Investigation of the Coarse Aggregate Texture Property Using an Improved Laplacian Smoothing Algorithm

Abstract: Surface texture is one of the most important morphology properties of coarse aggregates. It has an important effect on the performances of asphalt mixtures, such as the stiffness modulus and high temperature stability. Accurate characterization of the coarse aggregate texture is important for the quality control of coarse aggregates and the design of asphalt mixtures. The two-dimensional (2-D) image analysis method has been used to study the texture property of coarse aggregates in the past two decades. Becaus… Show more

“…of the material and the shape characteristics of the aggregate (e.g., contour shape, angularity, surface texture, etc.) control the uniformity of the coarse aggregate quality [10][11][12]. Based on the study of Wang et al [13], the crystal size of the aggregate parent rock is inversely related to the abrasion value.…”

“…The physical properties of coarse aggregate such as angularity, size and shape of the particles affect the performance of asphalt mixes significantly [16]. The surface texture of coarse aggregate particles has a significant effect on the resilient modulus [17]. Irregular morphology of aggregate causes an increase in resilient modulus of asphalt mix at 25 • C [18].…”
