The Application Of Vibratory Compaction Technology In Bituminous Pavement

This article based on the practice projects of Shi jia zhuang city, Research to the early time destruction phenomenon of asphalt mixture at present,such as Dehiscence, flaking, water harm and so on;Unifies the asphalt mixture characteristic and the asphalt pavement characteristic, the design method of the asphalt mixture at present;study the compaction void ratio, VMA and VFA and the other volume parameter has the important influence with the performance of asphalt mixture's mechanics performance, construction performance and pavement performance. Analysis researchthe relation of each other and request of Compactness, percentage of voids and smoothness.Discussed the characteristic of GTM and the Superpave Asphalt mixture design method and the project usability shallowly. Proposed the topic of uses the oscillatory compaction method to compact the Asphalt pavement, and has carried on the massive experiments.Study in the compaction principle of the pneumatic compaction and the vibratory compaction to compact the Asphalt pavement,Research to the compaction principle of oscillatory compaction, the action mechanism of the oscillatory turn to the Asphalt mixture, in the practice projects of Shi jia zhuang city, To the asphalt pavement compactness, compactness targets and, compactness influence depth, percentage of voids and smoothness, have made the comparison test of oscillatory compaction and vibratory compaction, and has conducted the analysis research; analyzed the effect of oscillatory compaction and vibratory compaction in same compaction scheme, studied to the characteristic of the oscillatory compaction technology, fast enhanced the bituminous mixture compactness rate of increment, has guaranteed the bituminous mixture compactness fully, and effective enhancement bridge floor smoothness .Analyzed to the feasibility and the superiority of oscillatory compaction in the compaction of Asphalt mixture. Proposed the construction quality control plan of oscillatory compaction to Asphalt pavement on the projects of Shi jia zhuang city...
