Abstract

To improve the road performance of bio-modified asphalt, this paper mixed 3% organic montmorillonite with bio-modified asphalt, and prepared organic montmorillonite bio-modified asphalt by adopting the high-speed shear method. Meanwhile, by carrying out three aging tests of RTFOT, PAV and UV and combining DSR, MSCR, BBR and Brinell viscosity tests, the high and low-temperature stability and anti-aging properties of organic montmorillonite bio-modified asphalt were comprehensively analyzed from the perspective of rheology. The experimental results show that bio-asphalt has sound compatibility with base asphalt. The high and low-temperature performance of bio-modified asphalt is basically similar to that of base asphalt, but its anti-thermal aging and UV properties are poor. The mixing of organic montmorillonite with special intercalation structures can significantly improve the rutting factor, creep recovery rate, and Brinell viscosity of the bio-modified asphalt, reduce its unrecoverable creep compliance, and significantly improve its anti-rutting and aging properties.
