| Abstract: | Purpose of research:that's to research road usage performance of cooling recycled lime-fly ash asphalt materials;Methods of research:Seeing also"Test Program for Stable Materials of Unorganic Binder for Highway Engineering"(JTJ057-94)as well as "Test Program for Asphalt for Highway Engineering and Asphalt Mixture"(JtJ052-2000),the paper analyzes composition of original road materials,and preliminarily evaluates behavior of cooling recycled lime-fly ash asphalt materials by way of tentative studdy of washout performance,cleavage strength and unconfined compression strength of cooling recycled materials with different proportionings;Results of research:the unconfined compession strength and cleavage strength of cooling recycled materials add with prolongation of curing age,the wash-resistance of cooling recycled materials is not as good as one of standard lime-fly ash macadam.Conclusions of research:the cooling recycled limefly ash asphalt materials could basically satisfy specification's needs for semi-rigid base of asphalt pavement. |
| Keywords: | Cooling recycling Fly ash of low activity Unconfimed compression strength Cleavage strength Washout performance |
