Overview of bituminous mixtures made with recycled concrete aggregates
چکیده انگلیسی


• Recycled concrete aggregates (RCA) have poor quality than natural aggregates.
• A review on the properties of hot-mix asphalt (HMA) with RCA is conducted.
• Most studies report a high stripping potential of these mixtures.
• Several treatments help mitigate its unsatisfactory moisture damage resistance.
• Test stretches of HMA with RCA exhibited good performance.

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.
