摘要: 该文论述了沥青混凝土路面的设计空隙率和矿料最小间隙率的真实意义，并追索其来源和发展过程，最后明确设计空隙率应以4%为准，矿料最小间隙率应是以设计空隙率为4%前提下的规定值。这样验收空隙率才能以≤7%为准。文中并对我国沥青路面施工技术规范（送审稿）中对设计空隙率和矿料最小间隙率的规定存在的问题提出意见。

Abstract： This paper describes the real meaning of design air voids and minimal voids of mineral aggregate, and recalls their background and developing process. The conclusion is that the design air voids is based on 4% and minimum voids of mineral aggregate is based on 4% design air voids. So that the accept field air voids could be less 7%. This paper also presents different opinions to Chinese Specification for Construction and Acceptance of Asphalt Pavements (for approving edition)

Key Words：Design Air Voids；Minimum Voids of Mineral Aggregate
