Abstract
In view of the disadvantages of surface reflection cracks that are easy to occur after asphalt layer overlay on airport cement pavement, a laboratory beam three-point bending test was conducted to investigate the generation and development process of reflection cracks of modified asphalt and cement composite beams under different types of bottom cracks, and the ability of different modified asphalt mixtures to resist surface reflection cracks was evaluated. The results show that under the three-point bending loading mode, the development process of cross crack and transverse crack is similar, and the influence of vertical crack on the reflection crack is small. The NRP-modified asphalt mixture has a better ability to resist reflection cracks than the ordinary SBS-modified asphalt.
