冷再生混合料垂直振动成型法设计与评价
Design and evaluation of cold recycled mixture by vertical vibration forming method
摘要
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 relia-bility 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关键词
