摘要：

A laboratory study of the use of recycled concrete aggregates (RCAs) from construction and demolition waste (COW) in hot-mix asphalt (HMA) for base courses in pavements was conducted. HMA mixes containing 0%, 5%, 10%, 20% and 30% RCA in place of natural aggregate were evaluated. The Marshall mix design procedure was used to develop the mixes. To improve the moisture sensitivity of the mixes, they were cured in an oven for 4 h. The results indicated that the mixes comply with Spanish moisture damage specifications. The mechanical properties (stiffness, permanent deformation and fatigue) of the mixtures were studied. The mixtures exhibited good engineering properties. Although HMA with RCA requires further investigation, the results from this study were very promising. (C) 2013 Elsevier Ltd. All rights reserved.
