Abstract

The study you’ve described focuses on the use of reclaimed asphalt pavement (RAP) as a substitute material in asphalt mixtures with varying percentages of RAP content (25%, 50%, and 75%). The main objectives of the study are to assess the degradation of aggregate components (coarse, fine, and filler fractions) of RAP and to evaluate its impact on the durability of the resulting asphalt mixtures, specifically by measuring the Remaining Strength Index (IRS). In summary, the study highlights the trade-off between using higher percentages of RAP to recycle old pavement materials and maintaining the durability of the resulting asphalt mixture. It demonstrates that as the RAP content increases, the degree of degradation in the asphalt mixture also increases, leading to a decrease in durability as measured by the IRS. However, it’s important to note that even with higher RAP content, the asphalt mixture may still meet certain durability requirements, albeit with a slightly reduced IRS value. The findings can help inform decisions in asphalt pavement recycling and mix design for sustainable and cost-effective road construction.
