| 摘 要： | 现行沥青路面设计规范中,综合弯沉修正系数F缺乏对路面结构层数的考虑,且考虑的基层类型以半刚性基层为主。针对这种情况,本文用现场试验路段的测试数据,经回归,分析提出了新的F计算式,该式能适应新的基层结构形式及不同结构层数的路面。

| Abstract: | As the presence of difference between the deflection measured and calculated according to the elastic layer theory, synthetic modified deflection coefficient F is put forward. In the present design specification of asphalt pavement, the number of structure layer is not taken into account in the present F. Moreover the flexible base course is seldom used. A new regression formula of F is suggested according to the full-scale tests in the field. |
