| Abstract: |
| A SMA 5 asphalt mixture was designed with self developed high viscosity asphalt（HVA） as binder. Road performance and dynamic mechanical properties of the mixture were evaluated before it was applied in practical engineering. Results show that the SMA 5 HVA mixture performs better dynamic stability, flexural tensile strain, tensile strength ratio and fatigue life, especially for dynamic stability and fatigue life. Application of this SMA 5 mixture showed good prospects in practical engineering. |
