Ukuze kufakwe i-microsurfacing, isilinganiso ngasinye semiksi esithuthukisiwe siwukuhlola kokuhambisana, okuthintwa okuguquguqukayo okuningi okufana netiyela elifakwe emulsified kanye nohlobo lwe-aggregate, ukuhlukaniswa okuhlanganisiwe, amanzi kanye namanani etiyela afakwe emulsified, kanye nezinhlobo zokugcwalisa amaminerali nezithasiselo. . Ngakho-ke, ukuhlaziywa kokuhlolwa kokulingisa endaweni kwamasampula aselabhorethri ngaphansi kwezimo ezithile zobunjiniyela kube ukhiye wokuhlola ukusebenza kwezingxube ze-micro-surface. Ukuhlolwa okuningana okuvame ukusetshenziswa kwethulwa ngale ndlela elandelayo:
1. Ukuhlolwa kokuxuba
Inhloso eyinhloko yokuhlolwa kokuxutshwa ukulingisa indawo yokwakha egandayiwe. Ukuhambisana kwe-asphalt e-emulsified kanye nama-aggregates kuqinisekiswa ngesimo sokubumba se-micro-surface, futhi kutholakala isikhathi sokuxuba esiqondile nesinembile. Uma isikhathi sokuxuba siside kakhulu, indawo yomgwaqo ngeke ifinyelele amandla okuqala futhi ngeke ivulekele ithrafikhi; uma isikhathi sokuxuba sisifushane kakhulu, ukwakhiwa kwe-paving ngeke kube bushelelezi. Umphumela wokwakhiwa kwe-micro-surfacing uthinteka kalula emvelweni. Ngakho-ke, lapho uklama ukuxuba, isikhathi sokuxuba kufanele sihlolwe ngaphansi kwamazinga okushisa amabi angase avele ngesikhathi sokwakhiwa. Ngochungechunge lokuhlolwa kokusebenza, izici ezithinta ukusebenza kwengxube ye-micro-surface zihlaziywa ngokuphelele. Iziphetho ezifinyelelwe zimi kanje: 1. Izinga lokushisa, indawo yokushisa ephezulu inganciphisa kakhulu isikhathi sokuxuba; 2. I-Emulsifier, umthamo omkhulu we-emulsifier, isikhathi sokuxuba siba side; 3. Usimende, ukwengeza usimende kungase kunwebe noma kunciphise ingxube. Isikhathi sokuxuba sinqunywa izici ze-emulsifier. Ngokuvamile, inani elikhulu, isikhathi sokuxuba siba sifushane. 4. Inani lamanzi okuxuba, amanzi amaningi okuxuba, isikhathi sokuxuba siba side. 5. Inani le-pH lesisombululo sensipho ngokuvamile liyi-4-5 futhi isikhathi sokuxuba side. 6. Amandla amakhulu we-zeta we-asphalt e-emulsified kanye nesakhiwo sesendlalelo sikagesi esiphindwe kabili se-emulsifier, isikhathi sokuxuba siba side.
2. Ukuhlolwa kokunamathela
Ihlola kakhulu amandla okuqala endawo encane, engakala ngokunembile isikhathi sokuqala sokusetha. Amandla anele angaphambi kwesikhathi imfuneko yokuqinisekisa isikhathi sokuvula kuthrafikhi. Inkomba yokunamathela idinga ukuhlolwa ngokucophelela, futhi inani lokunamathela elilinganisiwe kufanele lihlanganiswe nesimo somonakalo wesampula ukuze kunqunywe isikhathi sokuqala sokusetha kanye nesikhathi esivulekile sethrafikhi yengxube.
3. Ukuhlolwa kokugqokwa kwamasondo okumanzi
Ukuhlolwa kokuhuzuka kwesondo elimanzi kulingisa ikhono lomgwaqo lokumelana nokuguga kwamasondo uma limanzi.
Ukuhlolwa kokuhuzuka kwesondo elimanzi kwehora elilodwa kunganquma ukumelana nokuhuzuka kongqimba olusebenzayo lwe-microsurface kanye nezakhiwo zokumboza zetiyela nokuhlanganisa. Ukumelana nomonakalo wamanzi wengxube ye-asphalt eshintshiwe ye-micro-surface modified emulsified imelelwa inani lokugqoka lezinsuku ezingu-6, futhi ukuguguleka kwamanzi kwengxube kuhlolwa ngenqubo ende yokucwiliswa emanzini. Kodwa-ke, umonakalo wamanzi awubonakali nje kuphela ekushintsheni ulwelwesi lwe-asphalt, kodwa futhi ukuguqulwa kwesimo sesigaba samanzi kungabangela umonakalo kumxube. Ukuhlolwa kokucwiliswa kokucwiliswa kwezinsuku eziyi-6 akuzange kucabangele umthelela womjikelezo wokuqandisa wamanzi kutshe lensimbi ezindaweni ezibandayo zesizini. Ukunyuka kwesithwathwa nokuxebuka okubangelwa ifilimu ye-asphalt ebusweni bento. Ngakho-ke, ngokusekelwe ocwaningweni lwezinsuku eziyisi-6 lokucwiliswa emanzini okuhuzuka kwamasondo amanzi, kuhlelwe ukuthi kusetshenziswe ukuhlolwa kokuhuzuka komjikelezo wokuncibilika emanzini ukuze kubonakale ngokugcwele imiphumela emibi yamanzi engxubeni ye-micro-surface.
4. Rutting deformation test
Ngokuhlolwa kokuguqulwa kwe-rutting, izinga lokuguquguquka kobubanzi bethrekhi yesondo lingatholwa, kanye nekhono lokulwa ne-rutting lengxube ye-micro-surface lingahlolwa. Uma kuncane izinga lokuguquguquka kobubanzi, amandla okumelana ne-rutting deformation kanye nokuba ngcono kwezinga lokushisa eliphezulu; ngokuphambene, ikhono elibi kakhulu lokumelana nokuguga ukuguga. Ucwaningo luthole ukuthi izinga lokuguquguquka kobubanzi bethrekhi yesondo linokuxhumana okucacile nokuqukethwe kwe-asphalt e-emulsified. Uma kukhulu okuqukethwe kwe-asphalt e-emulsified, kuba kubi nakakhulu ukumelana ne-rutting yengxube ye-micro-surface. Uveze ukuthi lokhu kungenxa yokuthi ngemuva kokuthi i-asphalt ye-polymer emulsified ifakwe kusimende esisekelwe ku-inorganic binder, i-elastic modulus ye-polymer iphansi kakhulu kunekasimende. Ngemva kokusabela okuhlanganisiwe, izakhiwo ze-cementitious material ziyashintsha, okuholela ekunciphiseni kokuqina okuphelele. Ngenxa yalokho, i-wheel track deformation iyanda. Ukwengeza kulezi zivivinyo ezingenhla, izimo zokuhlola ezihlukene kufanele zisethwe ngokuya ngezimo ezihlukene futhi kufanele kusetshenziswe ukuhlolwa kwesilinganiso sokuxutshwa okuhlukile. Ekwakhiweni kwangempela, isilinganiso sokuxuba, ikakhulukazi ukusetshenziswa kwamanzi kwengxube kanye nokusetshenziswa kukasimende, kungalungiswa ngokufanele ngokuvumelana nesimo sezulu esihlukile namazinga okushisa.
Isiphetho: Njengobuchwepheshe bokulondolozwa kokuvikela, i-micro-surfacing ingathuthukisa kakhulu ukusebenza okuphelele kwe-pavement futhi iqede ngempumelelo umthelela wezifo ezahlukahlukene endaweni egandayiwe. Ngesikhathi esifanayo, inezindleko eziphansi, isikhathi esifushane sokwakha kanye nomphumela omuhle wokulungisa. Lesi sihloko sibuyekeza ukwakheka kwezingxube ze-micro-surfacing, ihlaziya umthelela wazo kukho konke, futhi yethula kafushane futhi ifinyeze izivivinyo zokusebenza kwezingxube ezingaphansi komhlaba ezincanyana ezicacisweni zamanje, ezinokubaluleka okuhle kwesithenjwa socwaningo olujulile lwesikhathi esizayo.
Nakuba ubuchwepheshe be-micro-surfacing sebukhule ngokwandayo, kusafanele bucwaningwe futhi buthuthukiswe ukuze kuthuthukiswe izinga lobuchwepheshe ukuze kuthuthukiswe kangcono futhi kuthuthukiswe ukusebenza okuphelele kwemigwaqo emikhulu futhi kuhlangatshezwane nezidingo zokusebenza kwethrafikhi. Ngaphezu kwalokho, ngesikhathi senqubo yokwakha i-micro-surfacing, izimo eziningi zangaphandle zinomthelela oqondile kwikhwalithi yephrojekthi. Ngakho-ke, izimo zangempela zokwakha kufanele zicatshangelwe futhi kukhethwe izindlela zokulondoloza ezesayensi ezengeziwe ukuze kuqinisekiswe ukuthi ukwakhiwa kwe-micro-surfacing kungenziwa ngokushelela futhi kuzuzwe Ukwenza ngcono umphumela wokulungisa.
