Research On Waterproof And Cohesive Layer Of Asphalt Concrete Pavement For Concrete Bridge Deck Of Large Longitudinal Slope

The waterproof and cohesive materials of the bridge deck pavement have come to very important and important in the system of the bridge. It is the setting of the waterproof and cohesive materials of the bridge deck pavement that has been demanded in our specifications. However, the whole designing-ideology of the waterproof and cohesive materials is based on the experience of designer and is validated by the experimentation. And it is on the initial stage. The State road which is buit at the west of China is built at the Cold-mountainous area where has rigour climate, large longitudinal slope and great volume of traffic. Is this area, when the truck-lord run on the bridge, the stress in the deck pavement becomes very complexity because of the deck pavement itself. So, it is demanded further standard. This research is based on the project of Guozigou-Xinjiang, including its traffic composition.First of all, doing calculate structural mechanics of deck pavement, knowing that the coherent layer system influences the stress and strain of deck pavement. Coherent layer material which owes good performance and appropriate design of deck pavement can effectively reduced early destruction of the bridge deck pavement.Secondly, the mainly research heads to find the best material by balancing the waterproof ability and the shearing strength. Including different formulation and technology.Finally simulated coherent layer real work state, carry on mechanics performance test and waterproof ability test, analyze the materials performance.
