Cold in-place recycling, cold central plant recycling, and full depth reclamation are cost-effective, environmentally conscious pavement rehabilitation or reconstruction techniques. Although these techniques are not new, they have not been widely adopted among state agencies. There has, however, been a recent resurgence in interest in these techniques. To date there are no national specification guidelines for these processes to assist in their widespread implementation, and those specifications that do exist often have a wide range of requirements. This paper presents the results of a review of state and local agency specifications for pavement recycling techniques and offers suggestions to help agencies achieve a better and longer-lasting product when specifying pavement recycling techniques.

冷就地回收，冷中央工厂回收和全深度开垦是经济高效的环保型路面修复或重建技术。尽管这些技术不是新技术，但尚未在国家机构中广泛采用。然而，最近对这些技术的兴趣重新出现。迄今为止，还没有针对这些过程的国家规范指南来辅助其广泛实施，并且确实存在的那些规范通常具有广泛的要求。本文介绍了州和地方代理商对路面回收技术的规范审查的结果，并提出了一些建议，以帮助代理商在指定路面回收技术时获得更好，更持久的产品。
