| 摘 要： | 在公路路基与路面下底基层之间设置无粘结料的级配碎石柔性垫层,一方面能有效减少反射裂缝的产生,另一方面还能起到良好的隔温性以及排水性的作用,论文依托宝三高速公路建设项目,从级配碎石垫层配合比优化、施工质量控制两个方面介绍了级配碎石垫层在宝三高速公路的应用情况,后期观测结果表明级配碎石垫层能有效减少路面半刚性基层反射裂缝的产生频率。 |
| 关 键 词： | 级配碎石 配合比 施工控制 |

| Abstract: | There are two advantages to set a soft graded stone cushion between roadbed and road sub-base.On the one hand,it can reduce the production of reflective cracking;On the other hand,it can play a good effect of septum and drainage of warm.Based on the Bao-San expressway construction project,this paper introduced the application of graded stone cushion through mix optimization of graded hardcore and quality control of construction process.Later observations show that the graded stone cushion can effectively reduce the production frequency of reflection cracks of semi-rigid base. |
| Keywords: | graded crush stone grading construction control |
