路面底基层材料二灰砂后期强度的研究

A Study on the After Strength of Lime_Fly Ash and Grains of Stone as the Material for Subbase of Pavement

论述了二灰砂的强度随龄期的增长而变化的规律，后期强度与早期强度的相对关系，以及压实程度、石灰质量等因素对后期强度的影响。

The after strength of the material which is a compound of lime, fly ash and grains of stone was studied in this paper. The content of study was the change of after strength with the change of age, the relative relation between after strength and early strength, influence on strength by degree of compaction or quality of lime.
