Abstract: The invention involves “a method to structure mineral aggregate gradation by using three control points & two curves”, including the following steps: (1) Three control points are determined according to the property of the mixtures: nominal maximum size of aggregate and its passing rate, nominal minimum size of aggregate and its passing rate, and the discontinuity point between the coarse aggregate and the fine aggregate and its passing rate. (2) The grading curves of the coarse and the fine aggregate are selected respectively with Power function model, Exponential function model and Logarithmic function model. (3) Measure the stamped density and the stamped voids in mineral aggregate, and then choose the grading of the coarse and the fine aggregate on the basis of the project need. The invention can help constitute different gradation curves in line with local materials from different areas and sources.
