Application of Fly Ash Derived Zeolites in Warm-Mix Asphalt Technology.

摘要: In recent years, numerous studies have been carried out on new technologies allowing to reduce of mix asphalt production temperatures. One the possibilities is foam with “water-containing” additives, which include zeolites. So far, mainly synthetic zeolites Linde A structure type, obtained from chemical reagents, and natural clinoptilolite used in WMA technology. this studies, produced fly ashes 4 different types crystalline were analyzed. Zeolite materials characterized by textural parameters thermal analysis. The amount zeolite added was 0, 3, 5, 7 wt % relation weight asphalt. Determination dynamic viscosity performed at two temperatures: 135 160 time intervals. tests for binders: 35/50 100/150 penetration grade. As a conclusion, it found that pastes zeolitic increases increase added. level depends parameters. potential usefulness ash derived process foaming, water contained method its release, has proved.
