二灰碎石的性能影响因素及设计方法的研究

Study of Performance Influence Factor and Design Method of Lime Fly-Ash Gravel

二灰碎石使用三级填充级配利用振动压实方法提高了压密性 ,在粉煤灰中Si O2 、Fe2 O3 、Al2 O3 ,含量符合要求的情况下 ,粉煤灰的细度是影响强度。

Lime fly-ash gravel with three grade filling gradation raise compactibility by vibrating compaction method,in the condition of content of Sio2,Fe2O3,AI2O3 in fly-ash in according with the requirement,the fineness of fly-ash in main factor to effect strength and frost resistance.
