It is not yet clear that the filler plays any part in the asphalt pavement. But being generally believed to have a large effect upon the stability and durability of pavement, the study of filler is very important. Up to this time, the stone dust has usually been used as filler, but in this experiment the flyash is adopted instead of it. The reason is that the price of stone dust is higher than that of flyash. The main object of this experiment is to make sure that the flyash is able to be used as filler or not. According to this experiment, in case of asphalt concrete, the stability of asphalt mixture added the flyash is higher than that of the stone dust adding asphalt mixture. But in other mixtures, such as topeka and sheet asphalt, the former shows lower stability than the latter. In order to improve this fault of flyash, some additives are used at the next experiment. And the result obtained is reported in this paper.
