研究了沥青加铺层抵抗反射裂缝的能力 .结果表明沥青混合料的材料组成及结构是旧混凝土路面上沥青加铺层抵抗反射裂缝能力的决定因素 .文中还分别讨论了骨料级配、沥青、矿粉、纤维对抗反射裂缝能力的影响 ,为按功能设计沥青混合料奠定了基础 . The results show that the material composition and structure of asphalt mixture is the decisive factor to resist the reflective cracking ability of the asphalt overlay on the old concrete pavement.In the paper, the effects of aggregate gradation, asphalt , Slag, fiber antireflection crack capacity, as functionally designed asphalt mixture laid the foundation.
