集料是沥青混凝土、水硬性水泥混凝土和粒料基层的重要组成部分。集料的形状、棱角性和表面纹理基本上是不同尺寸尺度下粗糙程度的变化，并以不同方式影响混合料的性能。本文提出了一种统一的傅里叶形态分析方法来量化集料的形状、棱角性和表面纹理。对10种已知质量的集料的这些特性进行评估表明，傅里叶形态分析对这些集料的定量排序与定性评估结果一致。
Aggregates are an important constituent of asphalt concrete, hydraulic cement concrete, and granular base. The shape, angularity, and surface texture of aggregates are basically variations of asperities at different dimensional scales and affect mixture properties in different ways. This paper presents a unified Fourier morphological analysis method to quantify the shape, angularity, and surface texture of aggregates. Evaluation of these characteristics of 10 aggregates of known quality indicates that Fourier morphological analysis quantitatively ranks these aggregates in consistence with qualitative evaluations.
