不同基层对沥青路面车辙影响的对比分析

Comparative analysis on asphalt pavement rut of different base

结合实际观测的气温和测定的路用材料的力学参数,使用ABAQUS有限元模型,研究了柔性基层、半刚性基层和复合基层对沥青路面车辙的影响,结果表明,复合基层兼有半刚性基层和柔性基层的优点,是较好的选择。

Combination with the actual temperature and road material mechanics parameters,used the model with finite element software ABAQUS to study the effect of flexible base,semi-rigid base and compound base on asphalt pavement rut.The results show that compound base has the advantages of semi-rigid base and flexible base.It’s the better choice.
