Abstract

Coir fibers (CFs) and micronized rubber powder (MRP) can be derived from low or negative-value agricultural/industrial waste streams and provide economical and sustainable pathways to develop high-value engineered products. This study investigated the influence of adding these modifiers on the performance characteristics of asphalt binders. Samples were produced using a mixture of slow-setting anionic asphalt emulsion with various quantities of MRP (at 0, 2 and 10 wt. %) and two levels of short CFs ( ~ 1 mm and 2 mm) with different fiber contents (at 0, 2 and 5 wt. %). The performance of modified asphalt samples was assessed by penetration depth (PD), softening point (SP), and penetration index (PI). Full factorial statistical design was structured to reveal the influence of main effects of the wt. % MRP, wt. % CFs, and CFs length and their interactions on the performance of the modified asphalt. Based on the statistical experimental design, linear regression analysis was performed. The linear regression showed that adding CFs and/or MRP consistently reduced PD, increased SP values and improved PI values. The length of CFs significantly affected the performance, which becomes more distinct with the increased weight content of CFs at 5 wt. %. It was also discovered that the combined addition of short CF and MRP achieved similar PI values at the same weight content of MRP alone.
