摘要:
由轮廓形状、棱角性和表面纹理量化的矿质集料的形态(形状特征)对沥青混合料的性能具有极为明显的影响.为研究粗集料形态对沥青面层抗剪性能的影响,将粗集料形态视为首要因素,定义了基于图像的粗集料形状参数,采用编制的图像处理程序,获取了五组颗粒形状特征不同的粗集料其形状参数,运用单轴贯入试验分析了粗集料形态参数对SAC-16混合料抗剪强度的影响.结果表明,粗集料各种形态参数对混合料抗剪强度都有不同程度的影响,且扁平比对抗剪强度的影响最大,必须控制粗集料中扁平颗粒的含量.
Abstract:
The morphology (shape characteristics) of mineral aggregates quantified by contour shape, angularity and surface texture have a significant influence on the properties of asphalt mixtures. In order to study the influence of coarse aggregate morphology on the shear performance of asphalt surface layer, the coarse aggregate morphology was regarded as the primary factor, the shape parameters of coarse aggregate based on image were defined, and the shape parameters of five groups of coarse aggregates with different particle shape characteristics were obtained by using the prepared image processing procedure, and the influence of coarse aggregate morphological parameters on the shear strength of SAC-16 mixture was analyzed by uniaxial penetration experiment. The results show that various morphological parameters of coarse aggregate have different degrees of influence on the shear strength of the mixture, and the flatness ratio has the greatest influence on the shear strength, and the content of flat particles in the coarse aggregate must be controlled.
