旧混凝土路面上沥青加铺层的抗反射裂缝能力

Reflective Cracking Resistance of Asphalt Overlay on Old Concrete Pavement

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 .

In this paper, the ability of resisting reflective cracking of asphalt overlay is studied. The results show that the ability of asphalt overlay resisting reflective cracking is mainly decided by the composition and structure of asphalt mixture. The effect of gradation, asphalt, miner filler and fiber on the ability of resisting reflective cracking is discussed. This research has laid some foundation for the mixture design according to function.
