回收粉尘掺配水泥级配碎石干缩性能试验研究

摘要

为了研究沥青拌合站回收粉尘对水泥级配碎石干缩性能的影响，拟定质量分数为1%～5%粉尘掺量对其进行干缩试验，并与基本型（0%粉尘）水泥稳定级配碎石进行对比分析，结果表明，小于3%的掺回收粉尘的水泥稳定碎石平均干缩应变变化小，建议掺量不大于3%。%To study the asPhalt mixing Plant to recycle the dust mixed with cement graded gravel in effect on shrinkage Performance,is now develoP the mass fraction of 1% to 5% shrinkage test its dust content and the basic tyPe(0% dust)mud stabilized grades macadam comParative analysis, studies show that the average shrinkage of less than 3% of the dust mixed with recycled cement stabilized gravel strain small changes recommen-ded dosage of not more than 3% .
