Abstract:

利用Mori-Tanaka等效夹杂微观力学理论研究了沥青混合料的粘弹性能。将沥青混合料看作刚性粗集料颗粒夹杂于粘弹性沥青砂浆基体内的复合材料,对集料夹杂和沥青砂浆基体的本构方程分别进行Laplace变换成弹性问题,在Laplace空间域内应用Mori-Tanaka等效夹杂和宏观平均理论由沥青砂浆粘弹性能推导出了沥青混合料的粘弹性能。结果表明,粗集料颗粒夹杂对粘弹性沥青基体性能具有增强作用,沥青混合料粘弹本构方程可表示为粗集料增强系数与沥青基体粘弹本构方程的乘积形式。利用增强系数可以从性质较均匀的沥青基体粘弹性来预测性能较复杂的沥青混合料的粘弹性。其中增强系数大于1且随粗集料体积分数或沥青基体的泊松比增加而增大,粗集料体积分数对增强系数的增大作用远大于沥青砂浆基体泊松比对其的影响。
