【摘要】 普通的沥青在使用过程中容易受到很多破坏,因此要加入改性剂来增加沥青的粘附性,提高稳定性和抗压强度,使得流值变小.这些改性剂呈星点状分散在沥青中,而颗粒的大小和分布将直接影响改性剂在沥青中发挥其性能.根据改性剂颗粒在沥青图像中的灰度特性及几何特征,提出了一种简单、实用、有效的显微镜下沥青图像中改性剂颗粒的识别方法.更多还原

【Abstract】 General asphaltum could be easily broken when it is used,so some alter-quality solvent is added to increase it′s conglutination , stabilization and renitency strength.This alter-quality solvents presents starlike in asphaltum,and its size and distribution will influence capability.This paper presents a kind of method to identify the image according to the characteristics of gray and geometry.更多还原
