Asphalt concrete pavement premature diseases mainly include moisture damage and rutting damage, etc. Internal performance?early diseases?is mainly to reduce?adhesion?between asphalt and aggregate, but diseases are caused by many factors, such as the defects of pavement structure itself, the rapidly expansion of traffic, the scale of vehicles and the large temperature difference in summer and winter, the climate changing, etc. So, it is impossible ?to solve the problem of early diseases from a single solution. the prevention of early diseases?has foresight,?prospective,?initiative, rationality.?This paper expounded the development process of high grade highway in China, analyzed the mechanism of production of various kinds of premature diseases of asphalt concrete, and put forward the comprehensive prevention and control measures of premature diseases. Key words: semi rigid base, asphalt concrete, moisture damage, rutting damage. 目 录 第一章 绪论 1 1.1 研究意义 1 1.2.1 国内研究 1 1.2.2 国外研究： 2 1.3 研究内容 4 第二章 中国高等级公路发展史 5 2.1 我国高等级公路发展历程 5 2.2 我国道路发展历程中的主要理论 6 第三章 半刚性基层沥青路面成为我国主要路面结构型式的原因分析 7 3.1 半刚性基层的概念及主要特
