Abstract
[Abstract] Recycled concrete aggregates (RCA) appear to be suitable materials to use in hot-mix asphalt (HMA) for flexible road pavements. However, the poor quality of RCA results in different engineering properties of an HMA using RCA compared to mixtures composed of natural aggregates. This paper presents a review on the properties of HMA with RCA. Varied laboratory results were obtained, likely because of the heterogeneous nature and origin of the RCA. Nevertheless, a majority of the studies report a high stripping potential of RCA mixtures. Several treatments help mitigate this problem. Additionally, select test stretches of the RCA mixture exhibited good performance.
