基于空隙率下的我国高速公路早期破坏研究

目前，我国高速公路沥青路面早期破坏严重，而空隙率是沥青混凝土性能的主要影响因素．提出了空隙率和高速公路早期破坏的概念，阐述了空隙率对我国高速公路沥青路面的重要性，从空隙率的角度分析了我国高速公路早期破坏的原因，并提出了相应解决措施，具有重要经济和社会价值，可供高速公路沥青路面设计、施工参考．

Research on the Premature Failure of Expressway in Based on Ratio of Void

At present, the Premature Failure of Expressway in China often occurs. Ratio of void is the most important factor for the workability of the bituminous pavement. In this paper the conceptions of the Ratio of void and the Premature Failure of Expressway are put forward; the importance of ratio of void is elaborated. The reasons that ratio of void caused premature failure of expressway in China are analyzed; at the same time the measures that solve the problems are put forward., which can be taken as a reference for design and construction; those are very useful for the development of the economic and the society in our country.
