| 摘 要： | 柔性基层沥青路面结构具有较好的承载能力,在抵御水损坏方面比半刚性基层结构具有更好的表现。采用级配碎石基层,可以明显减少沥青路面的开裂;特别是半刚性基层沥青路面的反射裂缝问题。通过便携式落锤弯沉仪(PFWD)对某高速公路柔性基层强度进行检测,得到级配碎石柔性基层回弹模量分布,并根据检测数据,着重分析了柔性基层离析问题及其施工控制方法。

| Abstract: | The flexible base has better carrying capacity for asphalt pavement, also has better anti-water damage performance than the semi-rigid base. Application of graded crushed stone base can obviously decrease the amount of pavement cracking, and avoid the reflective cracks resulting from the semi-rigid base. This paper based on the PFWD to evaluate the flexible base of an expressway, discussed the segregation of flexible base and whose construction control methods according to the test results. |
