Paving method of composite pavement structure
The invention discloses a paving method of a composite pavement structure. The paving method comprises the following steps: paving a broken stone hardcore; laying a lean concrete base layer; laying an isolation sliding layer; laying an assembly type prestressed concrete lower surface layer; further, the method comprises the steps that the side plates and the middle plate are prefabricated; the side plate, the plurality of middle plates and the side plate are sequentially mounted from head to tail; a gap of 18-22 cm is reserved between every two adjacent longitudinal plates and used for arranging a self-stress seam; gaps of 2-3 cm are reserved between the edges and the semi-rigid asphalt pavements on the two sides; the self-stress seam is treated; pouring a leveling layer; asphalt mortar joint treatment; laying an adhesive layer; and paving the high-modulus asphalt concrete upper surface layer. Correspondingly, the invention further provides a maintenance method for the damaged pavement structure. The composite pavement structure formed by the paving method or the maintenance method is longer in service life and higher in safety.
本发明公开了一种复合路面结构的铺设方法，所述铺设方法包括：碎石垫层铺设；贫混凝土基层铺设；铺设隔离滑动层；铺设装配式预应力混凝土下面层；进一步的，该步骤包括：预制边板和中板；按照边板、若干中板、边板的顺序由首至尾依次安装；纵向相邻板间预留有18cm‑22cm的间隙，用于设置自应力缝；边缘处，与两侧半刚性沥青路面之间预留2cm‑3cm的空隙；对自应力缝进行处理；灌注调平层；沥青砂浆接缝处理；黏层铺设；高模量沥青混凝土上面层铺设。相应的，本发明还提供了一种损坏路面结构的维修方法。采用本发明铺设方法或维修方法形成的复合路面结构使用寿命更长、安全性更高。
