摘　　要：传统水泥混凝土路面因抗压强度高、刚度较大、耐久性较强、使用寿命长而被广泛应用。然而,由于硅酸盐水泥混凝土的性质,现浇水泥混凝土路面养护时间长、强度增长慢、开放交通晚,无法满足路面快速施工的要求。因此,基于绿色建筑和智能建造技术理论开发了一种新型可循环使用的路面体系,即装配式预应力混凝土路面,通过标准化设计基础板、中央应力板和连接板,进行工厂化预制和现场模块化安装,施工速度快,施工环境不受极端天气的影响。装配式路面使用性能优异,既可广泛应用于公路新建、改扩建和养护工程,也可用于地震、泥石流等极端自然灾害条件下的道路抢修。The traditional cement concrete pavement is widely used because of its high compressive strength, large stiffness, strong durability and long service life. However, due to the properties of Portland cement concrete, i.e. long curing time, slow strength growth and late open for traffic, the cast-in-place cement concrete pavement is hard to meet the rapid construction requirements. Therefore,based on the technological theory of green building and intelligent construction, a new type of recyclable pavement system, that is the fabricated prestressed concrete pavement. Through the standardized design base plate, the central stress plate and the connecting plate, the factory-like prefabrication and the site modularized installation are carried out, which construction speed is fast and construction environment is not affected by the extreme weather, The usability of the fabricated pavement is excellent, which can be used not only widely in new construction, reconstruction, expansion and maintenance of highway, but also in emergency repair of the roads under the extreme natural disaster conditions such as earthquake and debris flow.
