- Abstract:
- In order to study the performance of direct coal liquefaction residue (DCLR) modified asphalt mixtures, 10% DCLR (mass ratio to base asphalt) modified asphalt mixtures and composite DCLR (2% SBS+15% rubber powder+10% DCLR) asphalt mixtures were prepared, and their performance was compared with hot mix asphalt mixtures and SBS modified asphalt mixtures. The experimental results showed that the addition of DCLR can improve the high-temperature stability and water stability of asphalt mixtures, But there is damage to its low-temperature performance; The low-temperature performance of composite DCLR asphalt mixture has been greatly improved, and its high and low temperature performance and water stability are significantly higher than those of SBS modified asphalt mixture
