摘　　要：沥青混凝土路面大修是一项系统工程,无论是从旧路面损坏状况的检测、评估、大修方案的确定,还是从沥青及沥青混合料的选择、旧路面的处治、加铺层的质量控制,都应进行统筹考虑。以首都机场高速公路大修工程为依托,详细论述了大修工程设计中的重点和难点,为今后的路面大修工程积累设计经验。Compared with the experience of new constructed pavement design, the experience of asphalt pavement heavy maintenance design is poor. Some successful experiences in asphalt pavement heavy maintenance design based on the project of heavy maintenance of Capital Airport Expressway are introduced, which involve the evaluation of pavement damage, the method of rehabilitation, the choice of asphalt and mixtures according to damage degree, and the construction.
