In order to explore the effect of natural gravel and artificial crushed rock as coarse aggregate on the performance of core wall asphalt concrete,under the same basic mix ratio,the paper used two kinds of mineral materials to confect asphalt concrete,and conducted the marshall stability, small beam bending and static three axis test.The results show that the anti deformation ability of natural gravel aggregate is better than that of artificial broken rock, the difference of mechanical properties of the two matericals is not obvious. Therefore, the natural gravel aggregate can be directly used in the core wall asphalt concrete.
