Analysis of Influence Factors on Anti-Rutting Performance of Fiber Asphalt Mastic and Fiber Asphalt Mixture
In order to improve the rutting performance of asphalt mastic and asphalt mixture, taking rutting factor, phase angle and dynamic stability as the target, the influence on anti-rutting performance of asphalt mastic and asphalt mixture and its variation law are systematically studied by filler-asphalt ratio, filler type, fiber type, fiber content, aging degree and gradation type using dynamic shear rheometer test, rutting test and rotating thin film oven test. The results show that: The filler-asphalt ratio should not be more than 1.4. Fiber to improve the anti-rutting performance of asphalt mastic is better than cement and mineral powder. The improvement of Dolanit fiber on anti-rutting performance of asphalt mastic and mixture is the best. With temperature rises and fiber content increases, the influence of fiber on anti-rutting performance of asphalt mastic decreases. As fiber content increases, the anti-rutting performance of asphalt mixture first increases and then decreases. The anti-rutting performance of asphalt mastic after aging is better. The anti-rutting performance of SMA asphalt mixture is the optimal. Research results have great guiding significance for fiber type selection, fiber content selection and improving asphalt pavement performance.
