In view of the problem of choice of coarse aggregate for core wall of asphalt concrete, the paper used natural gravel and broken gravel as coarse aggregate, and took natural river sand as fine aggregate to prepared two kinds of asphalt concrete specimens.It used the method of indoor test to carry out water stability, stretching, compression, bending trabecular penetration, static triaxial tests of asphalt concrete core wall respectively.The results showed that only the compressive and flexural strength of asphalt concrete made from natural gravel coarse aggregate is lower than that from broken aggregate. Natural gravel can be used as the coarse aggregate of mixture ratio priority choice.
