Steel plate-asphalt concrete composite pavement structure and construction method
The invention discloses a steel plate-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 perforated steel plate 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 direction of the whole lane; the steel plate bulges can be arc-shaped, broken-line-shaped or groove-shaped; holes are formed in the steel plate, the holescan be arranged in parallel or in a quincunx shape, the diameter of the holes is larger than the maximum particle size of corresponding types of asphalt concrete aggregates, the bottom face, the middle, the top face and the side face of the paved and compacted steel plate are all tightly bonded with asphalt concrete, and the steel plate-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 arenot required to be added; before fine-grained asphalt concrete or medium-grained asphalt concrete is paved, prefabricated convex perforated steel plates are placed on two wheel rails of each lane orthe 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板‑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带孔钢板，钢板凸起的形状可设成弧形、折线型、槽型，钢板上设有孔洞，孔洞可并列布置也可梅花形布置，孔洞的直径大于相应类型沥青混凝土集料的最大粒径，摊铺和压实后钢板的底面、中间、顶面、侧面都紧粘着沥青混凝土，形成钢板‑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带孔钢板，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。
