ABSTRACT

Porous asphalt (PA) mixture is setting off an attractive alternative to be used as surface layer in pavements due to the many profits this mixture provides in terms of noise, safety and environmental aspects. Nonetheless, its use is quite limited due to its low durability in comparison to dense graded asphalt mixtures, reason for which the incorporation of different additives is recommended. In this study, the impact of different types of binders and additives in porous asphalt mixtures are experimentally assessed. A total of 54 experimental designs were defined through the Taguchi design of experiments method. Total air voids, interconnected air voids, particle loss in dry and wet conditions and binder drain down were the responses obtained from the experimental tests. Since more than one response was obtained, three Multi-Criteria Decision-Making (MCDM) methods were performed to turn the multiple response optimisation problem into single-objective optimisation problem. Based on the experimental results and statistical analysis, polymer modified binders improve the ravelling resistance without affecting the functional performance of the mixture and without presenting the risk of binder drain down.

DOE 的组合——多准则决策分析应用于多孔沥青混合料中的添加剂评估

摘要

多孔沥青 (PA) 混合物正在成为一种有吸引力的替代品,可用作路面的表层,因为这种混合物在噪音、安全和环境方面提供了许多好处。尽管如此,与致密级配沥青混合料相比,它的耐久性较低,因此其使用非常有限,因此建议加入不同的添加剂。在这项研究中,实验评估了不同类型的粘合剂和添加剂对多孔沥青混合料的影响。通过田口实验设计方法,共定义了 54 个实验设计。总气孔、相互连接的气孔、干燥和潮湿条件下的颗粒损失和粘合剂流失是从实验测试中获得的响应。由于收到了不止一个回复,执行了三种多标准决策(MCDM)方法,将多响应优化问题转化为单目标优化问题。根据实验结果和统计分析,聚合物改性的粘合剂在不影响混合物的功能性能和不存在粘合剂流失的风险的情况下提高了抗散开性。
