摘　　要：我国修建的第 1批高速公路有不少是水泥混凝土路面 ,经过 10余年的使用已经进入大修期。安徽省高速公路总公司在国内首先采用冲击碾压旧路面 ,再加铺水泥混凝土或沥青混凝土工艺对路面进行大修 ,称为“冲击白 +白”和“冲击白 +黑”法。这两种方法已成功地应用在高等级公路的改造中 ,文章介绍了用后者处理路面的几种有限单元法计算模型 。Quite a few expressways that were firstly built in China are PCC pavement. After more than 10 years the pavement must be reconstructed. Anhui Province Expressway Company uses break and seat procedure to deal with old pavement. Then PCC or HMA is paved on the old one. The methods are named 'white plus white' and 'white plus black' with break and seat procedure. The two methods have successful been used in the reconstruction of the expressway. Some FEM calculate models are introduced on the second methods. The pavement working character is analyzed with the calculation results. The technology, material and structure are not involved here.
