| 摘 要： | 利用江苏省不同地区20条高速公路上2004～2006年所有货车和大客车的动态称重数据,分析确定了各自的轴载谱参数;比较了我国和AASHTO 1993水泥路面设计方法中轴载换算公式的区别,分别利用这两种方法确定了各种车型的当量轴载换算系数以及混合交通的累计轴载作用次数, 为路面结构分析和设计提供参考,并指出在参考国外相关指标和典型的路面结构时,应当注意由于国、内外水泥路面轴载换算公式不同而造成的差别.

| Abstract: | Weight-in-motion data were collected from 2004 to 2006 at 20 expressways in Jiangsu province,and load spectra parameters were determined.The difference between AASHTO 1993 and China ESAL calculation methods for concrete pavements were analyzed.EALFs of various types of vehicles and numbers of ESALs were determined using both methods.The results obtained in this study can be used in pavement analysis and design.It is pointed out that the difference caused by different EALF equations should be taken into account when utilizing relevant foreign index and typical pavement structures. |
