研究了再生混凝土骨料(Recycled Concrete Aggregate,简称RCA)与天然骨料在基本物理力学特性上的不同,结合国内外关于再生混凝土骨料应用于沥青混合料的已有成果,分析了RCA沥青混合料的马歇尔试验与耐久性。研究结果表明:RCA应用于沥青混凝土路面是可行的。最后针对再生混凝土骨料应用于沥青混凝土路面可能遇到的问题给出了相关建议,并对其应用前景做出了展望。
The difference of basic physical and mechanical properties between recycled aggregate concrete (REA) and natural aggregates was studied. Based on the previous results at home and abroad about recycled aggregate used in asphalt mixtures, the effects of RCA mixed with asphalt Marshall test of materials and durability. The results show that RCA is feasible for asphalt pavement. Finally, some suggestions are put forward for the problems that recycled concrete aggregates may encounter on asphalt concrete pavement, and the prospect of their application is put forward.
