In order to explore the potentials of a foam-based warm-mix asphalt(WMA) technology for the production of EME2 mixtures, an extenstive laboratory study was carried out. In this study EME2 mixtures incoporating 0% and 30% reclaimed asphalt (RA) were produced at 120°C using WMA technology. As control mixtures, hot-mix variants of these mixtures were also produced at 180°C. The performances of these mixtures were determined using various methods. Among others, the water sensitivity, stiffness, fatigue and resistance to permanent deformation characteristics of the mixtures were investigated. Rheological tests were also performed on virgin and recovered binders. Results showed that using the WMA method a significant reduction in production temperature can be achieved. Despite differences in production temperatures, the WMA mixtures showed equivalent performance to their hot-mix variants. Rheological results indicate the additional benefits of WMA in preserving the bitumen by limiting oxidation during production and compaction process.

为了探索基于泡沫的温拌沥青（WMA）技术在生产EME2混合物中的潜力，进行了广泛的实验室研究。在这项研究中，使用WMA技术在120°C下生产了含0％和30％的再生沥青（RA）的EME2混合物。作为对照混合物，还在180℃下产生了这些混合物的热混合变体。使用各种方法确定这些混合物的性能。其中，研究了混合物的水敏感性，刚度，疲劳性和抗永久变形特性。还对原始粘合剂和回收粘合剂进行了流变学测试。结果表明，使用WMA方法可以显着降低生产温度。尽管生产温度存在差异，WMA混合物表现出与其热混变体相同的性能。流变学结果表明，WMA在生产和压实过程中通过限制氧化来保持沥青的额外好处。
