Novel assembly type pavement composite structure for pavement maintenance and construction method of novel assembly type pavement composite structure
The invention discloses a novel assembly type pavement composite structure for pavement maintenance and a construction method thereof. The structure is composed of a structural layer obtained after finish milling of an old road, a flexible leveling transition layer, a concrete prefabricated slab structural layer, a stress absorption functional layer and an ultra-thin overlay wearing layer. A flexible leveling transition layer is laid on a structural layer after finish milling of an old road, then concrete prefabricated slabs are installed and spliced, a concrete prefabricated slab structural layer is obtained after connection between the concrete prefabricated slabs and slab joint treatment, an anti-crack patch is laid, and a stress absorption layer and an ultrathin cover wearing layer are sequentially laid. The invention focuses on key technologies such as a flexible leveling transition layer fine leveling method, a concrete precast slab efficient load transfer connection method, a durable anti-seepage joint filling method between concrete precast slabs, an ultrathin cover surface anti-sliding and anti-cracking construction method and the like, and establishes a perfect fabricated pavement novel combined structure and system for pavement maintenance. And the blank of large-scale application of the fabricated pavement technology in the highway field is filled.
本发明公开了一种路面养护用装配式路面新型组合结构及其施工方法，所述结构由旧路精铣刨后的结构层、柔性找平过渡层、混凝土预制板结构层、应力吸收功能层、以及超薄罩面磨耗层组成；在旧路精铣刨后的结构层上铺设柔性找平过渡层，再将混凝土预制板进行安装、拼接，经过混凝土预制板间连接及板缝处理后得到混凝土预制板结构层，铺设抗裂贴并依次铺设应力吸收层和超薄罩面磨耗层。本发明聚焦柔性找平过渡层精找平方法、混凝土预制板高效传荷连接方法、混凝土预制板间耐久防渗填缝方法、超薄罩面抗滑抗裂施工方法等关键技术，建立了完善的一种路面养护用装配式路面新型组合结构及体系，填补装配式路面技术规模化应用于公路领域的空白。
