Izinto zikasimende ezisetshenziswa ekubekweni phansi okuncane yibitumen eguquliwe. Yiziphi izici zayo? Ake sikhulume ngendlela yokwakha ye-microsurfacing kuqala. I-Micro Surfacing isebenzisa i-paver encane eyenza ukusabalalisa ngokulinganayo ibanga elithile letshe, isigcwalisi (usimende, umcako, njll.), itiyela elifakwe emulsified, amanzi nezinye izithasiselo phezu komgwaqo ngokulingana. Le ndlela yokwakha inezinzuzo ezithile ngoba impahla yokubopha esetshenziswayo ishintshwa itiyela elenziwe ngokunensa elisetha ngokushesha.
I-micro-surface inezinto ezingcono zokulwa nokugqoka kanye ne-anti-slip. Uma kuqhathaniswa nama-slurry sealant ajwayelekile, ingaphezulu le-micro-surface linokwakheka okuthile, okungamelana nokushwibilika kwezimoto kanye nokushelela futhi kuqinisekise ukuphepha kokushayela. Isisekelo saleli phuzu siwukuthi usimende osetshenziswa ekufakweni kwe-micro-surfacing kufanele ube nezakhiwo ezinhle zokubopha.
Ngemva kokwengeza ama-modifiers ku-bitumen e-emulsified evamile, izakhiwo zebitumen ziyathuthukiswa, futhi ukusebenza okuhlangene kwe-micro-surface kuyathuthukiswa. Lokhu kwenza umgwaqo ngemva kokwakhiwa ube nokuqina okungcono. Ukusebenza okuthuthukisiwe kwezinga lokushisa eliphezulu neliphansi lokugandaywa kwezinyawo.
Esinye isici esibalulekile sebitumen e-emulsified eguquliwe eshintshwayo enyakaziswa kancane futhi esheshayo esetshenziswa ekwakhiweni kwe-micro-surface ukuthi ingakhiwa ngomshini noma ngesandla. Ngenxa yezimpawu zayo ze-demulsification ezihamba kancane, ihlangabezana nezidingo zokuxuba zengxube. Lokhu kwenza ukwakhiwa kuguquguquke, futhi indlela yokwakhiwa efanele ingakhethwa ngokuvumelana nesimo sangempela, okuvumela uhlelo lokudweba ngesandla ukuba lufezeke.
Ngaphezu kwalokho, izinto zikasimende endaweni encane nazo zinesici sokusetha okusheshayo. Lesi sici sivumela indawo yomgwaqo ukuthi ivulekele ithrafikhi amahora angu-1-2 ngemva kokwakhiwa, ukunciphisa umthelela wokwakhiwa kuthrafikhi.
Elinye iphuzu liwukuthi izinto zokubopha ezisetshenziselwa ukwakhiwa kwe-micro-surfacing ziwuketshezi ekamelweni lokushisa futhi akudingi ukushisa, ngakho-ke ukwakhiwa okubandayo. Lokhu akugcini nje ukuthuthukisa ukusebenza kahle kokwakhiwa, kodwa futhi kunciphisa ukusetshenziswa kwamandla, okuhambisana nomqondo wokongiwa kwamandla nokuvikelwa kwemvelo. Uma kuqhathaniswa nokwakhiwa kwebitumen eshisayo yendabuko, indlela yokwakha ebandayo ye-micro-surfacing ayikhiqizi amagesi ayingozi futhi inomthelela omncane emvelweni kanye nabasebenzi bokwakha.
Lezi zici ziyizimfuneko zokuqinisekisa umphumela wokwakha futhi ziyizici ezidingekayo. Ingabe i-bitumen efakwe emulsified oyithengile inazo lezi zakhiwo?
