Evaluation of Particle Size Distribution of Aggregates in Asphalt Concrete by Means of Image Analysis Software

Analysis of (cylindrical) samples of asphalt concrete, in terms of weight and size distribution of different fractions of aggregates and by means of mechanical methods is a complicated and time consuming process. This article presents a proposal of a method for the same kind of analysis, but without the need for machining. The suggested method is based solely on a computer based analysis of photographs of the samples. The mechanism described in this paper is only a preliminary process, illustrating the potential use of an image analysis for this type of study.
