Mipando ya phula imakhala yolimba komanso yosinthasintha kuposa mayendedwe a simenti, ndipo chitonthozo choyendetsa galimoto ndichapamwamba kuposa miyala ya simenti. M'zaka zaposachedwapa, phula la asphalt lakhala likugwiritsidwa ntchito kwambiri. Asphalt ndi chinthu chodziwika bwino chapamsewu. Asphalt ndi miyala ina yosakanizidwa imasakanizidwa pamalo osakaniza a asphalt kuti apange chisakanizo cha phula, chomwe chimayikidwa pamsewu ndikugudubuza. Iyi ndi njira yodziwika bwino yogwiritsira ntchito. Phula likhoza kupangidwanso kukhala phula lopangidwa ndi emulsified ndi kupopera pakati pa zigawo za phula lotentha losakaniza kuti likhale ngati wothandizira komanso woletsa madzi. Ndiye kodi emulsified asphalt ndi chiyani?
Emulsified asphalt amapangidwa potenthetsa njira yamadzi ya phula ndi emulsifier kudzera pazida zopangira phula. Emulsified asphalt ndi madzi ofiirira pansi pamikhalidwe yabwinobwino. Ndi madzi otentha ndipo ndi osavuta kusunga. Njira yomanga ndi yosavuta ndipo palibe kutentha kapena kuipitsa panthawi yomanga. Emulsified asphalt, yomwe imadziwikanso kuti phula lamadzi, ndi mtundu wa asphalt wamadzimadzi.
Mu engineering ya asphalt pavement, emulsified asphalt angagwiritsidwe ntchito m'misewu yatsopano ndi kukonza misewu. Panjira yomwe yangomangidwa kumene makamaka imakhala yosanjikiza yolowera, zomatira ndi slurry seal layer. Pankhani yokonza misewu, mwachitsanzo: fog seal, slurry seal, modified slurry seal, micro surfacing, fine sufacing, etc.
Pankhani ya emulsified asphalt, pali zolemba zambiri zokhudzana ndi nkhani zam'mbuyomu, mutha kulozera kwa iwo. Ngati mukufuna kuyitanitsa, mutha kulumikizana ndi kasitomala watsambalo! Zikomo chifukwa cha chidwi chanu ndi thandizo lanu ku Tantulu Road ndi Bridge!
