摘要
参照国外长寿命路面结构,对我国长寿命沥青路面结构组合设计进行了探讨。认为路面结构极限应变的存在是长寿命路面设计理念的基础,提出路面基于抗疲劳和抗永久变形的结构组合原则,并根据国外典型结构组合提出长寿命路面结构组合设计框架,同时提出路面各结构层须分功能进行设计,最后提出了路面设计的3个力学指标,对我国长寿命路面结构组合设计具有重要借鉴作用。
According to perpetual pavement structure of foreign country,it was discussed about the perpetual pavement structure combination design in China. It was thought that the existence of ultimate strain of pavement structure was the base of perpetual pavement design concept. The pavement structure combination principle was put forward based on fatigue resistance and rutting resistance. A design frame of perpetual pavement combination design was put forward according to representative structures of foreign country. And it was put forward that the different structural layers of pavement should be designed differently according to their functions. Finally, the mechanical criterions of pavement design were put forward, which can be used for an important reference of perpetual pavement combination design in our country.
