| Abstract: | As a kind of semi-rigid base material, cement-fly-ash stabilized crushed-stones aggregate mixture gets a extensive application in several regions of China, however, cracking is its drawback. On the base of new grading scope, by the experiment of Anti-brushing performance, Anti-fatigue performance, freezing and thawing resistance, this paper provide a best ratio of cement and fly-ash. |
