Cold area asphalt concrete deck pavement technology research

As the problem of asphalt concrete bridge deck pavement is becoming more and more serious, how to improve its road performance has become the focus of the study. As the lack of shear strength and bond strength between layers, flaking, raveling and other diseases were occurred on steel bridge deck asphalt pavement. This paper combines the common damages of bridge deck and asphalt concrete pavement in cold area of northeast region, focuses on the analysis of the cause of asphalt concrete pavement damage causes, puts forward preventive measures and recommendations, and present the bridge deck pavement structure in cold area combined with the engineering practice.
