Ngokuthuthuka okusheshayo komnotho wezwe lethu kanye nobuchwepheshe, izimo zemigwaqo yezwe lethu zibe ngcono kakhulu. Nokho, umthamo womthwalo wezimoto nawo ukhula ngokushesha, futhi nenani lamaloli amakhulu liyanda, okulethe ingcindezi enkulu kwezokuthutha. Ngakho-ke, umgwaqo onguthelawayeka Umsebenzi wokulungisa uye wadonsa amehlo abantu kancane kancane.
Imigwaqo egandayiwe yemigwaqo emikhulu yendabuko isebenzisa izinto ezijwayelekile zokuhlanganisa itiyela, okukude kakhulu nokuhlangabezana nezindinganiso eziphakeme kanye nezidingo zezokuthutha zesimanje zemigwaqo emikhulu. Indlela yokulungisa i-asphalt yebanga eliphezulu yokuhlanganisa i-asphalt ukuze kuqinisekiswe ikhwalithi nokusebenza kahle kokusetshenziswa komgwaqo onguthelawayeka kuwumbuzo okufanele uhlolisiswe. Ukuvalwa kwe-slurry sealing kanye nobuchwepheshe be-micro-surfacing buthuthukiswa kancane kancane njengezindlela zokuvikela zokuvikela ezinekhwalithi enhle kanye nezindleko zokonga.
Ukwakhiwa kwengxube ye-asphalt slurry emulsified kuyinkimbinkimbi, ikakhulukazi kufaka phakathi usimende, umlotha wempukane, i-mineral powder kanye nezithasiselo. Ingxube ye-slurry isebenzisa itshe noma isihlabathi njengenhlanganisela eyisisekelo, kodwa ukukhethwa kwetshe nesihlabathi akunangqondo, kodwa kufanele kufinyelele ukuhlelwa okuthile, bese wengeza ingxenye ethile ye-asphalt e-emulsified njengento ebophayo ukuze kuzuzwe umphumela obophayo. Uma isimo sikhethekile, ungase futhi ukhethe ingxenye ethile ye-powder. Ngemuva kokuthi zonke izithako zengezwe, zixutshwe namanzi ngesilinganiso esithile ukuze zenze ingxube ye-asphalt. Ingxube ye-asphalt eyenziwe yilezi zingxenye iwuketshezi futhi kulula ukuyisebenzisa ngesikhathi sokulungiswa komgwaqo. Ingxube ifafazwa phezu komgwaqo ngeloli elivala udaka ukuze kwakheke isivalo se-slurry. Amaphuzu ayinhloko wezobuchwepheshe wokufafaza aqhubekayo futhi afanayo. Ingxube yenza ungqimba oluncane lokwelashwa kwe-asphalt ebusweni bomgwaqo, okuzuzisa inqubo elandelayo. Umsebenzi oyinhloko walolu ungqimba oluncane ukuvikela indawo yokuqala yomgwaqo nokunciphisa ukuguga komgwaqo.
Ngenxa yokufakwa kwengxenye ethile yamanzi engxubeni yokuvalwa kwe-slurry, kulula ukuhwamuka emoyeni. Ngemva kokuba amanzi ehwamukile, ayokoma futhi abe lukhuni. Ngakho-ke, ngemva kokwakhiwa kwe-slurry, akubukeki nje kufana kakhulu nekhonkrithi ye-asphalt enezinhlamvu ezinhle, kodwa akuphazamisi ukubukeka komgwaqo. Iphinde ibe nezici zobuchwepheshe ezifanayo njengokhonkolo owenziwe kahle mayelana nokumelana nokugqokwa, i-anti-skid, ukuvimbela amanzi, kanye nokushelela. Ubuchwepheshe be-slurry seal busetshenziswa ekulungisweni komgwaqo omkhulu ngenxa yobuchwepheshe bayo obulula bokwakha, isikhathi sokwakha esifushane, izindleko eziphansi, ikhwalithi ephezulu, ukusetshenziswa okubanzi, ukuguquguquka okuqinile, njll. Kuyindlela eyongayo nephumelelayo. Ubuchwepheshe bokulungisa umgwaqo we-asphalt bufanele ukusetshenziswa nokukhuthazwa. Ngaphezu kwalokho, izinzuzo zalobu buchwepheshe nazo zibonakala ngamandla amakhulu okubopha phakathi kwe-asphalt nezinto zamaminerali, inhlanganisela eqinile nomgwaqo womgwaqo, ikhono lokumboza ngokuphelele izinto zamaminerali, amandla aphezulu kanye nokuqina okuhle.
