Abstract

A significant issue that researchers have been addressing recently is the recycling of various waste materials from different industries. Annually, millions of tons of waste are released. Pollution and safe, cost-effective disposal are critical issues with these waste materials. This study aims to investigate usability of concrete waste (COW) and ceramic waste (CEW) as filler material in Hot Mix Asphalt (HMA). Firstly, in this direction, a series of tests were conducted to determine the optimum bitumen content. Five different bitumen contents (i.e., 4.5%, 5%, 5.5%, 6%, and 6.5%) were used to prepare asphalt concrete samples. The Marshall Stability (MS) test was then performed on the prepared samples using various filler ratios, including limestone (LS), concrete waste (COW), and/or ceramic waste (CEW). Selecting the series of asphalt with 4% filler that has provided the maximum stability, COW or CEW was replaced with LS filler at rates of 25%, 50%, 75%, and 100%. Consequently, the use of COW or CEW as a mineral filler in HMA was found to be suitable.

可回收混凝土和陶瓷废料在热拌沥青中的应用

研究人员最近一直在解决的一个重要问题是来自不同行业的各种废物的回收。每年，数百万吨的废物被释放出来。污染和安全，具有成本效益的处理是这些废物的关键问题。本研究旨在探讨混凝土废料(COW)和陶瓷废料(CEW)作为热拌沥青(HMA)填充材料的可用性。首先，在该方向上进行了一系列试验，确定了最佳沥青含量。5种不同的沥青含量(即4.5%，5%，5.5%，6%和6.5%)用于制备沥青混凝土样品。然后对制备的样品进行马歇尔稳定性(MS)测试，使用不同的填料比例，包括石灰石(LS)、混凝土废料(COW)和/或陶瓷废料(CEW)。选择具有最大稳定性的含4%填料的沥青系列，以25%、50%、75%和100%的LS填料代替COW或CEW。因此，发现在HMA中使用COW或CEW作为矿物填料是合适的。
