| 摘 要： | 根据不同荷载与路面状况下弯沉的实测结果，计算并分析了按弯沉等效的轴载换算指数的变化规律。分析表明半刚性基层沥青路面轴载换算指数主要与路面结构强度和轴重有关，并由此根据实测数据分析得到了按弯沉效时半刚性基层沥青路面的轴载换算公式，供规范修订时参考。

| Abstract: | The change rules of axle exchange index based on deflection equivalent are analyzed according to the survey results in the different loads and pavement conditions. It is pointed out that the main influential factors to axle exchange index are pavement structural strength and axle's weight. And then the axle exchange formula based on deflection equivalent for semi rigid base asphalt pavement is obtained. Those can be as references in the revising design specifications of asphalt pavement. |
