二灰碎石基层分层施工技术的试验研究

On Layer-built Technique for Lime-flyash Concrete as Base Course

在高等级道路工程中 ,二灰碎石基层有两种不同的分层施工方法 :连续分层施工法和间隔养生期分层施工法 .现行技术规范对这两种方法均认可 ,但并不明确两者的实际效果 .以上海市外环线工程为依托 ,通过试验路的实施和现场测试 ,对二灰碎石基层的分层施工技术进行了研究 .结果表明 。

On the basis of test road,two kinds of layer-built technique of lime-flyash concrete as base course were studied.It is shown that the characteristics of the base course from interrupted casting method was better than that from continuous casting method.
