Asphalt mixture aggregate supply optimization system and aggregate supply optimization method

摘要

PROBLEM TO BE SOLVED: To provide an aggregate supply optimization system for an asphalt mixture capable of rapidly acquiring measured value data regarding the particle size of the aggregate of the asphalt mixture and easily stabilizing the quality of the asphalt mixture using the measured value data. It is to provide a method for optimizing the amount of aggregate supplied. SOLUTION: An aggregate supply amount optimization system 80 performs an image analysis process on new aggregate A image data and measures a new pre-mixed aggregate particle size Hkj for each storage bin 15a to 15e. A first arithmetic apparatus including a processing apparatus 83, a first arithmetic apparatus 86a for calculating the total aggregate particle size Yj of the asphalt mixture based on the new aggregate particle size Hkj before mixing and the supply amount Gk of the new aggregate. 86a calculates the optimum supply amount Gkx of the new aggregate by correcting the supply amount Gk of the new aggregate for each of the storage bins 15a to 15e so that the total aggregate particle size Yj is included in the optimum particle size range.
