摘　　要：基于数值优化模型,以法国高模量试验评价体系为依托,对不同旧料掺配比例下所测得的试验数据开展数值模拟优化。分析当外掺剂为EC-120时沥青混合料路用性能的变化规律,并确定外掺剂为EC-120时的最佳旧料掺配比例或最不利掺配比例,为工程实际的应用提供理论支持。Based on numerical optimization model,French high modulus test evaluation system based,the experimental data measured at different blending ratio of the old material is carry out numerical simulation and optimization. Analysis of asphalt mixture road performance change when the admixture is EC-120,and to determine the optimal proportion of old mixture when admixture is EC-120 or the most unfavorable blending ratio,providing theoretical support for practical application projects.
