摘要
研究了不同掺配工艺(干法和湿法)对天然岩沥青改性沥青混合料路用性能的影响,分析了在室内拌和条件下和现场拌和条件下,不同掺配工艺对沥青混合料水稳定性、高温稳定性和低温抗裂性的影响。结果表明湿法和干法两种掺配方法对沥青混合料的各项路用性能影响不明显,施工时可以根据拌和场的实际生产条件选择一种经济合理的掺配工艺。
This paper analyses the effects of manufacturing process of different modified asphalt （＇ dry＇ process and ＇ wet＇ process） on mixture properties.Mixtures are blended using different processes in laboratories and mixing plants, and their water stability, high temperature and low temperature properties are also tested.The results show that ＇dry＇ and ＇wet＇ processes have no significant effects on the mixture properties, and an economic and convenient manufacturing process could be selected based on the mixing plant type.
