| 中文摘要 | 基于数字图像处理技术,通过沥青混合料均匀性指标,对沥青混合料均匀性与动稳定度、低温劈裂强度、冻融劈裂强度、空隙率以及剪切疲劳间相互关系展开研究.研究结果表明,沥青混合料均匀性与路用性能指标的绝对数值间没有直接明显的相关性,而与路用性能指标的变异性有关,均匀性较差的沥青混合料,路用性能指标的变异性较大;均匀性较好的沥青混合料,路用性能指标的变异性稍小.; Based on digital image processing,the relationship between homogeneity and dynamic stability,low-temperature splitting strength,freeze-thaw splitting strength,air void content and shear fatigue performance of asphalt mixture was investigated via the index of asphalt mixture homogeneity.The research results show that a direct and obvious relationship does not exist between homogeneity and the absolute value of the indices of asphalt pavement performance,but exists between homogeneity and the variation of the indices of asphalt pavement performance;the worse asphalt mixture homogeneity is,the more the variation of the indices is;the better asphalt mixture homogeneity is,the less the variation of the indices is. |
