| 摘 要： | 目前,我国高速公路早期破坏现象日趋严重,采用沥青稳定柔性基层厚长寿命沥青能为解决我国高速公路的早期破坏提供新的思路.但我国目前的以半刚性基层为基础发展起来的静态指标路面设计方法对于长寿命沥青路面具有很大的局限性.为解决长寿命沥青路面设计中动态体系指标问题.在国内外已有研究成果的基础上提出了长寿命沥青混合料动态模量的确定方法,研究了模量对长寿命沥青路面性能的影响,为长寿命沥青路面设计方法积累了新的技术资料.

| Abstract: | The early destruction phenomenon of highway becomes serious in our country at present.The application of flexible base and thick long-life asphalt is a new method for solving the early destruction of highway in our country.The static index pavement design method based on semi-rigid base has significant limitation for long-life asphalt pavement.In order to solve the problem of dynamic system index in long-life asphalt pavement design,on the basis of achievements at home and abroad,the determination method of long-life asphalt mixture dynamic modulus is put forward and the effect of modulus to the performance of long-life asphalt pavement is studied,which accumulates new technological data for the design method of long-life asphalt pavement. |

| Keywords: | long-life asphalt pavement design dynamic modulus |
