An Experimental Study Of Cold Patch Asphalt Mixture Applied Tio High-performance Bridge Deck Pavement

With the rapid increase in the number of vehicles, vehicle increasingly large, he avy-duty, the bridge withstand the load level, increasing impact. In the operation proces s, the bridge deck pavement of the bridge has become the early destruction of major diseases, not only seriously affected the highway driving comfort, but has a serious impact on bridge service life. Therefore, damage should be made the bridge repair,so that will not affect the normal operation of the traffic. Current, conventional roa drepair materials mainly for general design, the bridge is difficult to adapt to the co mplex requirement and deformation, resulting in bridge is repeatedly, frequently rep aired, a serious impact on traffic and safety of the bridge. Therefore, need to find a suitable and repair deck at any time cold patch material.Cold Patch Asphalt adapt for a variety of weather and environment, and themat erial without heating, easy to use; construction is simple, fast and construction ma ch required less inery and personnel; with cement concrete, wood, metal and other materials quickly bonded, Adhesive tape wheels are not to be so very suitable for bri dge repairdefects, we should intensify research in this area.
