摘要

摘要本文评价了利用工业废料——高炉矿渣人工集料在一定用量下替代ab22,4沥青混合料中天然集料的可能性。此外,还提出了用含能煤燃烧产生的工业废渣(如脱硫废渣)中的粉末代替常用填料的可能性。根据规定的技术进行实验室研究和研究。为此,为了评估沥青混合料配方的性能,将通过and 605: 2016中描述的静态和动态测试进行评估。本研究结果显示了不同工业废料组成的沥青混合料的可能性。实验室试验结果表明,工业废料材料可用于设计沥青混合料,以取代一定剂量的天然材料,这种材料与通常的沥青粘结剂相互作用时表现出良好的性能。

Using the Industrial Wastes in the Base Layer of Pavement
Abstract This paper evaluates the possibility of using artificial aggregates from blast furnace slag, considered industrial waste, which can replace, in a certain dosage, the natural aggregates in the composition of an AB 22,4 asphalt mixture. Furthermore, it is presented the possibility to replace the usual filler with powders from industrial wastes such as the desulphurization waste, generated by the combustion of the energetic coal. Laboratory studies and researches are carried out according to prescribed techniques. For this purpose, for the evaluation of the performance of the asphalt mixture recipes will be evaluated by static and dynamic tests as described in AND 605: 2016. The results of this study show the possibility of using asphalt mixtures with different dosages of industrial wastes in composition. The results obtained from the laboratory tests have shown that materials from industrial waste can be used in the design of asphalt mixtures with the purpose of replacing natural materials, used in certain dosages, which demonstrates good behavior in interaction with the usual bituminous binder.
