Same-layer different-road pavement structure
The invention discloses a same-layer different-road pavement structure which comprises a three-layer structure, namely a lower surface layer, a middle layer and an upper surface layer in sequence frombottom to top. The middle layer is formed by splicing an overtaking lane lower surface layer, a heavy lane lower surface layer and an emergency parking lane lower surface layer left and right. The upper surface layer is formed by splicing an overtaking lane upper surface layer, a heavy lane upper surface layer and an emergency stop lane upper surface layer, the overtaking lane upper surface layeris located above the overtaking lane lower surface layer, and the width of the overtaking lane upper surface layer is 100 mm smaller than that of the overtaking lane lower surface layer. The lower surface layer is made of an AC-25 type asphalt mixture, and the overtaking lane lower surface layer is made of an AC-20 type asphalt mixture. The pavement structure can meet the use of different types of lanes, can effectively resist high-temperature ruts, water damage pits, low-temperature variability and other diseases, and solves the technical problem that the service life of a heavy lane and theservice life of an overtaking lane are not synchronous.
本发明公开了一种同层异道路面结构，该路面包括三层结构，从下向上依次为下面层、中间层和上面层，所述中间层由超车道下面层和重车道及急停车道下面层左右拼接而成，所述上面层由超车道上面层和重车道及急停车道上面层拼接而成，所述超车道上面层位于超车道下面层的上方，且所述超车道上面层的宽度比超车道下面层的宽度小100mm；所述下面层为AC‑25型沥青混合料，所述超车道下面层为AC‑20型沥青混合料。本发明的路面结构，可以满足不同种类车道的使用，可有效抵抗高温车辙、抗水害坑槽和低温可变性等病害，解决了重车道与超车道的寿命不同步的技术问题。
