The construction of road infrastructure is one of the most polluting activities that exists today. Therefore, the use of waste from other industries is an excellent solution, since it reduces the consumption of raw materials, reduces CO₂ emissions and avoids the disposal of waste in a landfill. In this study, electric arc furnace slag, cellulose fibers from the papermaking industry and bitumen emulsion were used for the conformation of sustainable and porous bituminous mixtures. Electric arc furnace slag was used as a high-resistance aggregate with a capacity sufficient to support traffic loads. Cellulose fibers were added to increase the percentage of binder in the mixture without bleeding problems, thereby achieving greater tensile strength. To do this, first the waste was physically and chemically characterized, then different mixtures were conformed and finally the mixtures were studied by means of the loss by wear and Marshall tests. The results reflected an optimal combination of materials that provided the best results in the mechanical tests, obtaining much better results than the mixtures with discontinuous grading and traditional bitumen emulsion. Therefore, a sustainable, porous and economical mixture for road use is obtained in this research.

中等交通道路沥青乳液，电弧炉渣和纤维素纤维沥青的研制。

道路基础设施的建设是当今污染最严重的活动之一。因此，使用其他行业的废物是一个很好的解决方案，因为它减少了原材料的消耗，减少了CO ₂排放并避免将废物弃置于垃圾填埋场。在这项研究中，电弧炉炉渣，造纸工业的纤维素纤维和沥青乳液被用于可持续和多孔沥青混合物的构造。电弧炉炉渣被用作高电阻骨料，其容量足以支撑交通负荷。添加纤维素纤维以增加混合物中粘合剂的百分比而不会出现渗出问题，从而获得更大的拉伸强度。为此，首先对废物进行物理和化学表征，然后确定不同的混合物，最后通过磨损和马歇尔试验对损失进行研究。结果反映了在机械测试中提供最佳结果的材料的最佳组合，与具有不连续分级和传统沥青乳液的混合物相比，可获得更好的结果。因此，在这项研究中获得了一种可持续的，多孔的，经济的道路使用混合物。
