摘　　要：利用自主研制的高黏沥青(HVA)设计了一种SMA-5型高黏沥青混合料,通过室内试验评价了其路用性能和力学性能,并开展了工程应用.结果表明:SMA-5型高黏沥青混合料具有良好的路用性能,其动稳定度、破坏应变、冻融劈裂强度比和疲劳寿命均优于SBS改性沥青混合料,其中动稳定度和疲劳寿命优势明显;工程应用也证明了SMA-5型高黏沥青混合料的应用潜力.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 sta- bility, flexural tensile strain, tensile strength ratio and fatigue life, especially for dynamic stability and fa- tigue life. Application of this SMA-5 mixture showed good prospects in practical engineering.
