Phula la emulsified lomwe limapangidwa ndi zida zosakaniza za asphalt ndizovuta kwambiri, koma mvula imapezeka panthawi yosungira. Kodi izi ndizabwinobwino? Kodi chodabwitsachi chimayambitsa chiyani?
M'malo mwake, ndizabwinobwino kuti asphalt iwonjezeke panthawi yomwe ilipo, ndipo samathandizidwa malinga ngati zofunikira zikukwaniritsidwa. Komabe, ngati sichikukwaniritsa zofunikira zogwiritsira ntchito, ikhoza kuthandizidwa ndi njira monga kulekanitsa madzi ndi mafuta. Chifukwa chomwe asphalt imakwera chifukwa kachulukidwe kamadzi kamakhala kakang'ono, kumayambitsa kusanja.

Chifukwa chake pali mafuta otsetsereka pamtunda wa phula ndi chifukwa pali thovu zambiri zomwe zimapangidwa panthawi ya emulsification. Mithovu ikaphulika, imakhalabe pamwamba, kupanga mafuta opendekera. Ngati pamwamba pa mafuta oyandama sali wandiweyani kwambiri, sonkhezerani musanagwiritse ntchito kuti musungunuke. Ngati itatha, muyenera kuwonjezera chinthu choyenera chochotsera thovu kapena kusonkhezera pang'onopang'ono kuti muchotse.
