旧水泥混凝土上加铺沥青混凝土面层,是改造旧水泥混凝土路面行之有效的方法之一,在公路的改建和扩建中大部分地区已普遍采用。虽然目前我国尚未有比较成熟的相关设计规范和方法,经验也很不足,但近年来国内许多科研、设计单位面对广大工程改造的迫切需要,在这方面的研究中取得了不少有益的、值得借鉴的经验,成功的关键在于精心设计、精心施工。 The addition of asphalt concrete pavement to old cement concrete is one of the effective ways to transform the old cement concrete pavement. It has been widely adopted in most areas in the reconstruction and expansion of highways. Although at present there are not quite mature related design norms and methods in our country, and the experience is not enough, in recent years, many domestic research and design institutes have faced the urgent need of the general engineering reconstruction. In this respect, Worth learning from experience, the key to success is well-designed, well-constructed.
