摘要:
为更好地模拟乳化沥青冷再生混合料现场压实工况,采用垂直振动成型方法(VVTM)对冷再生混合料进行压实,验证了方法的可靠性。对比研究了VVTM和马歇尔法对乳化沥青冷再生混合料物理和力学特性的影响。结果表明,VVTM试件力学强度与现场芯样的相关性高达94.8%,马歇尔试件的相关性不足60%。与现行方法的成型试件相比,VVTM成型试件的最佳含水率降低10%,最大干密度提高1.8%~2.3%,乳化沥青最佳用量降低7%~10%,力学性能提高32%以上,说明VVTM比马歇尔法更适于评价乳化沥青冷再生混合料的力学性能。
Abstract:
In order to simulate the field compaction condition of emulsified asphalt mixture better,the vertical vibration forming method(VVTM)is used to compact the cold reclyled mixture,and the reliability of the method is verified. The effects of the VVTM and the Marshall method on the physical and mechanical properties of the cold reclyled emulsified asphalt mixture are compared and studied. The results show that the correlation between the mechanical strength of the VVTM specimen and the field core sample is up to 94.8%,and it is less than 60% for the Mashall specimen. Compared with the current method,the best moisture content of the VVTM moulding specimens decreases by 10%,the maximum dry density increases by 1.8%~2.3%,the optimal amount of emulsified asphalt decreases by 7%~10%,and the mechanical performance is improved by 32% at least. It is proved that the VVTM is more suitable for the evaluation on the mechanical properties of emulsified asphalt mixture than the Marshall method.
