摘要

城市垃圾分类收集所得有机组分主要由脂肪酸、中等分子量碳氢化合物和纤维素组成。这种特殊的成分使我们深入了解了有机废物用于改善沥青特性的可能性(可能用于道路路面的抗氧化剂，再生和/或增粘添加剂)。有机废物的处理问题是一个全球性的问题，越来越受到人们的关注。这项研究希望通过寻找方法来缓解这一问题，将这些废物部分用于更大的利益-在这种情况下，作为道路路面沥青粘合剂的添加剂。目前的研究重点是废物的使用和废物处理的FENTON工艺(用硫酸亚铁和过氧化氢溶液处理)。动态剪切流变学(DSR)和老化试验(滚动薄膜烘箱试验，RTFOT)表明，本研究中测试的两种添加剂被证明是有效的:一种可以用作增粘剂，另一种可以用作填料。

How Organic Waste Improves Bitumen’s Characteristics

The organic fraction derived from the differentiated collection of urban waste is mainly composed of fatty acids, medium molecular weight hydrocarbons and cellulose. This peculiar composition gave us insight into the possible use of organic waste to improve bitumen’s characteristics (possible antioxidant, regenerating and/ or viscosifying additive for road pavements). The issue of the disposal of organic waste is a global one and it’s constantly of increasing concern. This study looks to alleviate this problem by finding ways for this waste fraction to be utilized for the greater good- in this case, as an additive for bitumen binder in road pavements. The present study is focused on the use of waste as it is and waste treated by the FENTON process (treatment with ferrous sulphate and hydrogen peroxide solution). Dynamic Shear Rheology (DSR) and aging tests (Rolling Thin Film Oven Test, RTFOT) showed that two of the additives tested in this study proved effective: one can be utilised as a viscosifying agent and the other can be us ed as a filler.
