摘要：

Natural aggregate is the primary ingredient of asphalt concrete and Portland cement concrete mixtures. Recycled concrete aggregate (RCA) derived from demolition wastes can be used in asphalt mixtures to eliminate potential problems arising from disposing these materials and conserve natural aggregate resources. This study presents methods for using RCA in asphalt mixtures based on repeated creep tests. The standard Marshall mixture design method is revised to prepare specimens satisfying the minimum size and aspect ratio requirement in uniaxial testing. The study shows that addition of RCA can improve the resistance of mixtures to permanent deformation and hence, rutting depending on mixture gradation. (C) 2014 Elsevier Ltd. All rights reserved.
