Ibitumen ye-emulsion ye-microsurfacing iyinto ebophezelayo ekwakhiweni kwendawo encane. Isici salo ukuthi idinga ukuhlangabezana nesikhathi sokuxuba netshe kanye nesikhathi sokuvula sethrafikhi ngemva kokuqedwa kokugandaya. Ukuyibeka kalula, ihlangabezana nezinkinga zesikhathi ezimbili. Isikhathi sokuxuba kufanele sanele, futhi ukuvulwa kwethrafikhi kufanele kusheshe, yilokho kuphela.
Ake sikhulume nge-emulsion bitumen futhi. I-Emulsion bitumen i-emulsion yebitumen yamafutha emanzini. Iwuketshezi oluyi-viscous ngokulinganayo ezingeni lokushisa lasekamelweni. Ingasetshenziswa ngokubanda futhi ayidingi ukushisa. Iwonga amandla futhi ayihambisani nemvelo. I-Emulsion bitumen ihlukaniswe yaba izinhlobo ezintathu ngokuya ngama-emulsifiers ahlukene ebitumen asetshenziswa ekukhiqizeni: ukuqhekeka kancane, ukuqhekeka okuphakathi, nokuqhekeka ngokushesha. Itiyela enziwe nge-emulsified esetshenziswa ekwakhiweni kwe-micro-surfacing iqhekeka kancane futhi ibeka ngokushesha itiyela le-cationic emulsion. Lolu hlobo lwebitumen ye-emulsion lulungiswa kusetshenziswa i-bitumen emulsifier yokuqhekeka kancane nokumisa ngokushesha futhi kwengezwe izilungisi ze-polymer. Ingakwazi ukufeza isikhathi esanele sokuxuba kanye nomphumela wokusetha okusheshayo. Ukunamathela phakathi kwama-cations namatshe kuhle, ngakho-ke uhlobo lwe-cationic luyakhethwa.

I-emulsion bitumen eqhekeka kancane futhi esheshayo isetshenziselwa ikakhulukazi ukulungiswa komgwaqo okuvimbelayo. Okusho ukuthi, isetshenziswa lapho isendlalelo sesisekelo siqinile kodwa isendlalelo esingaphezulu sonakalisiwe, njengokuthi indawo yomgwaqo ibushelelezi, iqhekekile, igugile, njll.
Indlela yokwakha: Fafaza ungqimba lwamafutha anamathelayo kuqala, bese usebenzisa i-micro-surfacing/slurry seal paver ukuganda. Lapho indawo iyingcosana, kungasetshenziswa ukuxutshwa ngesandla nokugandaywa kwe-emulsion bitumen netshe. Ukulinganisa kuyadingeka ngemva kokugandaywa. Ingasetshenziswa ngokujwayelekile ngemva kokulinda ukuthi ubuso bome. Kusebenza ku: ukwakhiwa kongqimba oluncane phakathi kuka-1 cm. Uma ubukhulu budinga ukudlula u-1 cm, kufanele bugandaywe ngezingqimba. Ngemva kokuba ungqimba olulodwa lomile, ungqimba olulandelayo lungagandaywa. Uma kunezinkinga ngesikhathi sokwakhiwa, ungaxhumana nenkonzo yamakhasimende ukuze ubonisane!
Ibitumen ye-emulsion enensayo futhi esheshayo iwukwenza usimende ukuvala uphawu oludaka kanye nokugandaywa kwe-micro-surface. Ukukhuluma ngokuqinile, ekwakhiweni kwe-slurry seal eguquliwe kanye ne-micro-surfacing, i-emulsion bitumen eqhekeka kancane futhi ebeka ngokushesha idinga ukungezwa nge-modifier, okungukuthi, i-emulsion bitumen eguquliwe.
