中美规范下柔性路面设计方法比较

Comparison of Design Methods of Flexible Pavement under Chinese and American Specifications

为响应国家“走出去”号召,中国企业深入拉美地区进行道路建设.由于拉美地区多采用美国规范进行路面设计,中美规范的差异成为道路建设者面临的主要技术问题.为了方便相关人员充分理解两种规范的差别,从计算原理,计算方法,使用的材料,参数取值各方面对两种规范的设计方法进行详细对比,阐述各自优缺点,得出两国规范在计算方法及回弹模量取值等方面的差别,为同行业相关设计提供借鉴.

In response to China's call to"go global",Chinese companies have gone deep into Latin America to build roads.Because the pavement design in Latin America is mostly based on American specifications,the differences between Chinese and American specifications have become the main technical problems faced by road builders.In order to facilitate the relevant personnel to fully understand the differences between the two specifications,this paper compares the design methods of the two specifications in details from the aspects of calculation principle,calculation method,materials used and parameter values,expounds their respective advantages and disadvantages,and draws out the differences between the two specifications in calculation methods and resilience modulus values,and provides reference for related design in the same industry.
