| 摘 要： | 考察了不同级配类型和不同成型工艺的粉煤灰级配碎石混合料性能，分别采用CBR值、永久变形和弹性模量对级配碎石混合料性能进行了评价。研究表明，掺加粉煤灰后级配碎石混合料性能显著提高，振动压实的混合料性能优于击实成型的混合料，近似间断级配的混合料性能优于连续级配混合料。

| Abstract: | In the paper, flyash grading macadam mixture performance of different grading types and compaction methods are studied. CBR, permanent deformation and elasticity modulus are adopted respectively to evaluate its performance. Test results show that the grading macadam mixture performance is remarkably increased after adding flyash, the performance of the mixture compacted by vibratory compaction method is better than that of heavy-duty hitting method and the mixture performance of approximate gap grading is superior to that of continuous grading. |
