A New Solidification Technology Of Municipal Solid Waste Incineration Fly Ash And Its Application In Asphalt Mixture

Fly ash is consolidated by cement and the new consolidation agent, and the two kinds of cube samples(40x40x40mm) used to consolidate the fly ash are made though the methods mentioned above; Comparing the strength of the samples for test resistance strength and flexural strength test after standard curing. The consolidation effect of the new curing agent for the metal ions in fly ash is better than that of cement, through the test of the heavy metal consolidation rate with different consolidation agent. By comparison with experimental data, it is concluded that the best substitution amount of fly ash is 75% in asphalt mixture. As well as testing physical and mechanical performance of specimens added optimum amount of fly ash, shows that the physical and mechanical properties of asphalt mixture with the new consolidation technology is better than that of ordinary asphalt mixture, and fly ash can be used as a filler in production of asphalt mixture.
