摘要
车辙是沥青路面主要的破坏形式之一,而层间接触状态对车辙发展规律是有影响的。借助有限元软件ABAQUS计算沥青面层层间不同接触状态下影响车辙发展规律的各项力学指标和连续7 d高温条件下的车辙发展规律。计算结果表明,沥青面层层间完全连续时,影响车辙发展规律的各项力学指标要小于不完全连续时的力学指标;沥青面层层间完全连续时连续7 d高温条件下的车辙发展速度要小于不完全连续时的车辙发展速度。因此,沥青路面施工时保证面层层间良好的接触状态,可延缓车辙的产生,提高沥青路面的使用寿命。
The rutting is one of major failures of asphalt pavement, and interfacing state can influence the rutting development rule. The finite element analysis （FEA） software ABAQUS was employed to caleulate the mechanical indexes which can influence the rutting development rule on different interfacing state of asphalt pavement surface and the rutting development rule in seven days with high temperature. The result indicates that when the interfaces of asphalt pavement surface are completely continuous, those indexes and the rutting development speed in seven days with high uous. Therefore good interfacing state of asphalt temperature are smaller than those of not completely continpavement surface in the process of construction of asphalt pavement can prolong service life of pavement and lighten rutting.
