Abstract

The properties of asphalt mortar with fiber added directly affect the road performance of SMA. Based on the raw material performance test, the paper carried out the dynamic shear rheological test (DSR) and the bending beam rheological test (BBR) on the SBS modified asphalt mortar with nickel iron slag fiber. From the macroscopic point of view, the high temperature and low temperature performance of the asphalt mortar with fiber were analyzed and compared; Scanning electron microscopy (SEM) was used to analyze the distribution of nickel iron slag fiber in SBS modified asphalt and the interface structure between fiber and modified asphalt from a microscopic point of view. The results of the study show that the best high and low temperature performance is the addition of mineral No. 3 nickel iron slag fiber, and its compatibility with asphalt is also best.
