An image-based gradation calculation method considering crushed stone morphology is proposed in here this paper.Eight kinds of crushed stones are prepared to figure out the effect of the particle shape on the gradation.All particles are pictured, and the photos are processed to obtain particle shape indices by using the image-based method.A minimum
