Özet

Owing to climatic and environmental conditions, conventional asphalt pavements often fail to demonstrate the expected performance, resulting in surface deteriorations. Asphalt binders are modified using various additives to mitigate these deteriorations and enhance pavement performance. The excessive consumption of polymers as modifiers has recently raised environmental concerns, increasing interest in bio-based alternatives. In this study, a novel bio-based asphalt modifier, the boron-added resin compound (BARC), derived from resin and boron oxide, was utilized under laboratory conditions to enhance asphalt performance. Rheological tests, including dynamic shear rheometer (DSR), multi-stress creep recovery (MSCR), linear amplitude sweep (LAS), and bending beam rheometer (BBR) tests, were conducted on both unmodified and BARC-modified asphalt binders. The findings indicated that BARC significantly improved asphalt's resistance to rutting at high temperatures, extended fatigue life, and expanded its application range according to traffic loads, with optimal performance observed at 1% BARC content. Specifically, the fatigue life of the 1% BARC-modified binder increased by 11.13 times at a 5% strain level compared to the unmodified binder, exhibiting more elastic behavior and suitability for extremely heavy traffic conditions. Consequently, the novel bio-based additive, characterized by a short production process and low cost, is considered a promising alternative modifier for asphalt pavements.
