Widened asphalt pavement structure of extremely heavy traffic expressway
The invention discloses a widened asphalt pavement structure of an extremely heavy traffic expressway, and particularly relates to the technical field of expressway widening, the pavement structure comprises an original road layer and a new road layer, the new road layer is located on the side edge of the original road layer, a second new road cushion layer is arranged on one side of the original road cushion layer, and a first new road cushion layer is arranged at the bottom of the second new road cushion layer; a first new road cushion layer is arranged on the original road cushion layer, a second new road cushion layer is arranged on the first new road cushion layer, a new road subbase layer is arranged on the second new road cushion layer, graded broken stones are arranged between the original road cushion layer and the original subbase layer and between the second new road cushion layer and the new road subbase layer through milling pits, a new road base layer is arranged on the new road subbase layer, expansive concrete is arranged between the new road base layer and the original road base layer, and a new road asphalt layer is arranged on the new road base layer. By arranging the adjusting assembly, the road rolling wheel rotates synchronously when the press body moves through the moving wheel, the two-way hydraulic cylinder is used for driving the expansion wheel to move outwards and stretch out of the inner cavity of the road rolling wheel, the width of the road rolling wheel can be adjusted according to needs, and dead corners are reduced.
本发明公开了一种极重交通高速公路加宽沥青路面结构，具体涉及高速公路加宽技术领域，该路面结构包括原路层和新路层，新路层位于原路层侧边，原路垫层一侧设置有第二新路垫层，第二新路垫层底部设置有第一新路垫层，第二新路垫层上设置有新路底基层，原路垫层和原路底基层通过铣刨坑与第二新路垫层和新路底基层之间设置有级配碎石，新路底基层上设置有新路基层，新路基层与原路基层之间设置有膨胀混凝土，新路基层上设置有新路沥青层。本发明通过设置调节组件，压路轮在压力机体通过移动轮移动时同步转动，利用双向液压缸驱动拓展轮向外侧移动伸出压路轮内腔，使得压路轮可以根据需要调整压路轮宽度，减少死角。
