| 摘 要： | 现行沥青混凝土路面设计规范中以路表弯沉为主要设计指标,并以综合弯沉修正系数调整实测值与理论值之间的偏差。鉴于考虑的基层类型以半刚性基层为主,通过对现场试验路测试数据的分析,提出了新的F计算式,适用于厚沥青混凝土层路面结构形式。

| Abstract: | As the existence of difference between the deflection measured in the field and calculated values in accordance with the elastic layer theory, synthetic modify deflection coefficient F is put forward in the present design specification of asphalt pavement. Moreover the flexible base course is seldom used. A new regression formula of F applicable to the thick layer asphalt pavemtn is suggested according to the tests in the field. |
