- The surface texture of aggregates has an important influence on the amount of aggregate adsorbed asphalt and the adhesion properties between asphalt and aggregates . The purpose of this paper is to select appropriate methods to characterize and measure the surface characteristics of aggregates. To this end, the Contour GT 3D laser profiler was used to measure the surface texture of aggregates, and the aggregate surface texture parameters and the 3D scanning images of 5 kinds of commonly used aggregates in road engineering were obtained. The results show that the contour arithmetic mean deviation Ra and the contour root mean square deviation Rq can be used to describe the surface roughness of aggregates, and the height of the contour unit (Rt) of aggregate texture is about 1.5 m, which belongs to the typical mesostructure.
