Structures and materials of pavement are traditionally given main focus in research oncement concrete deck pavement.Since failure due to interfacial distress sequent reported.Interfacial safety of pavement.as well as waterproof and cohesive layer draws increasinglyattention. Waterproof bonding layer of cement concrete bridge deck and asphalt concretepavement association as a whole, can effectively improve the pavement structure underconditions that play a key role in connecting link layer. Waterproof adhesive layer directlyaffects the quality of the durability of bridge structures. Waterproof adhesive layer presentstudy bridges in China has not yet formed a complete system, in the actual design of thebridge construction, there are still more randomness. In this paper, the bridge deckwaterproofing adhesive layer technology of cement concrete was study thoroughly, whichwas important for practical engineering significance.In the research, based on the analysis of the bridge deck pavement disease andwaterproof adhesive layers. Studies have shown that in the bridge deck waterproofingadhesive layer plays a key role is to ensure the durability of the bridge structure andeffective measures.Study of commonly used by the layer of waterproof adhesive material of high and lowtemperature performance, permeability and shear drawing performance. Now widely usedfor the SBS modified asphalt, SBR modified asphalt emulsion, the second-order reactionwaterproof adhesive material for basic performance test. Through high and low temperature,acid and alkali resistance test, indicating that the three kinds of waterproof materials, thetechnical indicators are in line with JT/T535-2004"Bridge Water-based asphalt-basedwaterproof coating" specifications, can be used in bridge deck waterproofing adhesive layer.The three layers of waterproof material waterproof adhesive permeability, shear andpull-out performance tests, and testing of factors affecting the specific analysis. Throughexperimental studies of the best bonding material Spraying volume, studies have shown that after gravel spill cloth waterproof layer can improve the shear strength, as the temperaturerises significantly reduced its adhesive properties. Results of the tests used by the SBSmodified asphalt as a road test material water bonding layer.
