| Description | Journal: Iop Conference Series: Materials Science and Engineering The modified asphalt binders and mixtures were prepared by SBP directed vat set modifier with recycled polyethylene as the main component. The effect of SBP modifier on the high-temperature characteristics of asphalt was characterized and analyzed by dynamic shear rheometer and differential scanning calorimeter. Thus, the pavement performance of SBP modified asphalt mixture was evaluated, and the test road was paved. The results show that the high-temperature rheological characteristics of asphalt were significantly improved with the SBP modifier. The high-temperature performance grade (PG) can be increased by 2-3 classes, but the improvement in high-temperature sensitivity was not noticeable. The SBP modifier can improve the low-temperature performance of asphalt to a certain degree, but this is not enough to change the low-temperature performance grade of asphalt. The high-temperature and water stability of SBP modified asphalt mixture are better than that of SBS modified asphalt mixture, which is more suitable for high-temperature and rainy areas. |
