Experimental Research on Road Usage Performance of Materials for Subbase of Cement,Lime,Fly Ash Washed out by Seawater and Macadam Road

Purpose:it's to study application of fly ash washed out by seawater in road's subbase.Method:Through experimental study in lab,the paper analyzes and estimates major physico-mechanical properties of materials,and the experiment of materials proportioning design is made also.Results:experimental results indicate that when the lime content amounts to 80%,the unconfined compressive strength satisfies needs for specification;when the lime content amounts to 10% and the chloride ion content in fly ash washed out by seawater doesn't exceed 1.5%,the materials possess good frost-resisting performance.Conclusions:For materials used for present experiment,so long as scientific and rational design of their proportionings,the fly ash washed out by seawater could be applied to construction of road subbase.
