<正>结合多年的施工经验，从材料选用、配合比设计、铺筑方法等方面分析二灰碎石基层施工中的质量控制措施。结果表明：在摊铺作业时，应保持作业的连续性；在气温较高时施工，应保证碾压时二灰碎石的含水量，并快速摊铺、碾压；施工完毕要保湿养生7d，气温较低时还需采取覆盖措施，防止表面冻坏。

The measures for controlling construction quality of lime-fly bound macadam base of pavement were studied from the respects of selecting materials, designing mix proportion and paving methods. The results as follows: the work would be continuous on spreading. In- conditions of high temperature, the moisture content of lime-fly ash bound macadam would be keeped on rolled work doing, and spreading and rolled work would be quick. After rolled work, maintenance would be kept with moisture within 7 days, in conditions of low tempera- ture, road would be covered with material to prevent it frozen.
