摘要
采用现有的维修方法无法从根本上解决道路破损状态,而预制预应力混凝土路面板为解决此问题提供了一种有效的途径,但是这种板造价稍高,限制了它的广泛应用,从而提出了预制预应力混凝土复合板的概念,并对其进行了技术和经济分析探讨。这种路面具有建设和维修成本低的特点,同时,施工简便,施工后可以立即恢复交通,可作为既有道路大面积维修的有效方法,也可用作新建公路的路面板,具有非常广阔的应用前景。
Precast prestressed concrete pavement is an effective path of solving the problem that the traditional repairing method can not overcome the out of repairing state of pavement fundamentally. But the price of this type pavement is expensive and it is restricted to application widely. The concept of precast prestressed concrete composite pavement is presented and the technical and economical feasibility of this type pavement are discussed and analyzed. It has low cost during the period of construction and maintenance. In the meantime, the construction procedure is convenient and the pavement can be used as soon as the construction complete. The new type pavement can be used as a effective method of repairing the large area of completed pavement as well as building new road. It has very broad application prospect.
