【摘要】：基于沥青混合料抗压回弹模量的大小与材料的力学性能密切相关,通过收集既有的沥青混合料抗压回弹模量的数据,建立了沥青混合料抗压回弹模量的数据库,运用正态分布方法,得到了不同条件下的沥青混合料抗压回弹模量代表值.研究结果表明:沥青混合料抗压回弹模量与沥青的类型、温度条件、沥青质量分数之间的变化关系基本符合既有的研究结果,对大数据进行数学处理,获得的代表值具有较好的代表性;利用数学回归方法,建立不同条件下的沥青混合料抗压回弹模量预测方程,经过验证,所建立的沥青混合料抗压回弹模量对数模型具有较高的拟合精度与再现性.
[Abstract]:Based on the fact that the modulus of compressive resilience of asphalt mixture is closely related to the mechanical properties of the material, the database of the modulus of resilience of asphalt mixture is established by collecting the existing data of the modulus of resilience of asphalt mixture. By using the normal distribution method, the representative modulus of compressive resilience of asphalt mixture under different conditions is obtained. The results show that the relationship between the compressive resilience modulus of asphalt mixture and the type, temperature condition and asphalt mass fraction of asphalt mixture basically accords with the existing research results. The representative values obtained are more representative, and the prediction equations of compressive resilience modulus of asphalt mixture under different conditions are established by mathematical regression method, and verified, The logarithmic model of compressive resilience modulus of asphalt mixture has high fitting accuracy and reproducibility.
