摘要：
The use of Cold Asphalt Mixtures (CAM) usually results in financial and environmental saving, while decreasing pollution and occupational hazards. However, they require a length of curing time to reach their full potential. Regarding ecological and financial implications, CAM can be further improved when produced with 100% recycled materials from Construction and Demolition Waste (CDW). In this paper, the evolutionary properties of CAM with CDW were studied in terms of stiffness growth and water loss and the results were compared with conventional control mixes. Among other conclusions, the results showed that although CAM with CDW lost water during longer curing periods, higher stiffness can be obtained with COW than with Natural Aggregates (NA) at any curing time.
