摘要:
为了强化沥青路面微观结构、提高沥青路面压实度及服役性能，提出了沥青路面真空压实技术.采用理论分析与试验相结合的方法，在分析真空压实机理的基础上，设计并制造了小型真空压实样机，对沥青混合料完成了静碾压、真空静碾压、振动压实、真空振动压实四种不同工况下的对比试验.试验结果表明：在相同试验条件下，采用真空压实时，得到的沥青路面中沥青饱和度更大、矿粉空隙率和路面空隙率更小且需要的压实遍数更少；对沥青混合料进行内部结构SEM测试，发现真空压实的微观结构更致密.说明真空压实能有效强化压实过程，为提高沥青路面压实质量提供了新思路.
Abstract:
In order to strengthen the microstructure of asphalt pavement and improve the compaction degree and service performance of asphalt pavement, the vacuum compaction technology of asphalt pavement is proposed in this paper. Based on the analysis of the mechanism of vacuum compaction, the vacuum compaction prototype was designed and fabricated by the combination of theoretical analysis and experiment, and the contrast test (static compaction, vacuum static compaction, vibration compaction and vacuum vibration compaction) under different conditions was completed. The experimental results show that under the same experimental conditions, when the vacuum compaction is used, the asphalt pavement has less porosity and mineral powder porosity and more asphalt saturation, which also needs less compaction number. And it is found that the microstructure is denser under vacuum compaction by SEM test. It shows that vacuum compaction can effectively strengthen the compaction process and provide new ideas for improving the compaction quality of asphalt pavement.
