Effects of recycled concrete aggregate on stiffness and rutting resistance of asphalt concrete
HighlightsTen asphalt mixtures with partial substitution of natural aggregate by RCA produced.The optimum bitumen content increases with increasing RCA content.Volumetric compositions of asphalt mixtures meet relevant technical requirements.The amount of used RCA has no significant influence on the rutting resistance.Asphalt mixtures with RCA have a lower stiffness modulus.
AbstractThe objective of this research was to assess the possibility of using recycled concrete aggregate (RCA) in asphalt mixtures. The experimental research included 10 asphalt mixtures with partial natural aggregate substitution by RCA, which ranged from 15% to 45% of fine (⩽4mm), coarse (4/22.4mm) and both fine and coarse aggregate. The optimum bitumen content increased with increasing RCA content. The use of RCA had no significant influence on the permanent deformation, while the stiffness modulus of asphalt mixtures with RCA was lower compared with the control mixture, especially at high frequencies. The results indicate that RCA can be successfully used in asphalt mixtures.
