摘要：
Cold asphalt mixtures (CAM) with 100% recycled aggregates from construction and demolition waste (CDW) were researched to ecologically and economically improve cold asphalt mixtures. The present study indicates that the UCS, ITS, ITSM and moisture susceptibility were very satisfactory not only compared with a control mix with 100% natural aggregates (NA) but also with values given by different standards and recommendations. A new global approach to design these aggregates has also been explored because conventional methods are inaccurate in this case. (C) 2013 Elsevier Ltd. All rights reserved.
