中文摘要:

针对心墙沥青混凝土中粗骨料的选择问题，本文用天然砾石和破碎砾石作为粗骨料，细骨料均采用天然河砂制备两种沥青混凝土试件。采用室内试验的方法，分别进行沥青混凝土心墙的水稳定性、拉伸、单轴压缩、小梁弯曲、渗透、静三轴试验。结果表明：沥青混凝土用天然砾石做粗骨料仅在抗压、抗弯强度比用破碎骨料低。天然砾石可以作为本次配合比优选的粗骨料。

英文摘要:

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.
