沥青胶浆对心墙沥青混凝土粗骨料抗剪性能影响研究

摘要

心墙沥青混凝土中,沥青与填料形成的沥青胶浆具有很强的粘结力,制备沥青混凝土试件过程中,沥青胶浆裹覆在骨料表面,将骨料与骨料牢牢地粘结在一起.该文在最优配合比基础上,进行了无沥青胶浆下的骨料混合料静三轴试验和沥青混凝土静三轴试验.结果表明,沥青胶浆很大程度上提高了心墙沥青混凝土粗骨料的抗剪性能.%In asphalt concrete core wall, asphalt mortar and asphalt filler formed have strong cohesive force.In the preparation of asphalt concrete specimens, asphalt mortar is wrapped on the surface of aggregate, which made aggregate and aggregate firmly bonded together.Based on the optimal mix ratio, static triaxial tests have been conducted both on aggregate mixture without asphalt mortar and asphalt concrete.The result shows, the asphalt mortar greatly improve the shear performance of asphalt concrete core wall of coarse aggregate.
