摘要:
本文通过试验对不同级配对温拌橡胶沥青混合料路用性能的影响规律进行研究.对各粒径集料含量进行调整，选取四种具有代表性的沥青混合料：最佳油石比分别为6.7%、7.5%、6.5%和7.4%.研究了不同级配下各沥青混合料的高温、低温、疲劳性能和水稳定性能，结果表明：亚利桑那州的沥青混合料具有更好的高温性能、疲劳性能及水稳定性能；适当提高2.36~4.75 mm含量可提高混合料的路用性能；可结合地区具体条件选择合适的沥青混合料进行设计和施工.最后，采用最大理论密度曲线对本文的研究结果进行了验证.
Abstract:
In this paper, the influence of different gradations on the road performance of warm-mix rubber asphalt mixture is studied through experiments. Four representative asphalt mixtures were selected by adjusting the aggregate content of each particle size: the optimum asphalt-aggregate ratio is 6.7%, 7.5%, 6.5% and 7.4%. By studying the high-temperature performance, low-temperature performance, fatigue performance and water stability of asphalt mixtures with different gradations, the results indicated that the asphalt mixture grading proposed by Arizona has better high temperature performance, fatigue performance and water stability performance, and the road performance of mixtures can be improved by properly increasing the content of 2.36~4.75 mm. Combined with the specific conditions of the area, a right asphalt mixture can be selected for design and construction. Finally, the maximum theoretical density lines were used to verify the results of this study.
