冷沥青混合料(CAM)的使用通常可以节省资金和环境，同时减少污染和职业危害。然而，它们需要一段时间的固化才能达到其全部潜力。在生态和财务影响方面，如果使用100%从建筑和拆卸废物(CDW)中回收的材料来生产CAM，则可以进一步改善。本文从刚性增长和失水两个方面研究了带CDW的CAM的演化特性，并与常规控制混合料进行了比较。在其他结论中，结果表明，尽管含有CDW的CAM在较长的固化时间内失水，但在任何固化时间，CDW都可以获得比天然集料(NA)更高的硬度。
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 CDW than with Natural Aggregates (NA) at any curing time.
