抗裂性水泥稳定碎石基层的设计与应用

Design and Application of Crack Resistance of Cement Stabilized Macadam Base

针对目前水泥稳定碎石基层抗裂性不足问题,分别用重型击实和振动压实方法对设计的水泥稳定碎石基层混合料进行了力学性能及抗裂性能的对比分析,研究表明:采用振动压实法较重型击实法设计的水泥稳定碎石基层具有更好的力学性能及抗裂性能,并在西南某机场跑道基层工程应用中印证了这一结论。

Aiming at the problem of cracking of cement stabilized macadam base, the mechanical properties and anti-cracking performance of designed cement stabilized macadam mixture are compared and analyzed by the heavy compaction and vibratory compaction method respectively. Research shows that cement stabilized macadam by the vibration compaction method has better mechanical properties and crack resistance than the heavy compaction method, which has been proved through an airport runway project in southwest China.
