摘要
基于数字图像处理技术,简述了沥青混合料均匀性的评价方法,并对广梧高速公路长寿命沥青混凝土路面试验段的均匀性进行了定量研究.研究结果表明:试验路段中下面层SAC-20I的均匀性相对较好;上面层SMA-13要比其他非试验段上面层AK-13的均匀性要好.
On the basis of digital image processing, a method for evaluating homogeneity of asphalt mixtures is introduced compendiously and homogeneity of the perpetual asphalt concrete pavement on the test section of Guany-Wu Expressway is studied quantitatively in this paper. The study results reveal that the homogeneity of SAC-20I of the test section is better comparatively; the homogeneity of SMA-13 is better than that of non-test sections.
