公路水泥混凝土再生利用是一项既有经济优势 ,又具有环保优势的新技术 ,公路水泥混凝土再生利用主要从现场再生技术过程和料厂再生技术过程两个方面研究 ,美国在实验室和现场作了大量试验 ,在许多州进行了开发利用 ,已取得大量成就。可以预言 ,公路水泥混凝土再生利用引起明显的优势在美国乃至整个世界将会越来越广泛地应用 Recycling of highway cement concrete is a new technology with both economic advantages and environmental protection advantages. Recycling of highway cement concrete mainly researches from the field regeneration technology process and the plant regeneration technology process. The United States in the laboratory and field work A large number of experiments have been carried out, many countries have carried out development and utilization, has made a lot of achievements. It can be predicted that highway cement concrete recycling caused obvious advantages in the United States and the world will be more widely used
