Monga katswiri wopanga Sinoroader, ife kukupatsani permeable msewu mtundu wa emulsified phula, umene ndi waukulu aggregate mu compaction koyamba, kupopera mbewu mankhwalawa emulsion wosanjikiza pambuyo kubalalitsidwa, kupopera mbewu mankhwalawa emulsion, ndi compacting m'njira dongosolo sitepe ndi sitepe. Ndiwoyenera misewu yachiwiri ndi yachiwiri, ndipo itha kugwiritsidwanso ntchito ngati ulalo wosanjikiza wa phula la asphalt kapena maziko.

Chifukwa cha porosity yaikulu ya mtundu wa emulsified asphalt singano yolowera, pamwamba ndi yosavuta kulowa m'munsi, kotero kuti zopangira ndi zosindikizira kapena zosanjikiza ziyenera kuikidwa. Monga kuyika maziko olimba, ngati chosindikizira. Akagwiritsidwa ntchito ngati chingwe cholumikizira, zinthu ndi pamwamba sizingathe kusindikizidwa.
Emulsified asphalt malowedwe amtundu ndiye kusankha komanga munyengo youma ndi yotentha. Ziyenera kukhala mu nyengo yamvula, theka la mwezi kutentha kwapamwamba kusanatsike kuposa 15 ℃, kotero kuti ikhoza kubayidwa kudzera munjira yotseguka yosanjikiza kuti muyendetse kugudubuza, kupangidwa kwathunthu nyengo isanakwane.
Emulsified asphalt permeable aggregate iyenera kusankhidwa pamakona, kufinyidwa mwamphamvu mwala, ndipo miyala ikasweka, malo ophwanyidwa ndi akulu kuposa 40%. Kukula kosiyanasiyana kwa gawo lalikulu la permeability sikuchepera 50% ya mtengo wonse. Palibe pamwamba wosanjikiza wosanjikiza permeable emulsified phula mtundu, kumapeto kwa yomanga, aliyense 1000㎡ msewu pamwamba ayenera kukhala wina 2 ~ 3 kiyubiki metres, akaphatikiza chabwino pambuyo wosanjikiza kusindikiza zakuthupi ndi specifications chimodzimodzi, chithandizo choyambirira.
