Application Of Double Steel Wheel Vibration Road Roller In Assembled Prestressed Continuous Box Girder Bridge Construction Of Highway

In this paper, the Zhang Shi highway number three (Ji Meng circles) engineeringpractice to Zhangbei highway Kangbao connecting line of K48+121bridge andK57+330bridge, were selected by a continuous prestressed hollow slab bridge and aprestressed concrete continuous box girder bridge as the research object, use the roadroller--analysis method of bridge coupling vibration, dozens of different conditionsof vibratory and oscillatory roller alone or in combination with operation were tested,collected in different position of the vibration acceleration, vibration frequency,displacement, strain and dynamic data compaction degree of large, and26kinds oftypical working conditions of the key comparison and analysis, study of oscillatoryroller in highway construction especially the application of large span bridge deckpaving.Through the experiment, test and analysis, oscillatory roller can fully meet therequirement of the construction of highway asphalt pavement concrete requirements,especially with its unique advantages in bridge deck pavement. The research for thehighway pavement especially deck asphalt concrete compaction and construction roadroller is especially introduced and update the oscillatory roller, provides thetheoretical basis for the. The research results can be widely used in the construction,renovation, maintenance of asphalt pavement of expressway, a highway and thinasphalt concrete pavement, and the bridge deck construction, also can be applied tounderground pipe network of city road construction, city parking constructionengineering, remarkable economic benefits and social benefits.
