Evaluation of the impacts of basalt fibers and hydrothermal liquefaction bio-oil on the fracture properties of asphalt mixtures at intermediate and low temperatures

Results in Engineering
Cracking remains one of the most critical distresses in asphalt pavements, with aging-induced embrittlement accelerating crack initiation and propagation under repeated loading. Although bio-oils offer rejuvenation potential and fibers provide mechanical
