiswa kabusha, kodwa asikho isigaba esihlukile sokugcinwa kokuvimbela, okuzokwenza kuthinte kakhulu ukuqaliswa kwamaphrojekthi okugcina okuvikela. Ngakho-ke, ekuthuthukisweni kwesondlo esizayo, ukugcinwa kokuvimbela kufanele kufakwe kububanzi besondlo. Njengamanje, izindlela zokwakha ezivame ukusetshenziswa ekhaya nakwamanye amazwe ukuze kugcinwe ukuvimbela ukwakhiwa komgwaqo ukhonkolo we-asphalt zifaka ukubekwa uphawu, ukufakwa uphawu ngodaka oluncane lwe-micro-surfacing, ukuvalwa kwenkungu nokuvalwa kwamatshe okuchotshoziwe.
Ukubeka uphawu ikakhulukazi kuhlanganisa izinhlobo ezimbili: i-grouting kanye ne-grouting. I-Grouting iwukusebenzisa iglu yobunjiniyela ukuze uvalwe ngokuqondile endaweni lapho kuvela khona imifantu phezu komgwaqo. Njengoba imifantu ivalwe ngeglue, ubukhulu bemifantu abukwazi ukuba bukhulu kakhulu. Le ndlela ifaneleka kuphela ezifweni ezinezifo ezithambile kanye nobubanzi obuncane bokuqhekeka. Lapho kulungiswa, i-gel ene-viscoelasticity enhle nokuzinza kokushisa okuphezulu kufanele isetshenziselwe ukuphatha imifantu, futhi imifantu ebonakala idinga ukuphathwa ngesikhathi. Ukuvalwa kubhekisela ekushisiseni ingxenye eyonakele yomgwaqo nokuyisika ivuleke, bese usebenzisa i-sealant ukuze uvale imithungo emiseleni.
Ubuchwepheshe be-slurry sealing micro-surface bubhekisela endleleni yokusabalalisa izinto ezixubile ezakhiwe ngokuxuba ibanga elithile letshe, i-asphalt e-emulsified, amanzi, kanye nokugcwalisa phezu komgwaqo kusetshenziswa i-slurry sealer. Le ndlela ingathuthukisa ngokuphumelelayo ukusebenza komgwaqo womgwaqo, kodwa ayifanele ukwelashwa kwezifo zomgwaqo ezinezifo ezinkulu.
Ubuchwepheshe bokuvalwa kwenkungu busebenzisa i-asphalt spreader ukufafaza itiyela eliguquliwe elingeneka kakhulu endaweni yomgwaqo ukuze kwakheke ungqimba olungangeni emanzini. Isendlalelo esisanda kwakhiwa somgwaqo esingangeni manzi singathuthukisa ukumelana kwamanzi endaweni yomgwaqo futhi sivimbele ngokuphumelelayo umswakama ekuqhubekeni nokulimaza isakhiwo sangaphakathi.
Ubuchwepheshe be-Chip seal busebenzisa isifutho esizenzakalelayo ukuze kufakwe inani elifanele letiyela endaweni yomgwaqo, bese besakaza amatshe osayizi wezinhlayiyana ezithile ku-asphalt, bese ekugcineni kusetshenziswa i-roller yesondo ukuyigingqa ibe yisimo. Indawo yomgwaqo ephathwa ngobuchwepheshe be-chip seal ithuthukise kakhulu ukusebenza kwayo kwe-anti-skid kanye nokumelana namanzi.
