1. Ukulungiselela ukwakhiwa
Okokuqala, ukuhlolwa kwezinto ezingavuthiwe kufanele kuhlangabezane nezidingo ezijwayelekile zobuchwepheshe. Imitha, ukuxuba, ukuhamba, ukugandaya kanye nezinhlelo zokuhlanza zomshini wokuvala uphawu oludaka kufanele kuvinjelwe, kulungiswe iphutha futhi kulinganiswe. Okwesibili, izindawo ezinezifo zendlela yokwakha kumele ziphenywe kahle futhi kubhekwane nazo kusenesikhathi ukuze kuqinisekiswe ukuthi umgwaqo wokuqala ubushelelezi futhi uphelele. Imizila, imigodi, nemifantu kufanele kumbiwe futhi kugcwaliswe ngaphambi kokwakhiwa.
2. Ukuphathwa kwethrafikhi
Ukuze kuqinisekiswe ukuhamba okuphephile nokubushelelezi kwezimoto nokusebenza kahle kokwakhiwa. Ngaphambi kokwakhiwa, kuyadingeka ukuthi uqale uxoxisane neminyango yendawo yokulawulwa kwethrafikhi kanye nemithetho yomthetho mayelana nolwazi lokuvalwa kwethrafikhi, umise izimpawu zokwakhiwa nokuphepha komgwaqo, futhi unikeze izisebenzi zokulawula umgwaqo ukuphatha ukwakhiwa ukuze kuqinisekiswe ukuphepha kokwakhiwa.
3. Ukuhlanzwa komgwaqo
Lapho kwenziwa ukwelashwa kwe-micro-surfacing emgwaqeni onguthelawayeka, indawo yomgwaqo onguthelawayeka kufanele iqale ihlanzwe kahle, futhi umgwaqo ongelula ukuwuhlanza kufanele ugezwe ngamanzi, futhi ukwakhiwa kungenziwa kuphela ngemva kokuba somile ngokuphelele.
4. Ukukhipha nokumaka imigqa
Ngesikhathi sokwakhiwa, ububanzi obugcwele bomgwaqo kufanele bulinganiswe ngokunembile ukuze kulungiswe ububanzi bebhokisi lokugandaya. Ukwengeza, izinombolo eziningi ngesikhathi sokwakha zingama-integers, ngakho imigqa yomhlahlandlela yokumaka amakhondaktha nemishini yokuvala kufanele ihambisane nemigqa yomngcele wokwakha. Uma kukhona imigqa yolayini yasekuqaleni endaweni yomgwaqo, ingasetshenziswa futhi njengezinkomba ezisizayo.
5. Ukugandaywa kwendawo encane
Shayela umshini wokufaka uphawu we-slurry oshintshiwe kanye nomshini wokuvala olayishwe ngezinto ezihlukahlukene zokusetshenziswa endaweni yokwakha, bese ubeka umshini endaweni efanele. Ngemva kokuba ibhokisi lokugandaya selilungisiwe, kufanele lihambisane nokujika nobubanzi bomgwaqo ogandayiwe. Ngesikhathi esifanayo, kuyadingeka ukuyihlela ngokwezinyathelo zokulungisa ubukhulu bomgwaqo ogandayiwe. Okwesibili, vula ukushintshwa kwezinto bese uvumela ukuthi izinto zixutshwe ebhodweni lokuxuba ukuze i-aggregate, amanzi, i-emulsion ne-filler ngaphakathi kuhlanganiswe kahle ngokulingana okulinganayo. Ngemva kokuxuba kahle, uthele ebhokisini lokugandaya. Ukwengeza, kuyadingeka ukubheka ukuhambisana kokuxuba kwengxube futhi ulungise umthamo wamanzi ukuze i-slurry ikwazi ukuhlangabezana nezidingo zomgwaqo ngokuhambisana nokuxuba. Futhi, lapho ivolumu yokuvula ifinyelela ku-2/3 we-slurry exutshwe, vula inkinobho ye-paver futhi uqhubekele phambili emgwaqeni omkhulu ngesivinini esingaguquki samakhilomitha angu-1.5 kuya kwangu-3 ngehora. Kodwa gcina ivolumu yokusabalalisa i-slurry ihambisana nevolumu yokukhiqiza. Ukwengeza, umthamo wengxube ebhokisini lokugandaya kufanele ube ngu-1/2 ngesikhathi somsebenzi. Uma izinga lokushisa lomgwaqo liphezulu kakhulu noma umgwaqo womile ngesikhathi somsebenzi, ungavula futhi isifafaza ukuze umanzise umgwaqo.
Lapho enye yezinto ezisele emshinini wokuvala isetshenziswa, inkinobho yokusebenza okuzenzakalelayo kufanele ivalwe ngokushesha. Ngemuva kokuthi yonke ingxube ebhodweni lokuxuba isakazwa, umshini wokufaka uphawu kufanele umise ngokushesha ukuya phambili futhi uphakamise ibhokisi lokugandaya. , bese ukhipha umshini wokuvala endaweni yokwakha, ugeze izinto ezisebhokisini ngamanzi ahlanzekile, futhi uqhubeke nomsebenzi wokulayisha.
6. Gcoba
Ngemuva kokuthi umgwaqo ugandaywe, kufanele ugoqwe nge-pulley roller ephula i-asphalt emulsification. Ngokuvamile, ingaqala imizuzu engamashumi amathathu ngemva kokugandaywa. Inani lokudlula okugoqayo licishe libe ngu-2 kuya ku-3. Ngesikhathi sokugoqa, into eqinile yethambo le-radial ingakhanywa ngokuphelele endaweni esanda kugandaywa, ithuthukise ingaphezulu futhi iyenze iminyene futhi ibe yinhle. Ngaphezu kwalokho, ezinye izesekeli ezixekethile kufanele futhi zihlanzwe.
7.Isondlo sokuqala
Ngemuva kokuthi ukwakhiwa kwe-micro-surface kwenziwa emgwaqeni onguthelawayeka, inqubo yokwakheka kwe-emulsification esendlalelo sokuvala kufanele igcine umgwaqo omkhulu uvaliwe kuthrafikhi futhi ivimbele ukudlula kwezimoto nabahamba ngezinyawo.
8Vula kuthrafikhi
Ngemva kokuphothulwa kokwakhiwa komgwaqo onguthelawayeka, zonke izimpawu zokulawula izimoto kufanele zisuswe ukuze kuvulwe umgwaqo, kungashiyi izithiyo ukuze kuqinisekiswe ukuhamba kahle komgwaqo omkhulu.
