摘要

摘要研究材料变异性对温拌沥青(WMA)性能的影响，对于了解降低生产温度的效益具有重要意义。本研究比较了由两种不同的基础粘合剂和两种不同的骨料源制备的五种不同的WMA混合物的性能。分别采用循环压缩试验、间接拉伸开裂试验和改进Lottman试验对沥青混合料的车辙、疲劳和水分敏感性进行了评价。并对生产过程中的能耗进行了理论分析比较。结果表明，WMA的性能与基材粘结剂类型、骨料来源和WMA技术类型有关。尽管如此，与热拌沥青(HMA)相比，所有的WMA混合料都节省了更多的能源。基于本研究中使用的排名框架，建议使用Rediset来获得足够的性能和更低的能耗。关键词:温混合沥青;能耗;生产温度;疲劳裂纹;湿度敏感性披露声明作者未报告潜在的利益冲突。

Suitability of warm mix asphalt (WMA) technologies based on performance and energy consumption

AbstractStudying the effects of material variability on the performance of warm mix asphalt (WMA) is important to understand the benefits of reduced production temperatures. This study compares the performance of five different WMA mixtures prepared with two varying base binders and two different aggregate sources. The rutting, fatigue, and moisture sensitivity of asphalt mixtures were evaluated using cyclic compression test, indirect tensile cracking test, and modified Lottman test, respectively. Additionally, a theoretical analysis was used to compare the energy consumption during the production process. The results indicated that the performance of WMA is a function of the type of the base binder, aggregate source, and the type of WMA technology. Nonetheless, all the WMA mixtures contributed to higher energy savings in comparison to hot mix asphalt (HMA). Based on the ranking framework used in this study, the use of Rediset is recommended to achieve adequate performance and lower energy consumption.KEYWORDS: Warm mix asphaltEnergy consumptionProduction temperaturesRuttingFatigue crackingMoisture sensitivity Disclosure statementNo potential conflict of interest was reported by the author(s).

期刊介绍： The international journal Road Materials and Pavement Design welcomes contributions on mechanical, thermal, chemical and/or physical properties and characteristics of bitumens, additives, bituminous mixes, asphalt concrete, cement concrete, unbound granular materials, soils, geo-composites, new and innovative materials, as well as mix design, soil stabilization, and environmental aspects of handling and re-use of road materials. The Journal also intends to offer a platform for the publication of research of immediate interest regarding design and modeling of pavement behavior and performance, structural evaluation, stress, strain and thermal characterization and/or calculation, vehicle/road interaction, climatic effects and numerical and analytical modeling. The different layers of the road, including the soil, are considered. Emerging topics, such as new sensing methods, machine learning, smart materials and smart city pavement infrastructure are also encouraged. Contributions in the areas of airfield pavements and rail track infrastructures as well as new emerging modes of surface transportation are also welcome.
