依据Excel内置的规划求解功能,进行沥青混合料配合比的设计,并在配合比设计的基础上进一步分析,根据调整后的合成级配曲线反算集料用量的可能性。结果表明,利用规划求解反算集料用量是得不到正确的结果。 According to Excel’s built-in planning solution function, the mix design of asphalt mixture is carried out. Based on the mix design, further analysis is carried out, and the possibility of aggregates usage is calculated according to the adjusted composite gradation curve. The result shows that the correct result can not be obtained by using the solution of the plan to back-calculate the aggregate consumption.
