该项目整合了用于设计和建造可持续人行道的再生材料的最新创新。通过诸如《京都议定书》规定的建筑保固和减少空气污染的目标等措施，越来越多的环境意识以及对提高经济和建筑效率的要求，增加了在道路上采用可持续材料的努力。这项研究的目的是开发一种系统的方法，以选择可持续的材料的最佳组合，用于沥青路面的施工。所选材料包括热拌沥青（WMA），再生沥青瓦（RAS）和再生沥青路面（RAP）。这项研究的结果旨在为选择沥青路面可持续混合材料提供指导。该项目开发的方法借鉴了先前的研究成果，将图形化建模与基于性能的可持续材料数量优化结合在一起。关于水分敏感性和车辙可能性测试结果，以及基于95％置信区间的MIM分析，无论RAS，RAP或WMA的百分比如何，沥青混合料的车辙性能和水分敏感性均无显着差异。可以通过考虑最佳WMA类型，RAS / RAP百分比和WMA生产温度的工厂排放等级来选择最佳混合物。

This project integrates recent innovations of recycled materials used in designing and building sustainable pavements. An increasing environmental awareness and the demand for improving economic and construction efficiencies, through measures such as construction warrantees and goals to reduce air pollution under the Kyoto Protocol, have increased the efforts to implement sustainable materials in roadways. The objective of this research is to develop a systematic approach toward selecting optimum combinations of sustainable materials for the construction of asphalt pavements. The selected materials,warm mix asphalt (WMA), recycled asphalt shingles (RAS), and reclaimed asphalt pavement (RAP) were incorporated in this study. The results of this research are intended to serve as guidelines in the selection of the mixed sustainable materials for asphalt pavements. The approach developed from this project draws upon previous research efforts integrating graphical modeling with optimizing the amount of sustainable materials based on the performance. With regard to moisture susceptibility and rutting potential test results, as well as the MIM analysis based on a 95% confidence interval, the rutting performance and moisture susceptibility of asphalt mixtures are not significantly different regardless of the percentages of RAS, RAP, or WMA. The optimum mixture choices could be made by the plant emission rankings with consideration of the optimal WMA types, percentages of RAS/RAP, and WMA production temperatures. The WMA mixtures prepared with 75% RAP and Advera® WMA have produced the lowest CO2 emissions among the investigated mixture types<br>
