Reinforcing mesh-asphalt concrete composite pavement structure and construction method
The invention discloses a reinforcing mesh-asphalt concrete composite pavement structure and a construction method. A right lane waiting fleet length before entering an urban road plane intersection parking line is within an urban road plane intersection parking line. A convex reinforcing mesh is arranged on a wheel rail belt of each lane in the fine-grained asphalt concrete or medium-grained asphalt concrete structure layer or in the width of the whole lane; the convex shape of the reinforcing mesh can be set into an arc shape or a groove shape; transverse reinforcements of the arc-shaped reinforcing mesh are curved reinforcements; longitudinal steel bars are straight bars, longitudinal and transverse steel bars of the groove-shaped steel bar net are straight bars; longitudinal and transverse steel bars of the steel bar mesh are threaded steel bars, the longitudinal and transverse grid spacing of the steel bar mesh is larger than the maximum particle size of corresponding types of asphalt concrete aggregates, the bottom face, the top face and the side faces of the paved and compacted steel bar mesh are tightly bonded with asphalt concrete, the protrusions are hollow and filled with the asphalt concrete, and the steel bar mesh-asphalt concrete composite pavement structure is formed. Thickness, material composition and mix proportion design of each structural layer of the asphalt concrete pavement are not required to be changed, and construction methods and construction machinery are not required to be added; before fine-grained asphalt concrete or medium-grained asphalt concrete is paved, prefabricated convex reinforcing meshes are only required to be placed on two wheel rails of each lane or the whole lane. Therefore, ruts on the asphalt concrete pavement can be effectively reduced, vehicles can be safely and stably stopped in front of the intersection, the frequency of repeated maintenance is reduced, and the service life of the asphalt concrete pavement is prolonged.
本发明公开了一种钢筋网‑沥青混凝土复合路面结构及施工方法，在进入城市道路平面交叉口停车线之前的右侧车道等候车队长度内，在细粒式沥青混凝土或中粒式沥青混凝土结构层中每个车道的轮迹带上或整个车道宽度内设置凸起钢筋网，钢筋网凸起的形状可设成弧形和槽型，弧形钢筋网横向钢筋为曲筋，纵向钢筋为直筋，槽形钢筋网的纵横向钢筋均为直筋，钢筋网的纵横向钢筋均为螺纹钢筋，钢筋网的纵横向网格间距均大于相应类型沥青混凝土集料的最大粒径，摊铺和压实后钢筋网的底面、顶面、侧面都紧粘着沥青混凝土，凸起中空也充填着沥青混凝土，形成钢筋网‑沥青混凝土复合路面结构。本发明无需改变沥青混凝土路面各结构层厚度、材料组成、配合比设计以及增加施工方法和施工机械，仅需在摊铺细粒式沥青混凝土或中粒式沥青混凝土之前在每个车道的两条轮迹带或整个车道放置预制的凸起钢筋网，即可有效减少沥青混凝土路面的车辙，使车辆在交叉口前安全平稳停车，减少反复维修的次数，延长沥青混凝土路面的使用寿命。
