摘要： 通过FWD弯沉盆数据，分析了二广高速公路湖北襄荆段路面分层结构情况。结果显示襄荆高速公路的土路基情况良好，有效回弹模量主要在180 MPa和250 MPa 之间，能在交通荷载作用下对其上面的路面结构层提供好的承托。

Abstract: The pavement structural information of Xiangjing Expressway in Hubei is analyzed and evaluated with the defection basin data collected from the Fall Weight Deflectometer (FWD) tests using the modulus calculation software. The resilient modulus of the structure layers is back calculated. The results indicate that the effective resilient modulus varies between 180 MPa and 250 MPa, which suggest the sugrade soil within the project limits is fairly good and can satisfactorily provide the necessary support the overlying pavement structural layers under the traffic loads.
