By Using polymer modified asphalt bridge deck waterproof coating synchronous shearing spraying technology, the fiber reinforced bridge deck waterproofing adhesive layer had succeed carried out in Xisang highway bridge. Shear test was conducted in the waterproof layer structure. When completed bridge deck pavement, core was drilled and samples were carried out pull-out test. The results indicate that fiber reinforced bridge deck waterproof layer can improve waterproof coating gave resistance, crack resistance and tensile ability. The introduction of asphalt bridge deck waterproof can improve the bonding strength between the layers and the overall shear strength of the waterproof layer, enhance the overall waterproof effect and enhance the service life of asphalt layer effectively.

The use of rubber asphalt pavement as a bridge deck waterproofing adhesive layer material, the use of shear test and pull-out test analysis of the adhesive layer of rubber bitumen adhesive properties. The best rubber asphalt spraying volume has been tested, and the stress - deformation of rubber asphalt waterproofing adhesive layer has been obtained. Studies have shown that rubber asphalt has good deformation ability, suitable for bridge deck waterproofing adhesive layer materials.

The weak connection performances between the waterproof adhesive layer, the bridge deck, and asphalt pavement are important factors that cause the bridge deck slippage and upheaval and affect the safety and durability of the bridge. In this paper, styrene-butadiene-styrene- (SBS-) modified asphalt, SBS-emulsified asphalt, rubber-modified asphalt, and AMP-100 waterproof materials are selected to study the performance of the bridge deck waterproof adhesive layer in the seasonal frozen region. The shear strength and bond strength of the four waterproof adhesive materials were obtained through the shear test and pull-out test of the composite specimens composed of four kinds of adhesive materials, diatomite rubber-particle asphalt mixture, and concrete bridge deck at different dosages and temperatures. According to the priority analysis of the factors including cost, construction difficulty, and environmental protection for the four kinds of materials by using analytic hierarchy process (AHP), SBS-modified asphalt is obtained as the most suitable waterproof adhesive layer of diatomite rubber particle asphalt mixture bridge deck in seasonal frozen region.

Fatigue cracks are main damages to steel bridge deck pavement with thermosetting epoxy asphalt. By combining a high-toughness resin material with fiber woven fabrics, this study formed an ultrathin overlay of fiber-reinforced high-toughness resin to improve cracking resistance of pavement. Through theoretical measurement and bending test, this research studied change laws of bending and tensile properties of epoxy asphalt concrete after fiber reinforcement and analyzed bending strength and the maximum failure strain of beams at different temperatures. Moreover, the reinforcing effects of different fibers were discussed. It is found that bending strength, maximum failure strain, and stiffness modulus of the beams with epoxy asphalt are improved after fiber reinforcement. With the decrease of temperature, after fiber reinforcement, the mode of bending failure of the epoxy asphalt mixture (EAM) changes from brittle fracture into shear failure, accompanied with significant yield phenomenon. Furthermore, organic carbon fiber is sensitive to influences of temperature, while glass fiber is least sensitive to temperature.

<p>The application of asphaltic plug joints (APJs) for road bridges has spread worldwide. The APJ consists of polymer modified asphalt binder mixed with selective aggregates filled in the cut-out centred over the gap between bridge span ends or between the bridge deck and abutment. APJs have the advantages of being watertight and free of debris, providing a smooth seamless riding surface through the whole bridge deck for vehicles to pass over with less bump and impact. They are simple, easy, and quick to install. Nevertheless, APJs have some major disadvantages. They are soft, pliable, and weak at higher temperatures. Thus, they can deteriorate severely well in advance of their intended design life. This paper presents a new joint type, i.e. the steelframe reinforced asphaltic plug joint (SRAPJ), modified from the APJ with innovative steelframe reinforcement embedded inside it to enhance its strength and durability. The steelframe has enough vertical stiffness to match the bridge deck and enough longitudinal deformation capacity to accommodate bridge movements from thermal variations and vehicular actions. An experimental application of SRAPJs in a highway bridge and discussion on their performance are also presented. Finally, suggestion for future improvement is proposed.</p>
