Stabilized Emulsions (SE) is a Warm Mix Asphalt (WMA) technique that reduces mixing temperatures to approximately 100 °C, the range of WMA with the greatest reduction in temperature compared to Hot Mix Asphalt (HMA). The term ‘stabilized’ refers to the good storage stability of the stabilized emulsion compared to that of common emulsions. Another technique that reduces the environmental impact of asphalt mixtures is the addition of reclaimed asphalt pavement (RAP). This paper presents the research results in which the performance of SE-WMA with different amounts of added RAP were evaluated. SE-WMA was produced at 100 °C, and could be prepared with high RAP contents, reducing the consumption of virgin materials and lowering energy needs. The laboratory study and a pavement trial section were used to evaluate the performance of SE-WMA in comparison with HMA. The experimental results indicated that the physical and mechanical properties of SE-WMA, without RAP, are similar to conventional HMA, showing that the effect of reducing mixing temperature does not significantly affect the quality or performance of these asphalt mixtures. The performance of SE-WMA with 25% and 44% RAP, was slightly lower than that obtained from conventional HMA. However, the quality of the SE-WMA complied with the requirements of conventional HMA, indicating that SSE-WMA with up to 44% RAP content is suitable for pavement construction. Deflections measured in the HMA and SE-WMA trial sections without RAP and with 25% RAP showed similar results, although the SE-WMA with 44% RAP showed 8% higher deflection. The energy consumption to produce one ton of asphalt mixture calculated using a thermodynamic model showed that SE-WMA is effective for the reduction of energy consumption in asphalt plants. Overall, the study concludes that SE-WMA with RAP is a sustainable material for pavement construction that could save energy and consume less virgin material than conventional HMA pavements.

稳定乳液（SE）是一种热拌沥青（WMA）技术，可将混合温度降低至约100°C，这是与热拌沥青（HMA）相比温度降低幅度最大的WMA范围。术语“稳定的”是指与普通乳液相比，稳定的乳液具有良好的储存稳定性。减少沥青混合物对环境的影响的另一种技术是添加再生沥青路面（RAP）。本文介绍了研究结果，其中评估了SE-WMA在不同添加RAP量下的性能。SE-WMA的生产温度为100°C，可以制备高RAP含量的产品，从而减少了原始材料的消耗并降低了能源需求。实验室研究和路面试验部分用于评估SE-WMA与HMA的性能。实验结果表明，不使用RAP的SE-WMA的物理和机械性能与常规HMA相似，表明降低混合温度的作用不会显着影响这些沥青混合物的质量或性能。具有25％和44％RAP的SE-WMA的性能略低于从常规HMA获得的性能。但是，SE-WMA的质量符合常规HMA的要求，这表明RSE含量高达44％的SSE-WMA适合于路面施工。在没有RAP且RAP为25％的HMA和SE-WMA试验部分中测得的挠度显示出相似的结果，尽管具有44％RAP的SE-WMA的挠度高8％。使用热力学模型计算出的生产一吨沥青混合物的能耗表明，SE-WMA可有效降低沥青厂的能耗。总体而言，研究得出的结论是，带有RAP的SE-WMA是一种可持续的人行道建筑材料，与传统的HMA路面相比，它可以节省能源并消耗更少的原始材料。
