1、前言目前对于现有路面的结构状况评价多用弯沉指标。对于某一路面结构,可方便地计算出一定荷载作用下的理论弯沉盆,又由于路表弯沉和结构参数间存在一定的对应关系,路表弯沉盆体现了路面各结构层的土基的整体刚度的强度,而且与路面的使用状态存在内在联系。对于实际应用中的
1, Foreword At present, for the evaluation of the structural condition of the existing pavement, multiple deflection indicators are used. For a pavement structure, the theoretical deflection basin under a certain load can be easily calculated. Due to the existence of certain correspondence between deflection of the pavement and the structural parameters, the deflection of the pavement reflects the soil of each structural layer of the pavement The strength of the overall stiffness of the base, but also with the use of the road there is an inherent relationship. For practical applications
