High-Temperature Performance Evaluation of Asphalt Mixtures by Adding Short-Chopped Basalt Fiber

Adding basalt fiber (BF) can effectively enhance the performance of asphalt mixtures and improve service quality pavement. However, effect BF on high-temperature different types systematic test analysis are still not well known. To address this issue, three typical AC-13, SMA-13, SUP-13 were selected. Wheel tracking test, uniaxial penetration dynamic modulus creep conducted. In addition, relevant parameters stability, strength, index, flow number analyzed. The results showed that adding into mixture could significantly, indicating is an effective solution to rutting deformation damage Moreover, parameter stability presented approximate polynomial correlation with number, respectively. These findings provide a certain theoretical reference for evaluating BF-modified mixtures.
