回收旧沥青混合料冷拌再生技术的研究

Study on Cold Recycling of Asphalt Pavement

近年来 ,处理回收旧沥青混合料的问题越来越重要 ,不仅是社会经济效益的需要 ,也是环境保护的需要。本文应用正交设计方法对回收旧沥青混合料的冷拌再生影响因素进行分析 ,得出各影响因素之间的关系 ,并提出修正的马氏试验 ,给出适用的旧沥青混合料冷拌再生设计方法。

In recent years, it is more important to know how to deal with cold recycling of asphalt pavement because it is not only the need of social economic benefit but also the need of environmental protection.On the other hand, cold recycling of asphalt pavement can also be renewed in some pavements. In the paper, analysis is made of the factors that affect cold recycling of asphalt pavement with orthometric design method to get the relationship of those factors among those factors, bring forward the modified Marshell Experimentation, then give out the method to design the cold recycling of asphalt pavement.
