| Abstract: |
| The dynamic mechanical properties of EVA/SBS modified asphalt were investigated and compared with those of original asphalt and SBS modified asphalt.The results showed that the complex modulus and rut resistance factor of EVA/SBS modified asphalt increased obviously and tanδ decreased significantly when compared with those of original asphalt and SBS modified asphalt，which indicated the high temperature elasticity and high temperature rut deformation resistance of EVA/SBS modified asphalt were improved and the temperature susceptivity decreased；with dynamic vulcanized EVA/SBS，the high temperature elasticity，high temperature rut deformation resistance and temperature susceptivity of the modified asphalt were further improved. |
