Abstract

Reclaimed asphalt pavement (RAP) is a valuable commodity originating during processes of road/highways rehabilitations, resurfacing in the cases of the revelation of underneath-placed layers. Removed material can be successfully recycled and utilized as a supplementing material for new hot asphalt mixes. However, its dosages are limited because of variations in properties of aged bitumen compared to fresh material and, thus, a significant amount of waste material is remaining as waste products. Nonetheless, this commodity may find usage in the construction industry that suffers from a shortage of high-quality and easily available aggregates. This work aimed to investigate the optimal substitution of mined natural aggregate with commonly available RAP in order to produce composites with the comparable mechanical performance of reference ordinary Portland concrete. The aggregate substitutions up to 100% with RAP have been studied with a combination of mechanical and analytical techniques. Obtained experimental data showed changes in the porous structure, mineralogy, and in the amount of formed cement-related hydration products that influenced the mechanical performance of produced composites. Composite with 10% of natural aggregate substitution with RAP has shown the strength class C16/20 after 28 days of water curing, according to the EN 206-1. Such innovative products could be utilized in the construction industry. The usage of waste RAP could contribute to preservation of our environment for future generations.

摘要

再生沥青路面（RAP）是一种有价值的材料，产生于道路/公路修复过程中，当下面的层位暴露时进行重铺路面作业。移除的材料可以成功回收并用作新热拌沥青混合料的补充材料。然而，由于老化沥青与新鲜材料相比性能存在差异，其用量受到限制，因此大量废料作为废品残留下来。尽管如此，这种材料可能会在优质且易于获取的集料短缺的建筑行业中得到应用。这项工作旨在研究用常见的RAP最佳替代开采的天然集料，以生产出具有与参考普通硅酸盐混凝土相当机械性能的复合材料。通过机械和分析技术相结合的方式，研究了RAP替代率高达100%的情况。获得的实验数据表明，多孔结构、矿物学以及水泥相关水化产物的数量发生了变化，这些变化影响了所生产复合材料的机械性能。根据EN 206-1标准，用RAP替代10%天然集料的复合材料在水养护28天后显示出强度等级C16/20。这种创新产品可用于建筑行业。使用废弃的RAP有助于为子孙后代保护环境。
