准兴高速公路重载路面使用寿命预估

The Prediction of Service Life for Zhunxing Heavy-load Pavement

重载路面的寿命预估是重载路面结构设计中的关键一环,近些年车辆超载情况严重,但是对于重载路面的寿命预估却未能达到一个很好的效果。结合准兴高速公路工程实践,利用疲劳理论对水泥混凝土重载路面的使用寿命进行了分析。通过分析,提出了基于准兴高速公路重载路面的合理结构设计,为重载高速公路路面使用寿命的预估提供了借鉴。

The overloaded pavement life prediction is a key procedures in the design of the overloaded pavement structure,Recent years,overloaded vehicles in serious condition,but the life prediction for heavy- load pavement is not attain a good effect. This paper combines the actual of Zhunxing highway,analysis the heavy- load concert pavement life by fatigue theory. Through the analysis,reasonable structure design was proposed based on Zhunxing heavy- load pavement,and provide a reference for the prediction of service for others heavy- load highway pavement.
