| 摘 要： | 如何合理的利用FWD测得的数据来评定路面寿命是道路研究的一个重要课题。依托实体改扩建工程，使用FWD检测路面的弯沉，采用三层和四层体系来反算结构层模量，比较反算结果后，使用三层体系反算的模量值进行沥青路面剩余寿命的预估。

| Abstract: | How to reasonably use FWD measured data to evaluate pavement life is an important subject in highway research. Depending on a reconstruction and expansion project, pavement deflection is detected using FWD and the modulus of structural layer is inversed using three-layer and four-layer system. Through comparison, it is shown that the modulus inversed from three-layer system is preferred to predict asphalt pavement remaining life. Finally, es and Ez are separately determined using the theory of elastic layered system, and then substituted into the model established by the Asphalt Institute （AI）. Thus asphalt pavement remaining life can be predicted. |
