This paper presents a state-of-the-art review of the utilization of reclaimed asphalt pavement (RAP) aggregates in roller compacted concrete pavement (RCCP) mixes. Owing to the cost-effectiveness and fast-to-construct feature of RCCP, the utilization of RAP in this paving technology seems to be the next best option. In this paper, several issues and factors affecting the fresh and hardened properties of RCCP mixes due to the incorporation of RAP is discussed. Based on this review, it was observed that the type and age of RAP, the concentration of asphalt and agglomerated particles, gradation of RAP, compaction types and efforts, and the RAP replacement levels can significantly affect the strength and durability of RCCP mixes. From a sustainable point of view, most researchers recommended that up to 50% of RAP could be used to partially substitute natural aggregates in RCCP mixes. In a nutshell, the utilization of RAP in RCCP mixes would not only provide economic benefits but would also serve environmental benefits like reduction in the RAP stockpiles and carbon footprints, respectively.

本文介绍了碾压混凝土路面（RCCP）混合料中再生沥青路面（RAP）骨料的利用情况。由于RCCP具有成本效益和易于构建的特点，在这种摊铺技术中使用RAP似乎是下一个最佳选择。本文讨论了由于加入RAP而影响RCCP混合物的新鲜和硬化性能的几个问题和因素。根据此评论，可以观察到RAP的类型和年龄，沥青和团聚颗粒的浓度，RAP的等级，压实类型和工作量以及RAP的替代水平会显着影响RCCP混合物的强度和耐久性。从可持续的角度来看，大多数研究人员建议最多使用RAP的50％来部分替代RCCP混合物中的天然骨料。简而言之，在RCCP混合物中使用RAP不仅会带来经济利益，而且还会带来环境收益，例如分别减少RAP库存和碳足迹。
